机车车辆轴箱定位装置的试验
|
摘要
为对机车车辆轴箱定位装置进行系统的力学性能试验,简要分析了一种轴箱定位装置的结构与原理,设计了轴箱定位装置单件加载与系统加载2种试验方案并进行分析比对,重点通过系统加载试验方案来研究轴箱定位装置的刚度和疲劳性能。试验结果表明:试验设计与实际工况一致,系统试验更能准确反映出轴箱定位装置的力学性能,试验数据显示该结构轴箱定位装置纵向刚度呈非线性,横向刚度和垂向刚度呈线性,疲劳性能满足装车要求。
In order to test the crankcase location device of locomotive and vehicle systematically, the structure and principle was analyzed, and the two test scheme of single piece loading and system loading was designed and compared, focusing on research of crankcase location device stiffness and fatigue performance for system loading scheme. The test result showed that test design was coincide with practical conditions, and the system test could represent the mechanical properties more accurately. And the test data showed that longitudinal stiffness of the crankcase location device was nonlinear, while the vertical and horizontal stiffness were linear, and the fatigue performance satisfied the on-board requirement.
