面内荷载作用下混合型边界约束复合材料层合板的振动特性

摘要

Vibration analysis for laminated rectangular thin plates with twoopposite edges having mixed boundary constraints is presented in this paper.A semi-analytical approach is then developed based on the domain decomposition technique,one-dimensional differential quadrature rule and Galerkin method.Effect of in-plane loading is also taken into account in the formulation.Numerical results shown in tabulated form demonstrate that the vibrational response of the plate is significantly influenced by mixed boundary configuration and fiber orientation.%本文研究—对边界为混合型约束时矩形层合薄板的振动特性问题。文中同时考虑中面荷载作用效应，给出了基于子域分解技术、单向DQ离散格式和Galerkin法的半解析算法，并通过算例讨论了混合边界构成、纤维铺设方式和面内荷载等对板振动特性的影响。
