Abstract: An improved Wilson-θmethod is obtained on the basis of the traditional Wilson-θmethod and its stability is analyzed. From the improved Wilson-θmethod, an iterative algorithm for solving the dynamic coupling equation is derived. The algorithm can be used to solve the dynamic reaction of fluid-structure coupling systems with ease. A computation example shows that the iterative algorithm is feasible and can enhance calculation efficiency
