Practical measurement "sound and Vibration Assistant.

Hallo,

ICH möchte eine Maschine von Gerauschemissionen untersuchen. Dazu soll mit Hilfe der Norm DIN EN ISO 11201 der emissions-Schalldruckpegel altitute werden. ALS Messhard-und software are mir following components available:

Software:

-LabVIEW 2010
-Noise and Vibration Assistant 2010
-Windows 7

Material:
-NI 9234 Messsystem mit NI USB-9162
Condenser-Mikrofon
-Laptop

ICH möchte mit dem 'Sound and Vibration Assistant' ein Oktavspektrum bzw. Ein 1/3 - Oktavspektrum-> Terzspektrum aufnehmen. Dazu sind mir ein paar aufgekommen questions.

-Laut Norm is die Messdauer bei measurements in 30s Oktav-Terzbandern fur Frequenzbander mit Mittenfrequenzen von 160 Hz low sowie für die 15s und Frequenzbander mit Mittenfrequenzen von 200 Hz und high.

  • Wenn ich alglemein eine measurement starte andert sich jede Sekunde bei einer sampling frequency von 51, 2 k und den zu lesenden 51, 2K das all Spektrum von samples. Also jede Sekunde ein neues result. Wenn ich also 30 Sekunden mass, means are dann, dass ich aus 30 results (Pro result ein entire Terzspektrum) den Mittelwert bilden kann bzw. muss?

  • Wie ich dann die unterschiedlichen Aufnahmedauer auf die Frequenzbander anwenden should? Should ich die highest frequency und niedrigste frequency q und dann der Zeit messen vorgegebenen correspondingly?

-Laut Norm should as jedes Frequenzband eine Pegeldifferenz von mind. 10db zum Umgebungsgerausch available breast.

  • Also ich z.B. das Hintergundgerausch über 30 Sekunden mass. Dann jedes Frequenzband über 30 Mittelwert den Werten as image. DAS same mache ich dann bei Betrieb der Maschine. Kann ich dann die dB values direkt miteinander comparisons sprich Gabriel bilden die um zu sehen, ob die Pegeldifferenz 10dB kleiner oder grosser ist oder muss ich eine Logarithmische Pegelsubtraktion paper? nach der Formel section = 10 * lg(10^0,1*L1-10^0,1*L2) z.B.?

-Wenn ich den aquivalenten Dauerschallpegel Leq messen möchte, die Die Formel Gesamtmessdauer wo mit einfliesst, wird dann der Mittelungspegel über eine Sekunde bei einer sampling frequency von 51, 2 k und den zu lesenden samples von 51, 2 K berechnet oder ist das result über die ganze Messzeit (wieder 30 Sekunden z.B.) berechnet worden? Oder ich aus den werten eine weitere Mittelung paper individual should?

Viele Grüße

Hallo Voyage200,

Wenn ich alglemein eine measurement starte andert sich jede Sekunde bei einer sampling frequency von 51, 2 k und den zu lesenden 51, 2K das all Spektrum von samples. Also jede Sekunde ein neues result. Wenn ich also 30 Sekunden mass, means are dann, dass ich aus 30 results (Pro result ein entire Terzspektrum) den Mittelwert bilden kann bzw. muss?

-> Should der Arbeitsspeicher gross genug breast ware are ermöglichen das auch Signal 30 Sekunden gepuffert mit dem mittelfristig-Verbraucher-Entwurfsmuster appears und die exported analysis often.

Wie ich dann die unterschiedlichen Aufnahmedauer auf die Frequenzbander anwenden should? Should ich die highest frequency und niedrigste frequency q und dann der Zeit messen vorgegebenen correspondingly?

-->--> Als Tipp Ja am examples of Anfang arbeiten mit den einfachen und Express VI. Powerful exported Programmieren mit den Low Level VI.

I hope sharp Antworten helfen Ihnen weiter

und verbleibe mit thank wurde

  • sound and Vibration Assistant. Speaker output

    I am new to the sound and Vibration Assistant and he had to get monitored sound of a surfboard 4722 the speaker to computers.  I can capture data and display it, but I want, but can't seem to find a way to get the sound to the speakers.  Thanks for any help

    Hi Mike.

    Unfortunately, the Sound and Vibration Assistant doesn't have a built-in way to route your signal input to your speakers.

    However, if you have LabVIEW, you can add a step to run a LabVIEW VI that generates output a file from your computer speakers (or external speakers).  You must write a LabVIEW program that either acquires a signal or load a file of recorded signal, then this signal to your speakers.  "You will most likely use the Play Waveform Express VI of the Express" exit pallet on the block diagram.  "After you wrote this program, you need to add a step in the sound and Vibration Assistant using the Add a step" run a LabVIEW VI.

    I hope this helps.  Good luck with your application!

  • How can I integrate IPS into the Sound and Vibration Assistant 6.0?

    I found out how integrate time domain signals to m/s in S & V 6.0 Wizard, but not IPS.  I could scale the signal, but the axis labels will be wrong.  How can I integrate directly to the IPS of the entrance of G?  Also, is there a way to do the same thing for the analysis of frequency domain?

    In the audio wizard and vibration - step vibration level, use

    on the integration tab - select double integration and click export integrated signal

    Now you have a shift of signals in the right units.  Make a spectrum on that and you get a spectrum of integrated signal.

  • More Sound and Vibration - Leq measurement?

    Hello

    I'm new to following Sound and Vibration and can't seem to find how to measure Leq. To clarify, I do not have LabView with this package, just the Sagno & Suite 2010. Currently, the only options are linear, exponential, maximum and equal trust (all found in the analysis of Octave SPL stage).

    Should I have LabView to perform a running Leq or Leq measurement?

    Hello

    Examines the LEQ under analysis. Take a look at the following screenshot.

    I would like to know if this isn't what you're looking for.

  • Purchase / upgrade of LabVIEW with more Sound and Vibration

    Hi, supporters OR Forums,

    I'm new in LabVIEW but I'm working on a project that needs to use LabVIEW in these toolkits: DAQmx, PID and then Sound and Vibration Control.

    In order to experience on the vibrations, I need to use screws of Suite Sound and Vibration, which was not purchased in my Institute. We had the license for LabVIEW 2009 SP1. Unfortunately, I have a VI file written in LabVIEW 2010 my partner. According to the records of view VI, there is a lack of following screws:

    -SVFA Power Spectrum.vi
    -Application Directory.vi
    -SVT FFT .vi spectrum (Mag-Phase)
    -Frequency response (Mag Phase) .vi SVT
    -SVFA amplitude and Phase Real and Imaginary.vi
    -SVL get spectrum subset.vi
    -SVT UFFT58 write.vi
    -SVT UFFT58 write record 6 vi
    -SVT HFFT58 close file.vi

    I would like to confirm if these screws are supplied in the detroit and Viration Suite or / and other toolkits. If all of them can be found in the following Sound and Vibration, what I have to do is to buy the offer away from NOR, is it not? How much should I pay for this Suite.

    On the other hand, if we upgrade from LabVIEW 2011 (which is said to be able to deal with better timer - for the function of data acquisition), how much in total so also buy us more Sound and Vibration 2011.

    In comparison, which of the above two options is preferable in terms of price.

    For your information, I am working on my thesis at University in this means we would like to have a university degree.

    Plesea give me ideas on this subject. I'm sorry if my post is not fit to be posted here but I sent 2 emails to NI Germany (1 for the customer on the Web page Service NOR) and 1 in the Sales Department, but there is no response after more than 3 weeks.

    Thank you very much.

    Kind regards.

    Thinh Vo

    Hi thinhvo,

    All of these VI are included in the Suite Sound and Vibration, which means it's the only additional package that you would need to buy.  On the site OR in the States, the Sound and Vibration Measurement Suite USD $4119 costs.  Since I'm an applications engineer, I'm not in a position where I can advise you on the price, and I am sorry to say that it will be easier for you to contact your engineers in sales in Germany (I guess you are in Germany).  You may have better luck calling into lines of support rather than by e-mail.

    Thank you

  • The NI9423 will work with Sound and Vibration VI

    Will be that the NI 9423 mounted on a chassis cRIO work with the NO audio and vibration of VI?

    I have an optical encoder of 10-30 V 100 pulses/revolution and would like to make angle field order analysis with her.

    is the NI9423 a card appropriate for this purpose or is something else better suited, I'm open to change the type of encoder if necessary.

    Hi Bodger

    How fast do you think the tree to turn to? The speed of switching module is able to pass to the 1uS extremely quickly. This means that you should be fine unless you are turning the tree at a ridiculously fast speed of approximately 600000 RPM.

    Regarding the reading of signals with the sound and vibration screw, you should be able to do this using the digital tachometer functions.

    Thank you very much

  • Construction of the installer wants to sound and Vibration Distribution but my vi do not need

    My vi contains some common entries and a regular to read some 4-20mA, see attached data acquisition.

    So I save a new project and build an exe with the vi, no problem, see project files attached.

    Then I start building the Setup program by clicking below to install the libraries. I think that I click on the right side of the law library?

    But lo! OR say I need sound and Vibration Distribution, now, where does? My vi has no sound and vibration functions...

    I click on no, the installer don't build Labview.

    I click Yes, Labview kept asking me where is the audio library and vibration.

    I bought a NI Developer suite, expensive things like costs about US$ 4000 +. My software vendor told me that I don't have the license for the sound and Vibration Distribution.
    So, what should I do? Clicked on some bad settings during the generation of the installer? Is there a way around this problem? Thanks in advance!

  • BlackBerry Z3 sound and vibrate does not at the same time

    Hi support them.

    I recently purchased the BlackBerry Z3.

    It supports no sound & vibrate at the same time.

    In Normal mode, I activated sound and vibration, but it only gives sound for incoming calls/messages.

    (does not vibrate)

    In vibration Mode, it only vibrates.

    It's the first time I use a Blackberry and I'm upset with the basic functionality works do not.

    Please answer.

  • Problem of sound and vibration

    Hi all:

    I met a problem when using audio Toolbox and vibrations, when I select a sub vi of this Panel of the Toolbox, for example the 'filter '.

    VI, I see very little setting in the ICO (SpxImage1.jpg), but when a double click and enter in the Properties dialog box, I see more options (SpxImage2.jpg).

    what I want to know is, is it possible to set up the details in the parent vi vi sub? because these parameters are variables to my program

    Thank you

    Hi adobefree...

    Right-click on the express vi and select "Open the front panel", you can now see the express vi blockdiagram. You can store as a new vi and work with it. With the new vi, you have all the controls in the dialog box.

  • Assistant OR-9234/Sound and Vibration: being reset to zero (crazy) automatically input signals

    Hi all

    I have a voltage source and a force as entries in a sensor module DAQ 9234.

    The software focuses both signals whenever they change. For example, if the voltage is read by data acquisition increases up to a constant value, the software will trace an increase in tension, followed by a slow return to zero. Similarly, if I increase the force applied to the force sensor and keep it at a constant value, the program will draw an increase in force, followed by a return to zero.

    Here is a graphical representation of the problem, which uses the sensor force for example:

    The sensors are passive. The sensor is a PCB 02 208, and the source of tension comes from a LDM-1000 signal conditioner, which receives a signal from a MHR 250 LVDT. By the LVDT core displacement changes are interpreted by the signal conditioner, which translates as the measure of a voltage value that can be read by data acquisition.

    Thank you in advance.

    I assume you have the rule 9234 on coupling AC mode, while you should use DC coupling.

  • Why the information for my pickups TEDS not displayed in Assistant Sounfd and Vibration when I create a step of acquisition?

    I used to have TEDS Panel for my microphone when I was creating a new stage to acquire data in the Sound and Vibration assistant.  It is not the case today.  Any idea?

    Hello

    It seems that your configuration of TEDS able & Automation has been lost.  If you open Measurement & Automation you can configure your device TEDS to see something similar to the attached picture.  Once configured in Measurement & Automation then close off Assistant Sound and Vibration, and then start it again. Sound and Vibration Assistant asks simply Measurement & Automation for TEDS devices configured here.

    Thank you

  • LabVIEW 8.6 sound and measure suite not installed properly under Vista 32 or 64 bit

    I apologize if this isn't the right place for this post, but I need a solution. I recently bought LabVIEW 8.6 Developer Suite with the Suite Sound Measurement and to create a program of NVH testing at my company. I am a newbe to Labview, but I've been a programmer/hardware geek since the days of the TRS-80 model1. Here's my problem. I installed the following developers DVD package on my Office Windows XP Professional and all goes well. I see the following Sound and Vibration Measurement listed under LabVIEW 8.6 able & Automation Explorer, and examples of the Toolbox for work in LabVIEW. When the laptop I bought to do my current job came with a Vista Business Edition 32 bit version installed I found the following problem. On this machine and two other machines to Vista (64-bit and a 32 bit) I tried, the installation does not record the Souind and vibrations under LabVIEW 8.6 Suite and they show Sound and Vibration toolkit as not installed in the examples section. In the Panel by virtue of National Instruments, all 4 machines show the Suite Sound and Vibration as installed 6.0. I have tried to uninstall, reinstall, change in the control panel and reinstall from DVD without change in the result. I really need get the laptop works as it's my real development and test machine. XP Setup is not an option because the machine newly purchased with a high-end sound system and downgrade XP was not available. I'm out of ideas.

    I wanted to close what I got it finally works. This time, I uninstalled the audio and vibration of the LabVIEW control entries in uninstall Vista. Then re-installed and now it works. Before there were three entries, one for the suite, one for the runtime and one for the Toolbox. After having removed all three and reinstall it from the DVD, only subsequently arises, and everything seems to be good.

  • Audio examples and vibration - activate or not?

    Hello

    I am a student and I use the evaluation version of LV I am playing with audio examples and vibrations, but I don't see the block diagram only the façade. It says to activate LV. Need to activate the OAS tool to see examples block diagram or is there a trial version?

    Hey Charlie,

    Please see the following knowledge base:

    http://digital.NI.com/public.nsf/allkb/862567530005F09C8625675F00711756?OpenDocument

    If you are using the evaluation version of LabVIEW, 'you will not have access to diagrams of screw not available in the basic development systΦme."

    Your options are:

    1. buy the sound and Vibration Toolkit (and LabVIEW so),

    2 buy the version of LabVIEW Student install of the Student Edition (only this version includes noise and vibration measurements): http://www.ni.com/labviewse/compare/

    You can check with your University/College to see if they bought the box tool.

    Hope it will be useful,
