GJB150.20A-2009 Environmental Test Methods for Military Equipment Laboratories Part 20: Bombardment Vibration Test

Vibration test is a simulation of various vibration conditions in the laboratory to examine the impact of vibration on the product. The purpose of vibration testing is to determine whether a product can withstand external vibrations or self generated vibrations during transportation, use, and operation, without being damaged and able to maintain its original performance, achieving the expected lifespan and reliability.

There are many items included in vibration testing, which can be classified into sinusoidal vibration testing, random vibration testing, mixed testing (sinusoidal+random vibration testing, random+random vibration testing, artillery vibration testing, etc.), beat frequency testing, etc. based on the nature of the load loaded in the test.
