Abstract

In order to improve the comprehensive performance of switched reluctance motor (SRM), a multi-indicator synchronous optimization design method based on the multiphysical field coupling characteristics of SRM is proposed. First, constraints considering vehicle’s actual driving conditions are established by constructing motor drive system and vehicle dynamics system. Second, finite element analysis (FEA) is constructed to analyze the electromagnetic properties based on its actual operating region. Considering the magnetic-thermal coupling characteristics, a thermal field analysis model is established, and the temperature distribution of SRM is obtained. Subsequently, key performance indicators are identified based on the characteristics of SRM, and the influence of design variables on these indicators is studied, leading to the proposed multi-indicator synchronous optimization design method based on the multiphysical field coupling characteristics. Finally, a comparative analysis and experimental validation of the SRM performance indicators before and after optimization are carried out, demonstrating the effectiveness of the proposed optimization design method.

考虑多物理场耦合的车用开关磁阻电机多指标同步优化

为了提高开关磁阻电机的综合性能，提出了一种基于开关磁阻电机多物理场耦合特性的多指标同步优化设计方法。首先，通过构建电机驱动系统和车辆动力学系统，建立考虑车辆实际行驶条件的约束条件；其次，根据其实际工作区域，构建有限元分析（FEA），分析其电磁特性。考虑SRM的磁热耦合特性，建立了SRM的热场分析模型，得到了SRM的温度分布。随后，根据SRM特性确定关键性能指标，并研究设计变量对这些指标的影响，提出基于多物理场耦合特性的多指标同步优化设计方法。最后，对优化前后的SRM性能指标进行了对比分析和实验验证，验证了所提优化设计方法的有效性。
