In order to develop and utilize the wave energy of ocean, the paper designed a floating wave energy device which is capable of collecting new wave power generation system and described the working principle of the device.It used UG software simulation to anzlyze the kinematics for the device,and calculated the transmission performance of device under different speed input functions and adverse sea conditions, verified the effect of transfer process.The results show that the work state of experimental apparatus additional common types of speed function is normal.The device has high practical performance and better adaptability to sea conditions. Simulation results with theoretical calculation are in good agreement.The result has guiding significance for theoretical research of floating wave power device.
