Dynamic Analysis And Emulation Of Float-Type Wave Power Generation Boat

It is an important way to acquire energy for wave power is used togenerate. Efficiency of wave power generation device is vital to realizing wavepower generation substitute some conventional energy. Therefore, structuraldesign and parametric analysis of wave power generation device plays animportant role in generating efficiency and realizing industrialization.Firstly, the status of domestic and foreign's research on wave powergenerating technology and existential problem are analysed, operating principleand merits and faults of all kinds of wave power generation devices is studied.Combining floating wave power theory, the new generating device that isfloating-type wave power boat is presented.Secondly, based on micro-wave amplitude theory and potential function oftranslatory wave. Then, chief characteristic parameters of wave motion aresolved, such as velocity,accelerated velocity and moving trace of waterparticle,pressure and wave energy of wave power. Froude-Krylov AssumptionMethodstress analysis is used to analysis the stress of several common float,thedynamic state mathematic model of the float is established. The shape of floatis elected optimizly. Basic geometric parameter of float is defined. Combiningbasic knowledge of wave theory and wave energy transition,relation ofgeometric shape of float and virtual mass,water intercepting area,wave forceamplitude is discussed,total energy capacity of fluctuation system and wave isresolved,the dynamic state mathematic model of energy absorbing rate isestablished,and energy absorbing rate of float is resolved.Structural design is done to float arm. By stress analyzing, the best lengthof float arm is determined, and its strength is checked.moment of float armcarryout terminal is deduced,on that base, the dynamic state mathematic modelof electric generator power is established, structural analysis and design ismade to generate electricity boat, the dynamic state mathematic model of shiphull draught is established.Finally, simulation experiment is made to power-absorbing of float wavepower generation device by advanced dynamics analyses software ADAMS.Certifying accuracy of theory and model building, which is a basis for physicsmodel machine.
