铁路牵引钩耦合器的失效分析（英文）
|
摘要
本文对欧洲和其他国家广泛使用的铁路牵引钩连接器进行了故障分析。对使用中的一些失效耦合器进行了无损测试,以确定耦合器的关键区域。牵引钩耦合器用于连接相同的钩耦合器或自动耦合器。讨论了连接类型对耦合器强度的影响。采用有限元方法进行了数值应力分析,利用临界平面法等多种方法对不同条件下耦合器的疲劳寿命进行预测。通过实验结果验证了所提出的疲劳标准和疲劳寿命预测以及静态数值分析的结果。
Failure analysis of railway draw-hook coupler was carried out. The nondestructive testing method was undertaken on some failed couplers in service to designate critical areas of a coupler. Draw-Hook coupler is used to connect with the same hook coupler or automatic coupler. The influence of each connection types on the coupler strength in this study was discussed. A numerical stress analysis using FEM was performed, and many approaches including critical plane approach were carried out on fatigue life prediction of coupler under different conditions. The results of the proposed fatigue criterion and fatigue life predictions, as well as static numerical analysis, are validated with experimental results.
