摘要
利用有限元软件,模拟4种不同载重吨位的船舶以不同的速度与某桥墩发生碰撞的过程,演示有限元法仿真计算船桥碰撞问题的一般过程,着重分析船舶和桥墩的损伤程度。在此基础上,归纳出撞深-速度、撞击时间-速度和桥墩的应力分布。
By means of nonlinear finite element simulation method,the dynamic process of the collisions between ship and bridge pier were calculated for four different ships with tonnages at different initial velocities respectively.A normal collision between ship and bridge pier were simulated.The damage of the ship and bridge pier were investigated in detail.Based on the numerical results,curves of collision penetration-velocity,curves of collision penetration-time and the stress process of the ship and bridge pier were obtained.
