【摘要】 基于机车车辆-轨道耦合动力学理论,运用TTISIM(Train/Track Interaction Simulation)仿真软件,以横向减振器为研究对象,以机车运行平稳性指标为依据,系统分析了机车横向减振器的阻尼参数、工作状态、卸荷速度和悬挂位置等参数对于机车平稳性能的影响。仿真计算与分析结果表明:选取适当横向减振器的结构阻尼参数,对提高机车的平稳性有利;采取适当的减振器卸荷速度可以达到提高乘车舒适性的目的;横向减振器是否正常工作对机车的运行品质有较大影响,必须严格确保所有减振器的正常工作;横向减振器的悬挂位置,对于车体的运行平稳性几乎没有影响。更多还原

【Abstract】 Based on vehicle-track coupling dynamics,with simulation software TTISIM,the effects of the parameters,working condition,unloading velocity and position of lateral damper on the running performance of speed-raised locomotive were systematically investigated.Analysis result shows that it can improve locomotive riding performance to choose proper damping parameters and unloading velocity,the working condition of lateral damper has great effect on locomotive riding quality,so it must be ensured that all of dampers are in normal working states when locomotive runs on railway,its running performance is not sensitive to damper position.(5 tabs,) 8 figs,5 refs.更多还原
