The kinematic model and energy model of wave energy device are established by taking the case of a box floating structure as an example. The numerical analysis method was used to calculate and analyze the absorption power density, the kinetic response and the energy output parameters of the devices under different wave environments and different structural parameters. The numerical results show that the wave energy device based on roll motion is more suitable to work in medium and high frequency wave environment. The maximum absorption of wave energy can be achieved by reasonably designing the stability of floating body and optimizing the energy output.
