Vibration Testing Question

[jobeth]

I am working in aerospace connetcor development (Tyco Electronics - US engineering) and I have a special vibration test I want to complete. It consists of ARINC connector shells attached to a &quot;mock&quot; airframe panel by using captive threaded fasteners. The objective is to evaluate the threaded fasteners for a low electrical resistance path between the shell and the panel. They call this electrical &quot;bonding&quot; to the panel. <br><br>The problem is I want to do a vibration test using a test signature that is meaningful using test levels that are realistic for a typical airframe panel. I am not sure where to find a test specification for guidance or test recommendations? Do you have any advice? Thank you in advance. Bill B.&nbsp;&nbsp;&nbsp;&nbsp;<br><br> <p>William H.

MIL-STD-810 (check <A HREF="

provides specifications for environmental testing, but I'm not sure that's what you are looking for.&nbsp;&nbsp;<br><br>From your query, I assume you are testing to ensure that electrical conductivity is not interrupted in a normal(?) vibration environment.<br><br>Probably, the low-frequency, high amplitude vibration environment found on helicopters would be your worst case.&nbsp;&nbsp;Perhaps someone in the forum may have access to good/bad vibration levels and spectra for you.&nbsp;&nbsp;&nbsp;&nbsp;

What you need is a copy of RTCA DO-160-Environmental and Test Procedures for Airborne Equipment.&nbsp;&nbsp;You can get it from RTCA Inc., 1140 Connecticut Ave N.W, Suite 1020, Washington, DC, 20036-4001, USA (of course).<br><br>Regards,<br><br>Nigel.<br>&nbsp;<br> <p>Nigel Waterhouse<br><a href=mailto:n_a_waterhouse@hotmail.com>n_a_waterhouse@hotmail.com</a><br><a href= > </a><br>A licensed aircraft mechanic and graduate engineer.
