摘      要：This study develops a method for the full-size structural design of blade,involving the optimal layer thickness configuration of the blade to maximize its bending stiffness using a genetic *** differentiation is employed to solve the sensitivity of blade modal frequency to the layer thickness of each part of *** natural frequencies of first-order flapwise and edgewise modes are selected as the optimal *** on the modal sensitivity analysis of all design variables,the effect of discretized layer thickness on bending stiffness of the blade is explored,and 14 significant design variables are filtered to drive the structural *** best solution predicts an increase in natural frequencies of first-order flapwise and edgewise blade modes by up to 12%and 10.4%,*** results show that the structural optimization method based on modal sensitivity is more effective to improve the structural performance.
