GJB150.16A-2009 Environmental Test Methods for Military Equipment Laboratories Part 16: Vibration Test
The reciprocating motion of an object or particle relative to its equilibrium position is called vibration. Vibration can be divided into sinusoidal vibration, random vibration, composite vibration, scanning vibration, and fixed frequency vibration. The main parameters for describing vibration are amplitude, velocity, and acceleration. Tests conducted on physical objects or models of vibration systems on site or in the laboratory. A vibration system is a mass elastic system excited by a vibration source, such as machines, structures or their components, organisms, etc. Vibration testing originated from the aerospace sector and has now been promoted to various industrial sectors such as power machinery, transportation, construction, as well as environmental protection and labor protection. Its application is becoming increasingly widespread. Vibration testing includes response measurement, determination of dynamic characteristic parameters, load identification, and vibration environment testing.
