The paper proposed a calculation method for a two-body articulated wave energy device with a complex geometric shape. The hydrodynamic performance of the Eagle wave energy device as an example was studied. The hydrodynamic calculation was carried out by the boundary element method based on the simple Green's function to solve the wave excitation force and hydrodynamic coefficients. Based on the above, the motion equation was obtained. Using the motion equation, the hydrodynamic response and capture width ratio of the device at different wave frequencies were calculated. In summary, this computational result can be used to evaluate and optimize the performance of the articulated wave energy device.
