Abstract

Based on the calculation method of multi-body floating motion response, the OrcaFlex software is used to conduct numerical analysis on the stiffness and motion response of multi-body floating connectors aiming at the floating square array model of photovoltaic power station. The rationality of numerical simulation is verified by comparing with the floating body connection test. Then, the 6-DOF motions of multiple floating bodies with different stiffness connectors and numerically calculated, and the 6-DOF motions of horizontal and vertical floating bodies are evaluated. Finally, the influence between the relative motion of floating body and the load of connecting piece is analyzed. The results show that the overall motion response of the transverse floating body is greater than that of the longitudinal floating body with the increase of the stiffness of the connector, and more attention should be paid to the connection strengthening of the transverse floating body. When the stiffness of the connecting piece is small, the motion constraint ability between floating bodies is poor. When the stiffness is large, it is not conducive to resist the impact between floating bodies, resulting in unnecessary actual engineering costs.
