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。
In order to study the dynamic response of railway subgrade, AMESim modeling and simulation of the hydraulic excitation system that can simulate the train load was carried out. The dynamic pressure and hydrostatic system of the hydrostatic pressure chamber were modeled and simulated respectively to verify their feasibility. Then all the models were encapsulated to build the entire hydraulic excitation system model and simulate it. The results show that the designed hydraulic excitation system can meet the design requirements.
