摘　　要：基于ADAMS/Rail模块,建立独立车轮转向架车辆和传统轮对转向架车辆的仿真模型,并比较两者的曲线通过性能。独立车轮轮重减载率和弹簧振动在曲线通过时比传统轮对式更快趋于稳定状态,磨耗水平较低,适合城市轨道交通,但容易向一侧偏转;独立车轮脱轨系数较传统轮对大,建议加大对独立车轮新型转向架的研究力度。Based on the ADAMS/Rail module,the simulation models of ve-hicles with independent wheel bogies and conventional wheelset are established respectively.Compared with conventional wheelset,wheel unloading rate and spring vibration of independent wheels in curve passing tends to steady state rapidly,and the wear level is lower,indicating that independent wheels are suitable for urban rail transit.However,derailment coefficient of vehicles with independent wheels is bigger than that with conventional wheelset since independent wheels are easy to one side deflection.It is suggested that the re-search for new bogie of independent wheels should be strengthened.
