摘要
Skoda 15T有轨电车的端部转向架采用心盘偏置结构,心盘偏置会影响端部转向架前后轮对的轮轴横向力分配,进而影响车辆的曲线通过性能.为探究端部转向架心盘偏置的合理距离,基于整列车辆的轮轴横向力因子最小原则,根据有轨电车通过圆曲线受力分析模型推导轮对横向力因子达到最小值时的端部转向架心盘偏置的最优距离.使用动力学仿真分析转向架心盘偏置距离对车辆曲线通过性能的影响.仿真结果表明,当端部转向架心盘处于理论推导的最优偏置距离时,整列车辆的轮轴横向力因子和脱轨系数达到最小值,车辆曲线通过性能达到最优.
Abstract
The Skoda 15T tram utilizes a center plate offset structure in the end bogie,impacting the lateral force distribution between the front and rear wheelsets of the end bogie.This,in turn,influences the vehicle's dynamic performance on curves.To explore the optimal distance for the center plate offset in the end bogie,this article relies on the principle of minimizing the wheelset transverse force factor of the entire vehicle.According to the force analysis model of the tram when negotiating a circular curve,the deduced optimal distance of the end bogie center plate offset is determined when the wheelset transverse force factor reaches the minimum value.This article also employs a dynamic simulation to analyze the impact of the center plate offset distance on curve negotiation performance.The simulation results indicate that when the center plate of the end bogie is at the theoretically derived optimal offset distance,the lateral force factor and derailment coefficient of the entire vehicle reach their minimum values.This configuration results in an optimal curve negotiation performance for the tram.
