Why bother with vibration testing? - Electronics Weekly

When engineers ask me why companies bother with shock and vibration testing, there are three main reasons that I always cite: reliability; functionality and structural integrity. You want the equipment to be reliable, to continue to function correctly and – to put it bluntly – you don’t want it to fall apart.

FEMCI Book - Miles' Equation

Miles' Equation Does NOT Work in Reverse - Accelerations cannot be determined during random vibration testing using Miles' Equation. An upper bound on loads can be calculated using the 3-sigma value, but that's about it. In other words, a part designed to 3-sigma equivalent static loads will survive a random vibration test.

Vibration and Shock Environmental Test Types - Shock and

Vibration and Shock Environmental Test Types. Simulated vibration environments in the laboratory are used to qualify products during design, to test products against standards, e.g. Mil-std 810 etc., to locate sources of noise, e.g. in squeak and rattle testing and for stress screening, where the failure modes in components are precipitated.

What is Random Vibration Testing?

Aside from testing a product to find and dwell at its resonance frequencies to determine fatigue life, one might also use sine testing to determine damage to equipment. A sine sweep prior to any shock or random vibration test will identify the dominant resonances of the tested equipment. Repeating the sine test after

Environmental stress screening - Wikipedia

Environmental stress screening (ESS) refers to the process of exposing a newly manufactured or repaired product or component (typically electronic) to stresses such as thermal cycling and vibration in order to force latent defects to manifest themselves by permanent or catastrophic failure during the screening process. The surviving population, upon completion of screening, can be assumed to

Vibration Testing Standards | List of Standards & Applications

The typical aircraft random vibration test profiles are between 30 minutes and 6 hours per axis, with 3 hours being a common choice in the absence of specific knowledge of the transportation profile. Often truck random vibration profiles are testing in conjunction with aircraft profiles to represent transport before and after air transport.

What is a Vibration Resonance? - Vibration Testing, Shock

Some random vibration test specifications such as RTCA DO-160 (Environmental Conditions and Test Procedures for Airborne Equipment) require a sinusoidal vibration resonance scan before and after the test along each axis. Any significant change in the resonance scan results could be sign of damage or product failure.
