Moving particle semi-implicit (MPS) method was developed for analyzing incomplessible flow with particle models. In the present study, a numerical model for thin walls is developed and the MPS method is extended to analyze fluid-structure interactions with large deformation of free surfaces and walls. First, sloshing in a rigid rectangular tank is calculated. A finite amplitude wave occurs in a shallow tank, while a standing wave appears in a deep tank. Results are in good agreement with the experiments by Hayama et al., though the calculated sloshing amplitude is smaller than the experimental one in the deep tank. This is attributed to unknown dissipation mechnisms in the present method. Next, sloshing in a tank with elastic walls is calculated. The calculated resonance peak is shifted to a lower frequency due to large deformation of the walls.
