The Finite Element Analysis of the Plane Truss Based on the MATLAB

基于平面桁架有限元分析的基本原理,利用MATLAB软件对某平面桁架编制了计算程序,得到了结构的内力计算结果、变形图和结构的动力特性,并将计算结果与ANSYS有限元分析软件的结果进行比较.结果表明,二者的计算结果一致.利用MATLAB可以编制结构有限元分析程序,计算速度快,数据准确,并能为复杂结构有限元分析提供参考.

Based on the finite element analysis basic principles of the plane truss,the plane truss calculation program was worked out by using MATLAB.The internal force calculation results,deformation figure of the structure and the dynamic characteristics of the structure were obtained.And the calculation results are compared to the results by using ANSYS finite element analysis software.The results show that,the calculation results are consistent.The structure finite element analysis program is feasible by using MATLAB,as the calculation speed is faster,the data is accurate,and the method provides the reference for complex structure finite element analysis.
