Research Of Flexible Fixing System Of Buoy-type Wave Energy Generation Device

Ocean wave is kind of clean and regenerate energy source and China is rich insuch energy. Further research on energy transferring equipment has an importantmean to solve the decreasing energy and environment problem. The viability ofoscillating buoy wave power device is difficult. So the research about how to fixsuch equipment at sea is very important to the practical application of ocean wavegenerator.A modified calculation method of Froude-Kryloff hypothesis is proposed tocalculate the wave force of small and regular floating body. For small and irregularfloating body, a simulation calculation method of Fluent is proposed. The waveforce in small and regular floating body is calculated by both modified calculationmethod of Froude-Kryloff hypothesis and simulation calculation method of Fluent.The calculations are compared and the reason of deviation is analysed. Theimproved schemes of the two wave force calculation methods are put forward tomake the calculation methods more close to the reality.The current buoy wave power generator equipment is analysisd, aflexible-fixing equipment is mentioned and the theory of it is explorated. Suchequipment fixes the generator at sea by using mechanical system and makes itadapted to the wave and tide environment. The research includes the calculation ofwave force, the whole mechanical design, ADAMS verification for locking system,real-time validation for cable winding device.According to the simulation method, the fixing system of buoy-wavegenerator equipment is designed in the paper. The working theories of locking andpressure sensor in flexible-fixing system are designed and selections of thestructure of them are made. locking and pressure sensor, So it is come true thatbuoy-wave generator equipment generates the electrical power under minor wavesituation, but when under strong wave situation, the fix could move up and downwith sea level to achieve flexible-fixing.Design the theory of simulation structure to experiment the practical use ofpressure sensor and locking equipment, use the software ADAMS to build thesimulation mould and carry out the simulation trial to the design of pressure andlocking equipment. The result shows that the design of the system could achievethe function of sensing the sea level to switch the lock. The possibility of error ofthe simulation analysisd and the further improvement is mentioned. To build thesimplified structure model of cable winding device in ADAMS software andanalysis real-time validation for cable winding device by kinematics analysis. The proper improvement is proposed according to the model’s structure and parametersto reduce the delay and the final flexible-fixing system structure is gotten.This thesis researchs about the calculation method of wave force duringvarious sea situation which is a theory-proof of wave force calculation, mentionsthe flexible-fixing system of buoy-wave generator equipment. simulation andimprovement are carried out through ADAMS. And the paper will provide afeasible method to solve the problem of the survival of minor wave generatorequipment at sea.
