Research on Computer Vibration Test System of Rotating Machinery Based on Wavelet Transform in Auto Parts Inspection

Abstract

With the development of the automobile industry, the quality of automobile parts has attracted more and more attention. In the process of automobile driving, automobile parts are affected by temperature change, vibration, impact, friction and so on, which will lead to the performance damage of automobile parts. Vibration testing technology is an experimental method which combines theoretical analysis with practical testing. Vibration testing system is mainly used to inspect the quality of automotive parts, and to provide basis for parts optimization. Wavelet change is a new transform analysis method. This paper mainly introduces the theory of vibration. Then, this paper analyses the composition of vibration testing system in automotive parts testing. Finally, computer technology is used to analyze the application of the rotating machinery vibration test system based on wavelet change in vehicle vibration test.
