摘要
介绍三合一电驱系统结构,以电驱系统可靠性试验为对象,基于加速寿命原理,选定适用于三合一系统电子电气可靠性考核技术指标;结合电驱系统应用状况,以电机可靠性考核标准定义的循环工况为蓝本,衍生适应于该项目的可靠性循环工况,使三合一电驱系统的验证更为合理。
The structure of integrated electric drive system was introduced.The reliability test of electric drive system was taken as the object.Based on the accelerated life principle,the technical index of electrical was chosen as electronic reliability assessment for the integrated system.With the combination of application status of electric drive system and cycle condition defined by the motor reliability assessment standard as the blueprint,technical index that is suitable for the three-in-one electric drive system is acquired.The result shows that the new index is superior and more reasonable to the verification of the integrated electric drive system.
