基本解释

Meanwhile, comments and discussions on the high accuracy finite dynamic element method that increases element nodes were presented.
同时，高精度动态有限元法增加元素节点上的评论和讨论。
In this paper, the basic relations of the natural vibration characteristics of framed structures have been studied by means of the dynamic finite element method.
本文用动力有限单元法对框架式结构自振特性基本规律进行了一定的研究。
In the finite dynamic element method, the dynamic characteristics. of struture is included the function matrix in order to improving the accuracy of the dynamic analysis of structures.
动态有限元法将结构的动态特性引入单元性态中，以结构的动特性为基础来构造位移形函我，从根本上改变单元性质，使之成为结构动态分析的高精度单元。

动态有限元
Finite dynamic element method (DEM) established on the theoretical basis of finite element corrects the shape functions of FEM. Shape functions with frequency are adopted which replace the static ones to resolve dynamic property problems of structures.
建立在常规有限元方法理论基础之上的动态有限元方法,通过对常规有限元模型中的形状函数矩阵加以修正,采用含有频率变量的形状函数来代替静态形状函数求解结构的动力特性。
