At present,the world's energy structure is still dominated by fossil energy,but the exhaustion of fossil energy and the environmental pollution caused by it still bother people.Therefore,it is imperative to develop new energy and take the road of sustainable development.Wave energy,as the largest and high-quality energy of ocean energy,has the characteristics of high energy density and wide distribution.The development and utilization of wave energy has become an indispensable part of the development of new energy.Based on the oscillating flapping-wing wave energy power generation device,the device relies on the power generation platform lifting system to match the best collection conditions under different sea conditions and wave heights,as well as self-protection in severe sea conditions.Therefore,the safety and reliability of the power generation platform lifting system is An important guarantee for the efficient operation of wave energy power generation devices is of great significance to the research of lifting systems.In order to solve the lifting problem of the oscillating flapping-wing wave energy power generation platform,this paper proposes a rack and pinion meshing lifting system design scheme,and analyzes and studies its transmission system and control strategy according to actual operating conditions.According to platform design criteria,operating conditions and stability requirements,the motor model,transmission system,reduction mechanism and locking device are selected and designed.Using the ADAMS virtual prototype technology,the kinematics simulation of the platform lifting system is carried out,and the kinematics characteristics of the system under different loads and the dynamic characteristics of the rack and pinion are analyzed.Lay a theoretical foundation for the construction and optimization of the physical prototype of the subsequent lifting transmission system.Combined with the theory of synchronous lifting,the method of synchronous lifting control of offshore platform is analyzed,and a speed-displacement deviation coupling synchronous lifting control strategy is proposed.A four-motor control model was built in the MATLAB/Simulink environment,and the platform motion control strategy was simulated and analyzed.The experimental results show that the speed-displacement deviation coupled synchronous lifting control strategy can effectively realize the smooth synchronous lifting function of the power generation platform,which verifies the design The feasibility of the control strategy.
