动车组动力学响应测试从车辆响应的角度检测线路状态,测试车辆在线路不同区段的运行稳定性和运行平稳性,指导线路精调。动力学响应超限指标与线路缺陷类型的关系比较复杂,既有一定的对应关系,又不是一一对应。通过对多条线路的联调联试结果进行分析,总结各指标超限的原因和精调措施,解析对应关系的规律,更有效地指导线路精调。
EMU dynamic response test from the perspective of vehicle response to detect the line state, the test vehicle in the different sections of the road running stability and smooth operation, guiding the line fine-tuning. The relationship between the kinetic response overrun index and the line defect type is rather complicated, not only corresponding to one another but also not one-to-one correspondence. Through the analysis of the results of the joint debugging of multiple lines, the paper summarizes the reason of the overrun of each index and the measures of fine adjustment, analyzes the law of correspondence, and guides the fine adjustment of the line more effectively.
