摘要
对研制的250km/h动车组用铸钢制动盘进行了盘体材料的金相组织试验、力学性能试验和热物理性能试验,还进行了制动盘1∶1制动动力试验、疲劳试验和60万km载客运用考核。
The microstructure test,mechanical properties test and thermophysical properties test for the disc material as well as the brake disc 1∶1 braking force test,fatigue test and 600 000 km passenger carrying operation examination are carried out on the cast steel brake disc being developed for the 250 km/h multiple units.
