摘要在分析高速动车组牵引传动系统组成结构及工作原理的基础上,建立了牵引传动系统可靠性框图模型。在此基础上,依据系统可靠性理论和京津城际、武广高铁中CRH3型高速动车组牵引传动系统故障统计数据,推导并证明了CRH3型高速动车组牵引传动系统各部件的可靠性规律,给出了可靠性指标的计算方法,分析计算了京津城际和武广高铁中CRH3型高速动车组牵引传动系统各部件的可靠性指标。基于CRH3型高速动车组牵引传动系统可靠性框图模型,结合各部件的故障率和可靠度,评估了京津城际和武广高铁中CRH3型高速动车组牵引传动系统可靠性。研究结果为CRH3型高速动车组牵引传动系统各部件的安全运用、维护维修提供了依据。

Abstract：Based on the structure parameter and operating principle of the traction drive system for high-speed electric multiple units (EMUs), the reliability block diagram(RBD) models of traction drive system are established. According to the theory of system reliability and the fault statistic datum of the traction drive system in CRH3 high-speed EMUs which running in Beijing-Tianjin and Wuhan-Guangzhou high-speed railway, the law of reliability about components in the traction drive system are proved. At the same time, the methods of calculation about reliability evaluation indexes are given, the fault rate and the reliability of the various components are calculated. Based on the RBD model of the traction drive system, the reliability of the whole traction drive system in Beijing-Tianjin and Wuhan-Guangzhou high-speed railway are evaluated. The research results provide reference for safe utilization and maintenance and repair of the traction drive system of CRH3 high-speed EMUs.
