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。
Through the detection of the wheel pair, describes the method of spot detection of the running status of the rail vehicle on line. Based on Timoshenko beam finite element orbit-vehicle vertical coupling model, the on-line continuous test of wheel tread abrasion was simulated. The simulation results truly reflect the actual test phenomenon.
