Vibration Testing Question

Vibration Testing Question

Vibration Testing Question

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 "mock" 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 "bonding" to the panel.

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.

RE: Vibration Testing Question

MIL-STD-810 (check http://www.dtic.mil/stinet/str/dodiss4_fields.html) provides specifications for environmental testing, but I'm not sure that's what you are looking for.  

From your query, I assume you are testing to ensure that electrical conductivity is not interrupted in a normal(?) vibration environment.

Probably, the low-frequency, high amplitude vibration environment found on helicopters would be your worst case.  Perhaps someone in the forum may have access to good/bad vibration levels and spectra for you.    

RE: Vibration Testing Question

What you need is a copy of RTCA DO-160-Environmental and Test Procedures for Airborne Equipment.  You can get it from RTCA Inc., 1140 Connecticut Ave N.W, Suite 1020, Washington, DC, 20036-4001, USA (of course).

White Paper – Your Construction ERP RFP Checklist
Selecting business software for a medium to enterprise-sized construction concern is extremely challenging in large part because most enterprise resource planning (ERP) suites originated in the world of repetitive manufacturing and are therefore a poor fit for a project and asset-centric business. However, midsize to large contractors need the predictable, auditable processes that ERP delivers. Download Now
