轨道路基动力响应液压激振系统仿真

摘要

为了研究轨道路基动力响应,对所建立的可模拟列车荷载的液压激振系统进行了AMESim建模与仿真.对所设计的动、静压腔液压激振系统分别进行建模与仿真,验证各自的可行性；然后封装所有模型构建整个液压激振系统模型,并对其进行仿真.结果表明,所设计的液压激振系统能满足设计指标要求.%To research the track ground dynamic response, modeling and simulation were done hy AMESim software for the hy-draulir excitation system, which was established to imitate the vibration of the moving. The feasibilities of the devised dynamic hydraulic excitation system and static hydraulic excitation system were verified, which were modeled and simulated respectively. All the models were packaged to build thf whole model of the hydraulic excitation system, which was also simulated. The results show the designed system meets the design requirements.
