轮缘厚度对地铁直线电机车辆曲线通过性能影响研究
Study on Influence of Rim Thickness on Curve Passing Performance of LIM Metro Vehicle
摘要: 为了研究不同LM踏面轮缘厚度对地铁直线电机车辆曲线通过性能的影响，本文考虑直线电机的电磁力作用，通过建立联合仿真的机电耦合直线电机车辆动力学模型，研究分析了采用LM、LM-31、LM-29、LM-27四种不同轮缘厚度踏面的车辆通过小半径曲线时动力学性能指标及电机气隙的变化规律。研究结果表明：直线电机车辆通过曲线时，轮缘厚度对脱轨系数和轮轴横向力影响显著，对轮重减载率、轮轨垂向力和电机气隙影响不大。小轮缘厚度的LM-27踏面可以降低车辆曲线通过脱轨系数约15.5%，但会使轮轴横向力增加15%~20%。
Abstract: In order to study the different rim thickness of LM tread on the curving performance of linear induction motor (LIM) metro vehicle, this paper considering the electromagnetic force of LIM, and establishing the electromechanical-coupled dynamic co-simulation model of LIM metro vehicle, analyzes the dynamic performance and air-gap changes of LIM vehicle with four tread of LM, LM-31, LM-29, LM-27 when passing small radius curve. The results show that the influence of rim thickness on the derailment coefficient and Wheel-axle lateral force is significant when LIM metro vehicle passes the curve, and has little effect on the rate of wheel load reduction, wheel-rail vertical force and air-gap of LIM. The small rim thickness LM-27 tread can reduce the derailment coefficient of LIM metro vehicle when passing curve by about 15.5%, but it will increase the lateral force of wheel-axle by 15%~20%.
