| 摘 要： | 利用有限元与边界元耦合法对三维无界区域中直立圆柱所受的波浪力进行计算,把整个求解区域分成内域和外域两部分,在内域采用有限元法,对外域采用边界元法计算,由加权余量法的理论知这种耦合在理论上是可行的,根据此耦合方法编制了完整的计算机程序,对海洋中直立圆柱的波浪力进行了分析.数值计算的结果与理论解吻合良好,表明该方法有效.

| Abstract: | The finite and boundary element coupling method is utilized to calculate the wave force acting on a vertical circular cylinder in the three-dimensional unbounded region. The whole region is divided into two parts, the inner domain and the outer domain. In the inner domain, the finite element method is adopted and in the outer domain the boundary element method is used to calculate the question. The above coupling method is feasible according to weighted residual method. The computer program is developed to calculate the wave force acting on the vertical circular cylinder. The numerical results are in good agreement with the theoretical values, which show the effectiveness of the method. |
