摘　　要：转向架悬挂的刚度参数直接影响到车辆的动力学性能,针对于整备状态转向架悬挂参数的测试方法,首先阐述了新型转向架参数测试台的结构及试验时转向架的受力关系;提出了基于车辆实际运行模拟的转向架悬挂三轴向刚度的测试模型,并通过运动学位姿反解得到各缸加载的控制指令,为电液伺服系统提供控制输入.并以某型车独立转向架为例,实现了转向架轴箱悬挂垂向刚度的测试,并得出了悬挂垂向刚度的特性曲线,并测定出1#轴箱垂向刚度为1.15 MN/m,2#轴箱垂向刚度为1.18 MN/m,3#轴箱垂向刚度为1.143 MN/m,4#轴箱垂向刚度为1.222 MN/m.试验结果验证了文中测试模型的正确性,测试值与理论值对比分析进一步说明试验台测试结果准确可信.Dynamic performance of vehicle is directly affected by the stiffness parameters of the bogie＇s suspension parameters. Aiming at the test method of bogie＇s suspension parameters, which were in the preparation conditions, the structure of the new test bench and the force of the bogie when it was tested were described. The 3-axis stiffness test models for the bogie were put forward, and were based on the actual operation simulation of the vehicle. The control instructions of the actuators were obtained via inverse displacement analysis, which supplied the control in- put for the electro-hydraulic servo system. While considering one specific vehicle bogie as an example, the test of the primary suspension vertical stiffness was completed, and the characteristic curve and value of the primary sus- pension vertical stiffness were derived. It was discovered that the vertical stiffness of axle box #1 was 1.15 MN/m, the vertical stiffness of axle box #2 was 1.18 MN/m, the vertical stiffness of axle box #3 was 1.143 MN/m, and the vertical stiffness of axle box #4 was 1.222 MN/m. The results proved the correctness of the test model. When exami- ning the calculated results and the experimental data, the credibility and accuracy of the test results were verified.
