| Abstract: | The crane for offshore wind farms is designed with max lifting capacity of 460t and max lifting height of 100m.Flexible finite element models of sheer-leg,jib and turntable structure are proposed,which is comprehensively used by structural element,solid element,connector and constrain equation.And mechanical properties of the crane are analyzed by FEA under critical working conditions.Designing flaw is found and modified.Finally,strength,stiffness and buckling of the modified crane are analyzed. |
