Acceleration signal initial height under impact load - LabVIEW

Hi all

A hemispheric 10.6 kg strike ball weight a sample of concrete went the distance of 200 mm.

The acceleration recorded using labview is illustrated below. Anyone know why I get this initial peak (ms 3 to 5.7) initially because acceleration must go down at impact?

Thank you all.

The test of the room shows an acceleration to rest of about 0 of + 20 when you deposit the coin.  I guess that the 1 g of gravity has been canceled, and that when the beam begins to descend, it is saved as an acceleration positive, right?  [Enter the right signs to something like this can be a real challenge!].

I'm happy, I think that "the data is correct" was right.

  • Disables the killer wireless 1535 under heavy load

    I just received a brand new 15 R2 in the mail a few days ago and have had any other problems with the wireless. It works very well under normal load IE internet browsing or streaming videos. When I try to download a game on steam or push the signal degrades slowly until the wireless card turns off. Then, you cannot activate the card via the hardware switch or click with the right button to enable. Any ideas? See the reference video.

    cs_setInnerHtml ('video_5eed075f-5174-43dd-b4cf-997c702184ea', ");

    I uninstalled all the software/drivers killer, deleted the drivers and reinstalled the drivers Slayers of the killer and dell Web site.

    Alienware has finally got resolution. They came and replaced the 1535 with an Intel AC 8260 killer. I'm going on two days with zero problems and more than 100 GB downloaded on my 5 GHz network to nearly 15 MB/s, which is what my internet caps to. Kudos to Alienware to send to the Intel card the next day. There he sent Tuesday of this week and the technician was home Wednesday afternoon. So far so good. I hope that Killer will solve questions 1535 a Windows 10 and 5 GHz, but unfortunately with imminent deployment, I have not time to wait for her.

  • How to display the signal on a waveform graph in Labview Signal Express?

    Hello

    I want to display a signal in Signal Express 3.0 in a "waveform table", but don't know how to do it and I think that it may be impossible?

    In Labview, there are two ways to view data, a 'waveform table' or a 'waveform graph. The great thing with 'picture of waveform' is that it allows you to set a length of history and you can see the data move to the left (option graphic strip) that samples are recovered. It works perfectly.

    In Signal Express I can only select "Graph XY" or "Waveform curve" by doing a right-click of the mouse, but I can't select "table of waveform. Is it really true that it is not possible to view data in a graph of waveform "with Labview? (1 analog signal during streaming, 100 samples to read at the rate of 1 K)

    Thank you in advance,

    Enrique

    Hi Enrique.

    You are right that there is currently no graphic waveform in SignalExpress. The thing nearest you can join, is saved data under a log and then he looks one when recording (which I know this isn't quite the same interactive behavior).

    For your last comment, you wrote 'waveform curve', but I guess you meant 'picture' here as well.

    Sorry about that. We recently received this request, then perhaps in a future version.

  • How to get the width and height of a loaded image?

    Hello world

    Clicking on one of the 26 letters of the alphabet, I display 15 logos, starting with the first brand whose initial is the clicked letter.

  • Signal Express version unknown problem with Labview VI

    Hi all

    I am trying to run 2010 Labview Signal Express VI. It gives me "unknown version" problem. When I checked for Labview versions, he said 10.0f2 and Signal Express can read the version of LabView 2010. I don't understand this. 10.0f2 is not just a patch for version 10.0? I will appreciate if someone can help me with this.

    Kind regards

    Kanu

    Hi Kanu,

    I tried to write a simple VI and its importation to the Express Signal and I have not had any problems. I use 32-bit LV2010f2 and Signal Express 2010. I have attached the VI I used so that you can try it yourself. I followed the instructions of this KB to create a distribution of the source file. If you follow this KB and still can't make it work, can you please post the VI?

  • time of Labview application to run on pc without slow loading labview environment!

    Hello!

    I did an executable file of my project.

    When I run it on my pc (where installed labview development), I don't have problems and instantly loaded application.

    I tried to run the exe even on several other computers, all having the same trouble - the façade poped up after 2 minutes of waiting.

    I made a little test and pluged out the network cable - it solved the problem, but I need the network.

    I tried to disable the update automatic root certificate (as advised on a thread) but no luck.

    I searched the forums and found similar problems - but not solutions.

    Please help me.

    Guy.

    Yes. Problem solved.
    first turn off the auto root certificate update - no problem to find how to do this.
    Then type regedit in start-run, my computer-hkey current user-software-microsoft-windows-currentVersion-winTrust-trust suppliers-software publishing - just right-click on the state-change-change the character c to e, then press ok.
    Good luck and let me know if this helped.

  • VI using ActiveX runs under XP, load in Win7 64 bit, but hangs in Win7 32 bit.

    I have a VI that works under windows XP, supported in Windows 7 64 bit (for editing only) but hangs Labview in windows 7 32-bit.  I know the code works, but I have not tried on this particular PC before so I guess that there is an error of configuration somewhere, but dang if I can find it.

    I've included a screenshot of the error as well as a copy of the VI in question.

    UPDATE:

    Problem solved.  It turns out that TI requires a developer version of spectial of their drivers to work with labview, otherwise labview get permission to use the control and the accident.

    Installed the Dev and now everything is normal.

    The stupid thing is that actually, I knew that, but it's been so long that I had to set up a new PC for work with labview that I forgot.

  • getting dropped under heavy load of iSCSI LUNS

    Hello


    I found a few forums on this... but not a response yet.

    I have a Hp Lefthand 4300 cluster for the storage, connected to 2 x DL360 G7 ESXi 4.1 via iSCSI (Hp edition) guests and a Procurve gigabit switch dedicated for iSCSI. Whenever I run a backup down the LUN for a few seconds (usually 5, however it was as much a minute).

    Things, I tried...

    Updated software from the left to the latest version

    Updated all the HP firmware on the hosts

    Update to the latest drivers HP Boradcom on ESXi hosts

    Changed the timeout 1400 (esxcfg-advcfg - s VMFS3/14000/HBTokenTimeout)

    These servers come into production in the new year... Please please can someone help me solve this problem?

    I call open with Vmware and HP, nor was particually useful, Vmware has suggested I called HP and updated card drivers NETWORK, HP simply said that it was a network problem and closed the call... Thank you!

    I intalled surveillance under tension and can not see all ports dropped etc. All the equipment is new and the LAN cables are Cat6.

    Don't really know where to go from here!

    The exact error I get is...

    Lost access to the volume (4cf7b1ac-5fdcc218-5c2e-1cc1dee48e30)

    We have recently changed some hosts who also had problems on a heavy load with iscsi San connections. We used hwiscsi (TOE), Broadcom adapters (was a recommendation from different vendors) before and this has recently changed to swiscsi (with Jumbo).

    No. dropped / resets on connections over this host. And a much faster flow of vm (tested with IOmeter).

    We also saw a much beter performance (throughput) on hosts with NIC configured to swiscsi on comparisation of hosts with an iSCSI HBAS (Qlogic 4062).

    We use VMware ESXi 4.1 (latest patches).

    Problems with broadcom TOE (hwiscsi) on HP DL360G6 also on Dell M610 blades.

    SAN: EqualLogic PS5000 PS6000, PS5500, PS6500,

    Switches: Juniper weer Jumbo Frames and flow control.

    So I recommend you also use swiscsi on these broadcom adapters.

    If you are looking for broadcom issues with vmware, find others with similar experiences.

  • fan comes under low load

    I'm coming from a 2011 macbook air to a 2015 macbook pro 2.5 ghz, 16 GB of ram. What's weird, is that the fan is more using the same applications as air. With my air, I almost never heard.

    Just have open illustrator and a few tabs on chrome, including web animations and the fan starts to kick. It's pretty boring. I don't mind the fan is very loud, if I'm doing intense stuff. I've tried everything as reformatting and loaded just the Basic apps that I use, and the same thing happened.

    Is this normal with everyone else, or is there a potential problem with heat sinks or something? 10.11.3 updated

    Hmm. generally, the recommendation would try resetting the SMC http://support.apple.com/kb/ht3964

    "reformat everything" would include this suggestion into effect.

    You can try the Apple Diagnostics http://support.apple.com/kb/HT1509 running

    Not definitive by any means, but it would be useful it it produced an error code.

    You can always take assessment and test 'Apple Service Diagnostics'

  • SoftMotion module only runs under 32-bit labview and not 64-bit labview

    Good day everyone,

    I downloaded the softmotion module for my Labview 2013 64 bit but when I try to create a new set of solidworks there is no option for this.

    But when I installed the 32-bit version of Labview 2013 I could see the possibility of creating a new set of solidworks.

    Why can I not see the option for the Labview 2013 64 bit?

    P.S. I am using Solidworks 2014 64 bit Premium.

    Thank you

    This is the 64-bit

    This is the 32-bit

    The softmotion module is not supported for 64-bit LabVIEW.  You can see what we support in the link below.

  • Sensor of impact and LabVIEW?

    Hello

    I want to measure the dynamic force applied to an object when it is hit by a bullet of hockey moving at a maximum of 40 m/s.

    The problem is I want to monitor the rate of change of force and not the maximum.

    I won't use an accelerometer like the vibrations caused by the object to interfere with the release of the accelerometer data.

    Are there packages of sensor on this compatible with LabVIEW and NOR-9172

    Hi Kamilan-

    Dytran cable you are referencing seems to be the right cable to connect the NI 9233 (as long as the cable is a BNC connector male, it seems to come from the image on the product page).

    And Yes, you can use DAQmx as driver for the 9233.  It works perfectly for your sensor.  I would recommend callind Dytran and ensure that the cable is 1) a male BNC connector and 2) the right cable for your sensor, because I can't comment directly on their equipment.

    Good luck with your application!

  • Under pulse in LabVIEW FPGA

    I have a disc that rotates at about 3000 rpm. Whenever this disc rotates one revolution, it generates a pulse. I want to take this impulse 100 samples (each 3.6 deg). I want to do this I want to divide the subsidiary pulse in 100 pulses, the time between each of these subsidiary pulses (samples) is constant, however, the speed of the drive can vary from 3 or 4 RPM. This means I can't say exactly how long a disc rotation will take. This is why I can't have a fixed sample rate because in order to get the same time difference between each auxiliary pulse, I need to dynamically change the number of samples to be taken depending on the speed of rotation of the disc. I want to acquire data of four sensors of pressure OR-9237, cRIO-9114. I'm using LabView FPGA.

    Any help, direction, or other ways you would to do this will be much appreciated. I'm new fairy on LabView . I also hope that I have post in the right section.

    I use Pagemaker 7 on a mixture of Windows 7 Pro, 32 & 64 bit Dell i5 and i7 PC hard drive to work with complex graphics files.

    These computers all display the chart pages quickly Pagemaker - about 1 second for each complex page.

    A new Dell Xeon with Windows 7 Pro 64 bit with 8 GB, 250 GB SSD and 1 TB hard drive works Pagemaker 7 OK. Logically, it should be useful faster than our other PC.

    The Xeon pilots have been verified also updated.

    SuperFetch and Windows Search are both "started"... but it makes no difference if they are 'off '. Manager tasks indicate > 6 GB 'Cached' and 'Available' with Pagemaker 7 and a graphic 128 MB .

    Pagination is "managed automatically for all readers" with 8 GB allocated on SSD.

    Please, no guidance on why the initial graphic display should be so slow when later it's instant?

    I am building an app to read a signal in a cell in charge of RS & amplifier using a USB6210 data acquisition card. I ' v tried SE & Diff connections, and I see a change in signal when I apply a load, but it is not quite what I expected (see attached screenshots of MAX).

    I am providing an external 5V to the amplifier, so no load can expect approximately 3V from the amp - it works OK. With a load applied, I expected to see a constant voltage drop, however I seem to have become unstable, with decrease in voltage.
