摘要
本文应用能量法与谐波平衡原理求解加筋夹层板的几何非线性自由振动问题。对位移选用多模态近似解析解将连续体进行离散求解.计算了不同边界条件的算例,讨论了加筋(布局、数量、尺寸)对夹层板结果的影响。数值计算表明本文解法非常有效。
In this paper, the geometric nonlinear free vibration problemof the laminated plate with ribs is solved by the energy method and theharmonic balance principle. The discretization is carried by using theapproximate analytical solution with multiplemode to express the displacem-ents. Solutions for different boundary, size and disposition of the laminateson the response of the plate is investigated. The efficiency of the method isverified by the mumerical examples.
