摘要 根据Matlab/Smulink建立客车两种垂向振动模型:具有动力吸振系统以及具有半主动控制系统,分4种状态:时速分别为100km/h、200km/h时,短波激励波长10m,长波激励波长50m,用变步长四阶龙格—库塔法进行仿真。在时域内对比仿真结果,得出阻尼开关的半主动控制在隔振方面优于动力吸振器。 Two kinds of vibration system made for railway passenger car are set up based on Matlab/Smulink, one is equipped with a vibration absorber system, another is equipped with a semi - active vibration isolation system. According to four states which are the short -wave 10m, the long -wave 50 m in two velocity 100km/h,200km/h respectively, using ode45 to simulate. In the end, comparing the results in time - series, we draw the conclusion that the semi - active isolation system dynamic vibration absorber is better than the vibration absorber system in railway passenger car system.
