摘　　要：通过对擦伤轮对的检测,描述了在线检测轨道车辆运行状态的布点方法。采用基于Timoshenko梁的有限元轨道-车辆垂向耦合模型,仿真了在线连续测试车轮踏面擦伤的过程。仿真结果真实反映了实际的测试现象。In this paper, the significance of inspecting the wheel/rail force when the vehicle is running on the rail is preseated briefly. Taking this inspection of wheel tread fiat as an example, this paper discusses how to arrange strain gauge on the rail, then simulates the process of wheel tread inspection on the rail based on track TBDS （Timoshenko beam on discrete） and vehicle coupling model.
