马来西亚SCS动车组制动系统故障原因分析及对策

Cause analysis and countermeasures of braking system failure of malaysia SCS EMU

通过研究马来西亚SCS动车组车辆制动系统结构组成和工作原理,运用故障模式编码管理技术,对动车组制动系统运行质量进行分析。统计数据表明,制动控制模块故障占比相对较高,因此重点对制动控制模块核心部件微机控制单元进行故障模式影响及危害性分析,并针对可能的故障原因给出建议,以此提高制动系统和整车的可靠性,优化现有制动系统检修体系。

By studying the structure and working principle of braking system of Malaysia SCS EMU,the application quality of braking system of EMU is analyzed by using fault mode coding management technology.Statistical data show that the proportion of brake control module failure is relatively high.Therefore,the failure mode,effects and criticality analysis of gateway control unit,the core component of brake control module,are conducted,and suggestions are given for possible failure causes,so as to improve the reliability of brake system and vehicle,and optimize the existing brake system maintenance system.
