摘　　要：对某CRH1动车组的车轮外形测量及磨耗跟踪测试,并分析其轮缘厚度与等效锥度等主要参数,设计了LMD型薄轮缘踏面。利用多体动力学软件建立CRH1型动车组系统动力学模型,对LMD型薄轮缘踏面分别从轮轨关系、车辆稳定性和平稳性动力学性能进行分析并与LMD原型踏面对比。结果表明:LMD型薄轮缘踏面在运用过程中维护成本降低,并且动车组的各项动力学指标均符合运行安全的要求。Based on the measurement of wheel profile and wear tracking test of a CRH1 EMU,and analysis of the main parameters such as flange thickness and equivalent taper,then the thin wheel treads of the LMD series were designed.By means of dynamic software,it is comparatively analyzed for the original profile and LMD thin wheel flange tread on the following aspects,including vehicle critical speed,the lateral stability of the frame,and the stability of the vehicle body.The results show that the economy of LMD thin wheel flange tread has a great improvement,and the dynamic indexes satisfy the operational requirements.
