为深入了解机车车辆二系横向止挡结构对机车动力学性能的影响并为转向架设计提供理论指导,以机车通过曲线轨道工况为例,研究了止挡结构参数(包括止挡间隙和止挡刚度)对行车舒适性和安全性指标的影响规律.研究结果表明:止挡间隙和止挡刚度对车体的横向振动加速度影响较大,而对轮轨动态相互作用性能指标的影响甚微,适当增大止挡间隙或减小止挡刚度,可以减小车体的横向振动.
In order to deeply understand the influence of locomotive vehicle secondary lateral stop structure on the locomotive dynamic performance and provide theoretical guidance for the bogie design, taking the locomotive as an example, the structure parameters of stop (including stop gap and stop Gear stiffness) on the driving comfort and safety index.The results show that: the stop gap and the stop stiffness have a great influence on the lateral vibration acceleration of the vehicle body, but have little effect on the wheel-rail dynamic interaction performance index , Appropriate to increase the stop gap or reduce the stop stiffness, can reduce the body’s lateral vibration.
