摘要：

A one-way and a two-way solid-fluid interaction models in moving-particle semi-implicit method are established by systematically classifying solid-fluid interaction problems. Numerical simulation of the models are performed on two dimensional dam break problem and wave problem generated by a piston type wave generator. The results agree well with either experimental values or analytical solutions. Free-oscillations of a floating body are simulated, and the maximum error between the height of its mass center and theoretical value is controlled in 0.5% which meets the requirement of engineering calculation. The one-way coupling model and the two-way coupling model are integrately applied in a dynamic response example for sine wave of a board type floating body. Results show that the floating body performs sinusoidal movements in vertical direction and sinusoidal rotation in circumferential direction while moving forward in to-and-fro mode when the length of the body is shorter than the wave length, and that the motion amplitude decreases when the length of the body increases.
