为了减小提速机车在提速区段异常振动,提高机车运行平稳性,以抗蛇行减振器为研究对象,运用机车车辆-轨道耦合动力学理论,以机车运行平稳性指标为依据,从机车抗蛇行减振器的工作状态、卸荷速度、结构阻尼参数等入手,研究了抗蛇行减振器与机车运行平稳性的关系。仿真计算与分析结果表明:抗蛇行减振器的工作状态对机车运行平稳性有较大的影响,必须严格确保所有减振器的工作状态均正常;取适当的卸荷速度可以达到提高乘车舒适性的目的;抗蛇行减振器的结构阻尼参数越大,对提高机车的平稳性越有利。
In order to reduce the abnormal vibration of speeding locomotive in the speed raising section and improve the locomotive running stability, take the anti-snake shock absorber as the research object, based on the locomotive vehicle-track coupling dynamics theory and locomotive running stability index, The work status, the unloading speed and the structural damping parameters of the meander shock absorber are studied. The relationship between anti-meandering shock absorber and locomotive running stability is studied. The results of simulation and analysis show that the working condition of the anti-snake shock absorber has a great influence on the running stability of the locomotive, and the operating conditions of all the shock absorbers must be strictly ensured. Appropriate unloading speed can improve the riding comfort The purpose of comfort; anti-snake shock absorber structure of the damping parameter is greater, to improve the stability of the locomotive the more favorable.
