Test question of impact frequency

Hi all:

I'm trying to get the natural frequencies of some frames my company designs and I was wondering if there was a simple way to get this to the impact of the sample test of vi and display? Currently, I work with SVXMPL_Impact Test.vi and SVXMPL_Advanced Impact Test.vi and I am running Labview 2010 with the sound and vib add on.

Andy

Hi andy,.

It seems that these example programs to find the frequency of the pulse signal. You can use the same .vi SVFA FFT (Mag Phase) spectrum used in the research of the frequency to find the frequency of the response signal. Once you have this signal, you can use the spectrum SVFA cutting-edge research to read the natural frequency from the frequency data.

    Hello

    You'll be lucky if anyone from Toshiba are reading this. ;) I'm kidding!

    I read a lot of content on the page of Toshiba Europe, but something like that is not available or information on TCEs. It's something special for authorized service partners?

  • Satellite A200-1TS - question on the frequency of the DRAM

    Hello

    I have the Satellite A200-1TS with bios vista x 64 vers.2.60 and I upgraded the RAM with (slot 1 and slot 2) each module 2 GB 800 MHz, and work, but the cpu - z program is detect the TIMINGS TABLE frequency is what is good for 800 MHz to 400 MHz, but the DRAM frequency is always working with 332,5 MHz (667 mhz).

    What is the problem? Can I do something to work at 400 MHz?

    Hello

    I think that the RAM works on 333 MHz because it s always according to the FSB of the processor.
    It seems therefore that the CPU has a 333 MHz FSB and RAM also runs on this speed.

    If you have any other questions, please let us know! :)

  • Newbie on impregnation test question to

    I pray to God that I am not violating any term request this. I received an invitation from dipping to participate with a link to a survey. I finished it and after, he said I'm probably would participate. It was 3 days ago and I have not heard anything since. Having never done this before, I'm insanely curious if there is normally a 4-5 day wait... If I did something wrong or if I just wan't selected. Please understand that I was eager to hear something that I want to participate!

    I understand that it is taboo to discuss the test, so I wasn't sure if just ask me these questions would create problems. Yet once again, I never did (only got my Photon 10 months) so I do not know the procedure.

    If this post is prohibited, mods/admin please delete or let know me, and if I can, I'll remove it.

    Thank you!

    You have nothing to fear. There is a bit of wait times with different parts of the test of impregnation.

    Just keep in mind that soaking tests are like Fight Club;

    And the first rule of Fight Club?

    All in good time.

  • Questions about the frequency step response

    Hello

    I use the Signal Express 3.0. I'm not clear on the transfer functions in step of frequency response with different modes of calculation of the average. What I got from the help file is this H (f) = Sab (f) /Saa (f) which is cross the frequencies on the spectrum auto where is the pulse and b the signal response signal. When the mean quadratic value is used, I wonder if the transfer function becomes greatness of cross spectrum divided by the magnitude of the spectrum of the car. When an average of vector is, everthing is used in complex numbers. He averaged temporal signals, frequency domain signals, or the results of transfer functions?

    Thank you very much.

    The algorithm to calculate the spectrum is the same in both modes.  However, the method of calculation of the average can have a huge impact on the outcome.  Mean quadratic value is performed on the spectrum itself, after the calculation.  Vector averaging is done on the input signals before the calculation.  With an average of vector signals must be consistent (have the same phase) or the result will be bad due to the signal being on average by far.

    Could at least spell my name correctly?

    Say that the improbability is low is not at all like saying that it is impossible. It would be unlikely to switch the 19 heads in a row, but the probability that the next draw is still 50-50.

    I agree that the correct answer is B, but like many in questions that I saw, the answer has doubts and should be rewritten.

  • Before the test Questions Captivate 8

    Hello

    I use Adobe Captivate 8 and I've added a question 3 before the test.  I edited the first issue and made my questions multiple choice that I went to the second issue of pre-test and that of prestest #1 appears in the pre-test, #2 and #3.  Why - what is duplicate my original question on all the other before the test?  I have no idea how to get rid of on pre-test #2 and #3.

    Any help would be greatly appreciated.

    So weird. Then try: delete preferences. Close the project, locate the CleanPreferences file that is appropriate for your system in the subfolder "Utils" of the captivate installation folder and run it. Then restart Captivate. Are you running it as an administrator (if you are using Windows)?

  • Pre-test Question slides crashing my project

    Hi guys,.

    Here is my weekly 8 Captivate question! (I learned to love how it should still be in beta...)

    I want to insert a question slide multiple choice, as a pre-test, but whenever I click on OK, captivate crashes just downright. None of the error messages or the bug report dialog appears, he just died.

    I have restarted the machine several times, and only made sure no other software is running.

    I really want to like Captivate, I do it, so I hope someone can shed some light on this issue, one of the many questions I have met since the purchase of this product.

    Here's my spec;

    Mac Pro (mid-2010)

    2 x 2, 66 GHz 6-core Intel Xeon

    24 GB RAM

    ATI Radion HD 5770 1024 Mb

    OS X Yosemite 10.10.5

    And i've got to always available storage.

    Help, please! Thanks for your time.

    Karl

    * Update - installed the 8.03.290 patch. Now, ALL blocks Captivate! I have no problems with other products Adobe, or any other application.

    You can try if this also occurs in a new project? In this case use the CleanPreferences, please.

  • Exam test question help

    Hello...

    The question you entered he says"... which of these applications potentially returns more than two lines. »

    As noted the explanation in the answer, C & D returns more than two lines if the table has more than two lines. While the question is written, C & D should be the answer. However, the explanation suggests that the A & B are the correct answers.

    If you have faithfully reproduced everything, what we have here is a combination of wrong answers. I'm shocked, shocked, I say to find a practice test with an error. :)

    Someone screwed up. If we assume that the explanation is correct, then the question should have read something like "+...". which of these queries will never return more than two lines. + »

    That said, if it is a commercial practice test, you really should not reproduce here because of copyright issues. At least, it is not a question of real exam which would also lead to questions of violating the agreement of the OCP candidate and potential loss of certification.

  • Setting a conditional Action for pre-test questions: skip content slides

    OK boys and girls, let's see if this is even possible in a course of SCO, or if this solution multi-SCO (which means I'm toast, because we do not have the multi-SCO aggregator)?

    I want to implement a prescriptive pre-test. In my ideal world, the answers to each individual question would either enable or disable the content related to the question slides. If the user passes the pre-test, they might opt to skip the prescriptive stuff and complete the course. If the user fails the pre-test, they should consult the active content.

    Is it still possible in a unique world of SCO?

    Justenuf

    Will try to explain how I would try to handle this use case, but I didn't try it!

    • For the first condition, you already have a system variable which can be used in conditional actions to check if the user has passed the pre-test. If you use ordinary question slides, cpQuizInfoPassFail will be set to 1 if it is adopted, the value 0 as var is full only after the last slide in the question. If you use slides before the test, you will need to create a variable user, which you can fill with a tip action, based on the value of cpQuizIntoPretestPointsscored or cpQuizInfoPretestScorePercentage.
    • To follow the questions they did correctly, you must create a variable user for each slide of the issue, default = 0. Based on the system variable cpQuizInfoLastSlidePointScored, which is completed after each slide of the question, you can switch the variable user of the slide of the previous to 1 question if this sys var is greater than 0. This can be done by an action at the entrance to each slide of the question. You will need such action on enter also immediately after the last question slide (maybe on a blade of results, where you can also put the appropriate button to switch the content slides, or offer the possibility to go back).
    • For each slide content you will need another (conditionala tip enter action. Condtion will check the value of cpQuizInfoPassFail (or the equivalent for the slides before the test) AND the value of the var related to this question slide. If both are positive, ignore the slide (go to the next slide), if not, just stay on the slide. That action will be the same for all the slides in content related to a question. But another question, you will need a duplicate, because another user variable will be there. If you use CP7, this is an excellent example for joint actions.

    Hope this helps a bit, sorry that I am so busy.

  • VCP Test question

    Before VI 3.5 VCB requirements were a machine running windows. Today, you can run VCB as a virtual machine. My question is, the test has been updated to reflect these changes.

    Even with FC storage, you can run VCB in "hot add" mode in a virtual machine, for example there is a "nbd m" switch for the command vcbmounter - data is transferred through the stack of I/O of ESX servers in the virtual machine, so it is not the same as running on a physical machine with the transfer of the data being based entirely on the SAN , but it still works

  • Question on the frequency of the RAM - Tecra M5-384

    Hello, everyone!

    I am considering buying a Toshiba Tecra M5-384, but there is one thing that concerns me - system memory. In the specifications , it is written that the technology of system memory is DDR2 533 MHz.

    This means that I can't use DDR2 677 MHz?

    Hello

    I am not a technician, but in my opinion, you should always use tested and absolutely recommended hardware components. That s my general opinion.

    You can use module more fast but be realistic. Do you really think this will help? AFAIK slower module will be running 533 MHz. The best thing you can do is to increase the RAM to max level using modules of memory live recommended. On this way, you will be sure that everything will be ok.
