摘要
新型高度集成化液压电机泵将电机和液压泵的功能高度融合,具有结构紧凑、能量转化效率高等优点,在航空领域具有广阔的应用前景和研究意义。然而,液压电机泵中电机的发热及冷却一直是困扰人们且需要解决的难题。本文通过研究液压电机泵电机的发热机理,建立液压电机泵的流场、电磁场及温度场的数学模型;通过数值模拟研究液压电机泵的流场、电磁场及温度场的分布及耦合影响因素,发现自冷却流道周围流体和该流体位置所对应的壳体温度会有所降低。本文对应用于航空领域的高度集成化液压电机泵的设计及自冷却方式具有一定的指导意义。
The new highly integrated hydraulic motor pump highly integrates the functions of the motor and the hydraulic pump.It has the advantages of compact structure and high energy conversion efficiency,and has broad application prospects and research significance in the field of aviation.However,the heating and cooling of the motor in the hydraulic motor pump have always been a problem that needs to be solved.By studying the heating mechanism of the motor in the hydraulic motor pump,a mathematical model of the flow field,electromagnetic field,and temperature field of the hydraulic motor pump was established.Through numerical simulation,the distribution of the flow field,electromagnetic field,and temperature field of the hydraulic motor pump and the coupling influencing factors were studied.It was found that the temperature of the fluid around the self-cooling flow channel and the corresponding temperature of the shell would be reduced.This provides some guidance for the design and self-cooling method of highly integrated hydraulic motor pumps that can be applied in the aviation field.
