【摘要】 为了探究轨道车辆轮对模态试验的方法，采用车轴轴端悬挂、车轴中部靠近辐板悬挂、车轴中间制动盘两侧悬挂、橡胶堆弹性支撑以及钢轨支撑5种约束方式对轮对模态进行试验分析，并与有限元仿真结果进行对比。分析发现，在进行轮对模态试验时应避免刚性支撑的约束方式，在采用弹性约束时，轮对的模态振型受弹性约束位置的影响较小，且轮对模态试验时的激励位置选取在轮缘与车轴端部等位置可以更加全面地激发出轮对的各阶模态信息。更多还原

【Abstract】 In order to explore the method of modal test of wheelset of rail vehicle, the wheelset modal is tested and analyzed by five kinds of restraint methods, which include suspension at the end of axle, suspension near the web in the middle of axle, suspension on both sides of brake disc in the middle of axle, elastic support of rubber pile and rail support, and its result is compared with the finite element simulation ones. It is found that rigid support constraint should be avoided in wheelset modal test. When elastic constraint is adopted, the modal shape of wheelset is less affected by elastic constraint position, and the excitation position of wheelset modal test is selected in the position of wheel rim and axle end, which can stimulate the modal information of wheelset more comprehensively.更多还原
