混动汽车机电耦合系统效率影响因素分析及优化研究OA北大核心CSTPCD
Analysis and optimization of factors influencing the efficiency of electromechanical coupling systems of hybrid electric vehicle
研究了机电耦合系统传动效率主要影响因素,分析了机电耦合系统机械损耗、电控损耗和电机损耗3部分损耗的组成及影响因子,分析得出机械损耗与摩擦条件密切相关,电控损耗包括IGBT损耗和FWD损耗,二者均受开关频率影响,电机损耗与磁场强度和电流大小有关.提出通过改善摩擦条件和调整IGBT开关频率来优化机电耦合系统综合效率,开发了机电耦合系统传动效率测试台架,依托自主开发的测试台架分别测得了纯电模式下机械损耗、电控损耗和电机损耗在不同工况下的结果,分析了机械…查看全部>>
This paper studies the main factors affecting the transmission efficiency of the electromechanical coupling system and analyzes the influencing factors for the mechanical loss, electronic control loss and motor loss. Our analysis shows the mechanical loss is closely related to the friction condition. The electronic control loss includes IGBT loss and FWD loss, both of which are affected by the switching frequency. Motor loss is related to magnetic field stre…查看全部>>
