机械式半主动控制橡胶节点的计算机仿真

橡胶节点的研究是为了有效解决车辆稳定性与曲线通过性能之间的矛盾,而可控的轴箱纵向定位刚度是解决这个问题的关键.为了解决这一问题,根据自导向径向转向架的设计要求,提出一种新型机械式半主动控制橡胶节点,它能够在保证车辆在具有较高稳定性的前提下,提升车辆的曲线通过能力,降低轮轨磨耗.对新型机械式半主动控制橡胶节点的基本结构及其工作原理进行了详细的介绍,并用SIMPACK对其在不同工况下的动力学性能进行仿真分析,证实了该设计方案为解决车辆稳定性和曲线通过性能之间的矛盾提供了新的方法,而其应用的可行性和可靠性还有待在实践中做进一步的论证.

Simulation of Rubber Nodal Points with Mechanical Semi-active Control

Research of rubber nodal points is to overcome the contradiction between vehicle stability and curve passing,and the controllability of longitudinal restraint for axle box guidance is the key technical problem.Now an innovative semi-active control mechanism of rubber nodal points is put forward for axle box guidance,which could compromise the contradiction for railway vehicles.The mechanism is studied by means of SIMPACK to simulate and analyze its dynamic indices in different computing work conditions,which can reflect vehicles stability and curving performance.The final simulation shows the new mechanism may solve the problem of contradiction between vehicle stability and curve passing,but its feasibility and reliability need to be verified further in actual projects.
