英文摘要：

The motion response of two floating bodies in irregular waves is calculated by means of three-dimensional （3- D） potential flow theory, in consideration of their coupling influence. Then the relative motion of two connections on the modules is computed to find the optimal status for connecting, which provides exact basis for floating bodies connecting. On the basis of the computation of the relative motion of two floating bodies in irregular waves, a suit of realistic representations software, which is of fully interactive and realistic effect, was programmed with Visual Fortran programming language and OpenGL （ open graphics library ） to simulate the relative motion of two floating bodies. The transfinite interpolation scheme is employed for the mesh generating of the free surface, and surface elevation is calculated by 3-D potential flow theory to simulate the wave motion.
