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。

At present the 4200 heavy plate mill is regarded as the largest model of its type in China.Making use of the pro- gram(VSFM)compiled by the author himself,he calcu- lated the natural frequency and the principal vibrational pat- tern of the main driving system on the 4200 mill.Matrices are derived for the vibrational patterns of the elastic mo- ment of force in individual segments on the shaft undergo- ing free vibration,and the distribution of the moment of force in the system.Thereby a conclusion as regards the rationality of the driving power design of the main driving system is derived.

4200轧机是我国目前最大的厚板轧机。本文应用作者编制的计算机程序(VSFM程序)计算了该轧机主传动系统的固有频率和主振型。通过对计算结果的分析,推导出该系统自由振动的各轴段弹性力矩的振型矩阵和力矩的分布情况,并得出了关于该轧机主传动系统结构动力设计的合理性的结论。

The solution of bending free vibration of step beam has been derivated in this paper. It can be considered as an approximate solution of an arbitrary section beam.

变截面梁的弯曲自由振动,一般是难以求得精确解的,仅有个别形状的变截面梁有精确解。本文给出了阶形梁弯曲自由振动解。该解对于阶形梁是精确的,并可用来较好地近似任意变截面梁。为了得到足够的精度,只需适当地采用一定数目的阶形,即可获得足够精确的近似解。笔者认为,本文推导出来的解答是用来解决各种变截面梁弯曲自由振动的有效方法之一。
