摘要
传统的水下结构物设计较为注重正常操作下的结构杆件分析,而对于突发工况则需要更为先进的方法处理。基于耦合的欧拉-拉格朗日(Coupled Eulerian-lagrangian,CEL)方法的有限元能高效处理瞬态和大变形问题,为此采用该方法对于落入水中的储液罐与水下结构物的碰撞进行碰撞模拟,并对结果进行分析讨论。
The traditional design of subsea structures pays more attention to the analysis of structural elements under normal operation,while more advanced methods are needed to deal with sudden conditions.The finite element method based on the Coupled Eulerian-lagrangian(CEL)method can efficiently deal with the transient and large deformation problems.Therefore,this method is used to simulate the collision between the liquid storage tank falling into water and the underwater structure,and the results are analyzed and discussed.
