复杂空间桁架结构在不同约束条件下的有限元模拟

Study on Finite Element Simulation for Complex Truss Systems under Different Constraint Conditions

主要介绍了应用MATLAB计算复杂空间桁架结构在不同条件下节点位移、节点外力、单元应变及应力。此外还应用MATLAB建立了GUI界面以获得更好的通用性,并举例进行了说明。

This paper introduces a method that can calculate displacement of node,outside force of node anti internal force of unit by use of the software of MATLAB under different constraint conditions. In order to understand the process of calculations and the principle of FEM,the GUI interface is used. In this paper,an example is inducted for the sake of understanding the program well.
