摘要
简述船 桥碰撞有限元动态模拟计算原理和实际应用的关键问题,通过5万吨船首碰撞桥墩的计算示例,说明结构模型化的过程、碰撞中力和能量的时间历程和结构的损伤情况,分析防撞装置的作用。
The calculating theory and the pivotal problem of practical application about the nonlinear FE dynamic simulation of shipbridge collision is discussed briefly. According to the calculating demonstration of the collision between 50,000 DWT bulk ship bow and the pier, the modeling process of the structure, the time course of the collision force and the losing energy is explained, and the function of the fending device of the pier is analysed.
