解决旅客运输中的运能与运量的矛盾行之有效的途径是扩大旅客列车编组。扩编后亟待解决的技术问题是制动机性能、车钩的受力强度、车轴载荷、列车纵向冲动缓冲器的容量等。从列车编组20、25、30辆的常用、紧急制动和制动距离试验看出,列车冲动均较严重,并随着扩编辆数的增加而加剧。必须采取相应措施,改善制动机性能,提高15号车钩强度和1号缓冲器的容量。
Solve the contradiction between transport capacity and transport volume in passenger transport The effective way is to expand the passenger train formation. The technical problems urgently to be solved after the expansion are the performance of the brake, the strength of the coupler, the axle load, the capacity of the longitudinal impulse buffer of the train, and the like. It can be seen from the common, emergency braking and braking distance tests of 20, 25 and 30 train sets that train impulse is serious and aggravate with the increase of vehicles. Corresponding measures must be taken to improve the performance of the brake and to increase the strength of No. 15 coupler and the capacity of No. 1 bumper.
