摘　　要：随着城市化进程的加快,地铁线路逐年增加,地铁车辆服役过程中的动力学问题和车轮磨耗问题不断涌现。为了探究传统的轴箱外置型和轴箱内置型地铁车辆的动力学性能及轮轨磨耗差异,使用SIMPACK建立了轴箱内置型和轴箱外置型两种地铁车辆模型。结合线路运行条件和车辆结构特点,根据EN 14363:2016标准分析了两种车辆在直线、小半径曲线和大半径曲线线路条件下的车辆动力学性能,以及车辆的静态抗扭曲性能;利用Jendel磨耗模型对轴箱内置和轴箱外置地铁车辆的轮轨磨耗进行了仿真分析。结果表明:两种车辆模型在直线和曲线上的动力学性能均满足标准要求,在两种扭曲线路上的抗扭曲性良好。与轴箱外置型车辆相比较,在直线线路上,轴箱内置型车辆的车体横向加速度最多降低16%,车轮导向力最多降低41%;在小半径曲线线路上,横向加速度可降低8%,车轮导向力可降低49%,车轮磨耗量降低40%,钢轨磨耗量降低37%;在大半径曲线线路上,横向加速度可降低20%,车轮导向力可降低38%,车轮磨耗量降低21%,钢轨磨耗量降低33%。文章研究的轴箱内置型地铁车辆符合EN 14363:2016标准,并且与传统轴箱外置型转向架相比,其车体横向加速度、车轮导向力、轮轨磨耗都得到了改善,可以为轴箱内置型地铁车辆的设计和运维提供依据。As urbanization accelerates,the number of metro lines keeps growing,and dynamic and wheel wear issues in the service of metro vehicles are constantly surfacing.In order to investigate the dynamic performance and wheel-rail wear disparities between traditional metro vehicles equipped with external axle boxes and integrated axle boxes,two models of these two types of vehicles have been established by utilizing SIMPACK.Combined with line conditions and vehicle structural characteristics,the vehicle dynamic performance of these two types of vehicles under straight line,small radius curve and large radius curve conditions,as well as the static anti-twisting performance,are analyzed according to EN14363:2016;Jendel wear model is used to simulate and analyze the wheel-rail wear of metro vehicles with an integrated axle box and external axle box.The results indicate that the dynamic performance of these two types of vehicles on straight lines and curves meets the standard requirements,and that the twist resistance on the two twisted lines is good.Compared with the vehicle with external axle box,the lateral acceleration of the carbody and the wheel guiding force of the vehicle with integrated axle box are reduced by up to 16%and 41%on the straight line;On the small radius curve line,the lateral acceleration can be reduced by 8%,the wheel guiding force can be reduced by 49%,the wheel wear can be reduced by 40%and the rail wear can be reduced by 37%;On the large radius curve line,the lateral acceleration can be reduced by 20%,the wheel guiding force can be reduced by 38%,the wheel wear can be reduced by 21%,and the rail wear can be reduced by 33%.The metro vehicle with integrated axle box studied in this paper conforms to EN 14363:2016,and compared with the traditional bogie with an external axle box,its lateral acceleration,wheel guiding force and wheel-rail wear have been improved,which can provide a basis for the design,operation and maintenance of metro vehicles with integrated axle boxes.
