Disclosed is a method for analyzing hydroelastic effect of a marine structure based on moving particle semi-implicit method and modal superposition method. The method is based on a fluid dynamic solver of a moving particle semi-implicit method (MPS) and a structural response solver of a mode superposition method, and the fluid dynamic solver and the structural response solver achieve strong coupling in a time domain in an iterative mode. According to the present disclosure, the deficiency of the traditional potential flow-based hydroelesticity calculation (i.e. cannot directly simulate the severe deformation of the free surface and the slamming phenomenon of the ship body) is improved, and the problem of mutual influence between the rigidity of the structure and the flexible motion modal is considered.
