架桥机运输平车曲线通过性能分析

Analysis of the Negotiation Performance of Flat Cars for Transport of Bridging Machines

运用SIMPACK软件,建立了架桥机运输平车的多体拓扑关系图,并对其进行了几何曲线通过和动态曲线通过分析。仿真结果表明,架桥机运输平车的曲线通过性能主要由五轴转向架决定,当车辆处于缓和曲线时,五轴转向架的1位轮对安全性最差。

The SIMPACK software is used to establish the multi-body topography of the flat car for transport of bridging machines. The geometrical negotiation and dynamic negotiation analyses are made. The simulation result shows that the negotiation performance of the flat car for transport of bridging machines is mainly determined by the 5-axle bogies, and when the vehicle is on transition curve, the safety of the No.1 position wheel-set of the 5-axle bogie is the poorest.
