Health assessment of EMU traction drive system
摘要
Abstract
Health status assessment of electric multiple units (EMU) traction drive system is helpful to improve the safety and reliability of the EMU in operation. By taking EMU traction drive system as the concrete research object, a method based on fusion of fuzzy grey clustering and combination weight was proposed to evaluate the health status of the system in this paper. First of all, indexes' combination weights of each component of the traction drive system were calculated by the combination weighting method. Secondly, the fuzzy evaluation matrix of component layer's health status assessment was established using clustering coefficient of each component. Then, according to the matrix, the combination weighting method was used to calculate component layer's combination weight. Finally, the fuzzy comprehensive evaluation method was utilized to evaluate traction drive system's integral health status with a traction drive system of CRH3 EMU as an example. The results show that the proposed method combines the layered analysis model of traction drive system, and intuitive information on the health status of each index, key components and traction drive system can be obtained. Meanwhile, the health status assessment of CRH3 EMU traction drive system can also be carried out effectively.关键词
