摘要
近年来磁悬浮列车因其运行速度快、乘坐舒适等优点被很多大中城市青睐,但由于其空间密闭,一旦发生事故,后果严重.为了提高车体被动安全性,最大程度上降低事故损失,以中低速磁悬浮头车为载体,应用碰撞仿真软件PAMCRASH对中低速磁悬浮头车车体进行大变形碰撞仿真,通过对车体端部二级吸能结构压溃管的壁厚、结构形状、材料、诱导方式及焊接方式对其吸能特性的影响进行研究,并选择合理参数确定了压溃管的最终实际优化方案,为吸能部件的研发和再生产提供必要的理论依据。
In recent years,because maglev train is fast and comfortable ride,so it is favored by many cities,but because of its confined space event of an accident,the consequences are serious. In order to improve vehicle passive safety and reduce accident losses to the maximum extent it takes low-speed maglev train for the carrier,applying crash simulation software PAM-CRASH simulates large deformation collision of subways. Additionally,by studying the affection of secondary energy absorption characteristics for several major factors such as wall thickness,structure shape,material properties,inductions and welding,deduced the final actual crush tube＇s optimization. It provides the necessary theoretical basis for energy-absorbing parts of development and reproduction.
