摘要: 1、各向异性弹性柱体扭转的理论 复合材料旋翼桨叶的扭转问题简化为各向异性的弹性柱体的扭转问题,忽略桨叶的根部影响,是一个弹性柱体的自由扭转问题。 假设各向异性的弹性柱体,其正截面的形状不受限制(图1)可以是单连通的亦可以是复连通的(图2)。柱体内部不受外力(包括重力)作用。柱体周围侧面也是悬空的,即

Abstract: This paper improves the finite cloment solution for Saint-venant torsion presentedby J.L.Krahula and G.F.Lanterhach and presents the numerical results of rotor blade cross sections of two helicopters,Finally, the calculated results are compared with experimental data and good agreement has been observed.
