摘要
在平面刚架有限元计算的基础上,利用二维图形的矩阵变换原理,将单元内力和位移绘图数据进行伸缩、旋转和平移变换,在Matlab中实现了平面刚架内力图和位移图的绘制。本文提出的绘图方法,可用于杆系结构有限元计算结果的图形显示。
On the basis of the results of FEM analysis and the principle of matrix transformation of two-dimensional diagrams,scaling,rotation and translation are carried out for the element drawing data about internal forces and displacements of plane frame,and the diagrams of them have been drawn by Matlab.The method suggested in this paper can be applied to display of data results from the FEM analysis of plane frame in graphics mode.
