摘要
对具有任意分层、任意纤维铺设角的层合矩形板的自由振动进行了研究，提出了一种确定各向异性层合矩形板各阶固有频率及相应振型的三维弹性分析方法．板由多层纤维增强材料制成，每层纤维对板边可接任意方位角铺设．层数、层厚及板的尺寸均为任意，沿板田边的支承条件可为固定、简支和自由的任意组合．文中提供了若干数值算例。
In this paper,free vibrations of laminated rectangular plate which has arbitrary plies and liad-angles formed by fibres are analyzed.A three-dimensional elastic analysis method is introduced for determining the natural frequencies of orders and the correspondent oscillation modes of laminated anisotropic rectangular plate.The plate is made of multi-ply reinforced fibre materials,the fibres of each ply are laid at arbitrary angles with the edges of the plate,the number and thickness of plies as well as the dimensions of the plate can be arbitrary.The boundary conditions of plate edges can be arbitrary combinations of clamped,simple-supported,and free.Some numerical results are presented.
