考虑磁致伸缩效应的电机应力数值仿真与实验
Numerical Simulation and Experimental Research on Stress of Motor Including Magnetostriction Effects
摘要
Abstract
Magnetostrictive effect of silicon steel of stator core is one of the main sources to produce noise and vibration. This paper established electromagnetic-machine coupled numerical model and utilizes finite element analysis software to calculation, and the analysis of the effect on the stator silicon steel sheet caused by magnetostrictive force and electromagnetic force was separately carried out. Numerical simulation results show that magnetostrictive force is the main source of stress in the motor stator structure, the low frequency of vibration is single and double supply power frequency. According to the simulation, motor rotor was removed to ensure the main magnetic circuit through motor stator, motor stator surface vibration signal was collected and analysed by vibration measurement equipment, the simulation results were verified. Wherein calculation theory and experimental methods used have important guiding significance to analyze the impact of magnetostrictive effect on stator vibration and noise, it has a certain academic significance for motor noise reduction research process and the reference value.关键词
