【正文】 the feedback control of the system was achieved by using purity as the target last, with the developed modal test system, multipoint coordinated excitation modal test was conducted on the secondary suspension model car, and the natural frequency and vibration mode of the model car was obtained. Comparing the result with the natural frequencies and vibration modes obtained via Ploymax parameter identification method, it indicated that the results of the two tests are in accordance with each other within an acceptable error, but the multipoint coordinated excitation method got a higher modal purity of each vibration mode.【關(guān)鍵詞】機(jī)車振動 模態(tài)分析 模態(tài)純度 多點(diǎn)協(xié)調(diào)激勵 鐵道車輛【英文關(guān)鍵詞】lootive vibration modal analysis mode purity multipoint coordinated excitation railway vehicle【目錄】機(jī)車車輛多點(diǎn)
