As the world of transportation keeps moving toward greater electrification, the main design objectives in terms of power density and efficiency of system components are becoming increasingly important. Meanwhile, transportation applications are also very safety critical. The extra stresses being seen by important components, such as electrical machines (EMs) and their insulation systems, to achieve the required performances, are accelerating the degradation of components, making them less reliable and shorting their lives. In general, lifetime consumption and degradation of components, such as for insulation systems of EMs, is still assessed through statistical methods (i.e., recording the number of imposed cycles until failure of a built prototype). This is a very timeconsuming and expensive process. In the mobile applications, such assessments can be the major bottleneck in the development timeline of an electrical product, especially for certification.

面向可靠性的电机设计：机器绝缘系统的设计过程必须不断发展

随着交通世界不断朝着更电气化的方向发展，系统组件的功率密度和效率方面的主要设计目标变得越来越重要。同时，交通应用也非常安全。重要部件（例如电机 (EM) 及其绝缘系统）为实现所需性能而承受的额外应力正在加速部件的退化，使其可靠性降低并缩短其使用寿命。一般而言，组件的寿命消耗和退化，例如 EM 的绝缘系统，仍然通过统计方法进行评估（即记录所施加的循环次数，直到构建的原型出现故障）。这是一个非常耗时且昂贵的过程。在移动应用中，
