摘要
采用非线性有限元技术,探讨了下落物体撞击海洋平台的数值仿真模型。研究了不同撞击速度与位置对撞击力、撞击损伤变形及能量吸收的影响。数值模拟采用非线性动态分析软件MSC/Dytran完成。
By adopting nonlinear finite element technique, the paper discusses the model simulating, the parameteres of fallen objects colliding on offshore platform,and studies the effects of the collision forces with different velocities and places, the structural damage and the energy absorption capacity. The simulation is carried out by MSC/Dytran, a three-dimensional analysis code for analyzing the dynamic, nonlinear behavior of the structure.
