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.
With the increase of passenger space, the installation space of vehicle brake system decreases. It is a contradiction between the volume of the brake cylinder of urban rail transit vehicles and the braking force demand. Aiming at the design of the brake cylinder volume requirement of urban rail transit vehicles, ARIZ algorithm is used to define the mini-problem, which it is necessary for the engineering system is unchanged while the assembly demand of the brake cylinder on the bogie is retained, and the braking effect of the braking system is effectively improved. Based on the mini-problem, the ideal-final solution and physical contradiction were defined, and the expanded substance field resources were used to solve the problem, in which 13 high-quality solutions are obtained. Combining all the innovative solutions, a new design method of brake cylinder system is designed for gearbox. Finally, the feasibility of the scheme is achieved.
