The reciprocating motion of an object or particle relative to an equilibrium position is called vibration. Vibration is divided into sinusoidal vibration, random vibration, compound vibration, scanning vibration, and fixed frequency vibration. The main parameters describing vibration are: amplitude, speed, vibration division, and acceleration. Testing of a physical or model of a vibrating system in the field or laboratory. Vibration systems are mass-elastic systems excited by vibration sources, such as machines, structures or their parts, organisms, etc. Vibration testing was developed from the aerospace sector and has now been promoted to various industrial sectors such as power machinery, transportation, and construction, as well as environmental protection and labor protection. Its application is increasingly widespread. Vibration testing includes response measurement, dynamic characteristic parameter measurement, load identification, and vibration environment testing.

Vibration test is to simulate various vibration environmental impacts encountered by products in the transportation, installation and use environments. This test is to simulate various vibration environmental impacts encountered by products in the transportation, installation and use environments, used to determine whether the product can withstand various environmental vibrations. Vibration test evaluates the resistance of components, components and complete machines in the expected transportation and use environment.

The most commonly used vibration methods can be divided into sinusoidal vibration and random vibration. Sinusoidal vibration is a test method often used in laboratories to simulate the vibration generated by rotation, pulsation, vibration (occurring on ships, aircraft, vehicles, and spacecraft), as well as product structure resonance frequency analysis and resonance point dwell verification. It is mainly divided into sweep frequency vibration and fixed frequency vibration, and its severity depends on the frequency range, amplitude value, and test duration. Random vibration is used to simulate the overall structural earthquake strength evaluation of the product and the transportation environment in the packaged state, and its severity depends on the frequency range, GRMS, test duration and axial direction. ^[2]

The reciprocating motion of an object or particle relative to an equilibrium position is called vibration. Vibration is divided into sinusoidal vibration, random vibration, compound vibration, sweeping vibration,

Trace vibration and fixed frequency vibration. The main parameters describing vibration are: amplitude, speed, and acceleration. Single-frequency sinusoidal vibration frequency is f, the amplitude is single.

If the peak value is D, the single peak value of velocity is D, and the single peak value of acceleration is.
