| 摘 要： | 运用LS-DYNA有限元软件,对5 000 t级的代表船型与某长江大桥1#墩及防撞装置的碰撞过程进行整体仿真,分别对不考虑桥墩自身刚度影响和考虑桥墩自身刚度影响两种工况下不同板厚的桥梁防撞装置的防撞吸能特性进行对比分析。主要从碰撞过程中的撞击力和能量转换的规律等方面考察桥墩自身的刚度对防撞装置在实际碰撞过程中防撞性能的影响,以及在分析此类问题时通常所使用的简化计算模型是否有足够的精确度,从而保证有限元仿真分析数据的可靠性。

| Abstract: | LS-DYNA program was used to simulate the process of a 5000t DWT cargo ship colliding against the bridge-pier protection device of a bridge pier.The laws and characteristics of the collision forces and energy exchange were analyzed.The influence of rigidity of pier on protective capacity of the bridge-pier protection device was studied,and the precision of the simplified calculation model was discussed. |
