摘要
绞盘在进行救援作业时推荐用其他重型通用运输车辆作为系固点。以列装部队的SX2190重型运输车为实验对象，介绍了实验的内容及方法，并对绞盘系固车后车架一牵引钩系统进行了有限元仿真分析与强度实验验证。结果表明，车架一牵引钩系统能够经受住20t的持续拉力作用，达到了设计强度。并且在最大30t持续拉力作用下，车架塑性无明显变形或破坏，只是部分区域的应力值较大，仿真计算的最大畸变能准则应力达到屈服极限值。
Heavy general transport vehicles are recommended as lashing points during rescue operations of winch. Taking 5X2190 heavy transport vehicles frame as the experimental object, this paper introduces contents and methods of the test, and gets evaluation result of the rear frame through finite element simulation and experimental validation of the real frame - towing hook system for winch lashing car.
