Abstract

Aiming at the problem of reducing the instantaneous noise of vacuum circuit breaker closing, the noise reduction system for rail transit vehicles is innovatively designed by using TRIZ theory. Through function analysis and cause-effect chain analysis, this paper finds the root cause of the problem, solves the problem and puts forward the scheme by establishing the technical contradiction, physical contradiction and su-field model, and finally puts forward the design of the noise reduction system, so as to provide a theoretical basis for the development of subsequent products.
