Optical metallographic microscope and electron-probe testing methods are used to analyze the fine crack, spall and fine cleft of U71Mn heavy rail tread.
采用光学金相显微镜和电子探针分析仪等测试方法对U71Mn重轨踏面发纹、缺损和小裂口缺陷进行了分析。
Taking this inspection of wheel tread flat 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.
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。
The troubles of tread peeling and circular wear of passenger car wheelsets are analyzed.
对客车轮对踏面剥离和圆周磨耗故障情况进行了分析,认为踏面制动形式的转向架其轮对故障以圆周磨耗为主,盘形制动形式的转向架其轮对故障以踏面剥离为主。
The result shows that the instrument can quickly inspect the radical crack and the big size tread peeling in about 10 mm field of the wheel tread,and the whole inspection processing is finished without couplant and scanning in the tread.
最后对人工缺陷轮对和自然缺陷轮对进行试验,结果表明:检测过程无需耦合剂、无需沿踏面扫查,即可快速实现对轮对踏面表面及近表面10 mm范围内的车轮径向裂纹和大尺寸踏面剥离缺陷进行检测。
