摘要
随着舰船综合电力系统对电机转速和功率需求的不断增大,传统非导磁金属材料已难以满足大功率高速永磁电机护套机械强度要求,热塑性复合材料强度高、涡流损耗小、护套厚度也远小于金属护套,具有良好的发展前景。该文通过建立热塑性复合材料(T700/PEEK)激光加热成型过程三维温度-流体-运动多物理场耦合分析模型,考虑热塑性树脂熔化相变过程,提出预浸带截面运动速度+力学载荷边界结合局部圆柱坐标系的方法,解决了大张力载荷预浸带缠绕等效模拟难题,实现了考虑材料非线性的大张力缠绕高速电机转子复合材料护套成型工艺过程的多物理场耦合模拟。通过实验测试的温度与仿真结果对比,验证该文建立的多物理场耦合仿真模型的有效性。该研究所得结论对完善高速永磁电机转子复合材料护套张力缠绕工艺具有一定参考价值。
With the increasing demand of speed and power of integrated power system,traditional non-magnetic alloy materials have been difficult to meet the mechanical strength requirements of high-speed permanent magnet motor sheath.Thermoplastic composites have high strength,eddy current loss and sheath thickness are far less than the alloy sheath,which has good development prospects.In this paper,a three-dimensional temperature-fluid-motion multi-physical field coupling analysis model for the laser heating forming process of thermoplastic composites T700/(polyetheretherketone,PEEK)was established.Considering the melting and phase transformation process of thermoplastic resin,the method of prepreg tapes section velocity and mechanical load boundary combined with local cylindrical coordinate system was proposed,which solved the problem of equivalent simulation of prepreg tapes winding under large tensile load,and realized the multi-physical field coupling simulation of the forming process of high-speed motor rotor composite sheath with large tensile winding considering material nonlinearity.The validity of the multi-physics coupling simulation model established in this paper is verified by comparing the temperature of the experimental test with the simulation results.This study provides some useful reference for improving forming processing technique of rotor composite sheath for high speed permanent magnet motor.
