In this paper the concept of finite dynamic elements developed by Przemieniecki is applied to the free vibration analysis of bending rectangular plates. As the static shape functions adopted in this paper satisfy governing differential equations and certain boundary conditions are exerted on the second order frequency correction shape functions, the equations of motion established for bending plates consist with those of the conventional analysis when high order frequency terms are neglected.

In this paper the concept of finite dynamic elements developed by Przemieniecki is applied to the free vibration analysis of bending rectangular plates. As the static shape functions adopted in this paper satisfy governing differential equations and certain boundary conditions are exerted on the second order frequency correction shape functions, the equations of motion established for bending plates consist with those of the conventional analysis when high order frequency terms are neglected. It follows that inconsistent shortcomings exhibiting in the finite dynamic element formulations for membranes and plane strain plates may be overcome. Finally, dynamic stiffness and mass matrices developed in this paper are used to calculate the natural frequencies of the cantilever plates. And reasonable results are obtained.

本文把Przemieniecki动态有限元的概念推广应用于弯曲矩形板的固有振动分析。文中构造了满足控制微分方程的静态形状函数阵,并对二阶修正形状函数阵加以某种限制。使得所建立之弯曲板的运动方程,在不计频率高阶项时,能退化到常规分析的形式。从而,克服了Gupta所建立之薄膜及平面应变板动态有限元不能与常规分析相协调的缺点。最后,利用所建立之矩形板元的动态刚度及质量矩阵,计算了悬臂板的固有频率,得到合理的结果,证明了方法的有效性。

In this paper, quasi static shape control equations of adaptive truss structures are presented which are valid in linear elastic range. Generally, the number of active members is much less than that of the truss members. And the placement problem is governed by the control energy and strength requirements. So simulated anealing algorithm is employed to find the multi objective optimal placement of active members with minimum stroke and minimum induced element forces. A numerical example is given to illustrate...
