层合板弯扭耦合的动态和静态分析

AN ANALYSIS OF DYNAMICS AND STATICS OF BEND-TORSION COUPLING OF LAMINA

从动态和静态角度提出估计层合板弯扭耦合的计算方法,根据计算结果,探讨了影响层合板弯扭耦合的因素。弯扭耦合程度与层合板的材质、层数和约束条件有关,说明了弯扭耦合的层合板的挠度、固有频率和振形的特征,并提出减少弯扭耦合效应的措施。

A calculative method for evaluating bend-torsion coupling of lamina was presented. As viewed from statios and dynamics,and on the basis of calculated results, the factors of effect on bend-torsion coupling of lamina were investigated. The degree of bend-torsion coupling of lamina is related to its material,,number of layer and restricted condition. For the lamina having bend-torsion coupling, the characters of its deflexions,natural frequencies and modes were analysed. And a method for reducing effect of ben-torsion coupling of lamina was given.
