This paper presents a hydrodynamic analysis of a hybrid system consisting of a floating platform coupled with an array of oscillating bodies that move along the front wall of the platform. Using the Lagrange multiplier method, we have formulated the motion equation governing this type of motion characteristics is formulated and derived the formula of the extracted wave power is derived. Our The numerical results demonstrate a significant enhancement in the hydrodynamic efficiency of the oscillating bodies within specific frequency ranges in presence of the floating platform. The incorporation of proper power take-off damping of the oscillating bodies results in a reduction of heave motion of the platform, but it may lead to an increase of pitch motion. By The analysisng of the response behavior of the system shows that both the heave and pitch motion of the platform contribute to the power extraction and relative motion between the buoys and the platform. Additionally, the responses of a multi-module floating platform coupled with an array of oscillating bodies, is investigated which is of considerable engineering interest.
