| 摘 要： | 本文利用线性二维截面分析模型，在方程的建立和推导中综合考虑了直升机旋翼桨叶梁的变形特点，和梁截面的面内和面外翘曲对梁截面刚度的影响。在此基础上编制了具有多个不同节点单元可用于计算各向异性材料的旋翼桨叶截面刚度的有限元软件，用复合材料盒形梁作为算例并与ＮＡＢＳＡ的结果比较表明该方法及编制的软件正确可靠。

| Abstract: | An approach is presented for calculation of composite helicopter blade cross-sectional stiffnesses with finite element method on the basis of the two-dimensional linear model.The warping effect and deformation characteristics are incorporated in the formulation.As a result,a software was been developed,which consists of 3 nodes,4 nodes,6 nodes,8 nodes elements.The effectiveness of the program has been verified by means of comparison with NABSA's analytical results. |
