The Design And Research Of A New Installation Equipment For Offshore Wind Turbine

Nowadays offshore wind power is developing fast, the installation ofoffshore wind turbine is increasing. But the installation is difficult toaccomplish and requires tremendous resources for the hugeness, heaviness ofwind turbine and the severe environment of offshore. The present installationequipment has several parts. The installation efficiency is low for itscomplicated structure and difficulty to control. And this is a fataldisadvantage in a mutable environment such as offshore. Considering all ofthese, it is necessary for an efficient installation equipment, which is easy tocontrol, to be developed.In the simulation of wave using P-M spectrum, we find that the troughsand crests change abruptly. We take the time history of wave formation intoconsideration by using the theory of random vibration correlation function,and set forth an improvement to the classical mathematic model of wavesimulation. The correctness of the improvement is proved by the comparisonof the numerical simulations. Then we design the mechanism configurationof the offshore wind turbine based on the theory of generalized function (G f)set and the dimensions of the installation equipment is obtained through GAoptimization. Further more, the inverse and forward kinematics analysis,workspace analysis and fussy reliability analysis of the installation equipment is accomplished. Finally, modal analysis of the equipment is conducted basedon the theory of finite element.
