Optimization of Performance Index of Composite Brake Shoe of Railway Freight Car
Based on the synthetic brake shoe industry standard,this paper puts forward suggestions for optimizing the performance index of synthetic brake shoe in China,promotes the improvement of synthetic brake shoe formula and manufacturing process,solves the problems of frequent tile change and low reliability,and meets the needs of railway freight cars.By investigating the field use of synthetic brake shoes of railway freight cars,the main problems of the synthetic brake shoes,such as poor wear resistance,low reliability and discrete friction coefficient,encountered in the field use,were understood,and the causes and solutions of the problems of the synthetic brake shoes,such as cracked,broken block and metal inlaying,were analyzed,and the physical and mechanical performance indexes were compared with those of similar foreign products.Some suggestions for optimizing the performance index of synthetic brake shoe based on《Brake Shoe for Rolling Stock—Part 1:Composite Brake Shoe》(TB/T 3104.1-2020)are put forward.
