摘要
采用逆向工程对某进口电机进行了逆向建模,基于流体力学、传热学基本理论,考虑电机不同零部件热源的差异性以及电机运转时流体流场和温度场的复杂分布,采用有限元数值计算方法,对该电机整机温度场进行了仿真计算。通过与实验数据对比,计算误差均在0.4%内,验证了所建数值模型和采用计算方法的准确性,随后对电机内部零部件温度分布进行了分析研究。该数值模拟方法为电机温度场分析提供了简捷高效的计算方法,从而提高了电机性能的优化效率、促进国外产品的国产化。
Using reverse engineering of the imported motor reverse modeling, based on the basic theory of fluid mechanics, heat transfer, considering the motor of the differences between different parts of heat and fluid flow field and temperature field during operation the complex distribution of finite element numerical calculation method, and the machine simulation on temperature field of the motor. Compared with the experimental data, the calculation error within 0. 4%, the numerical model and calculation method was veri- fied by the accuracy of the subsequent internal parts for motor temperature distribution was analyzed. The numerical simulation method for motor temperature field analysis provides a simple and efficient calculation method, so as to improve the optimization efficiency of the motor performance, promote the localization of foreign product.
