摘要
基于平面桁架有限元分析的基本原理,利用MATLAB编写了结构自振频率及模态图的求解程序,得到了结构的固有频率与模态图,并将计算结果与MIDAS有限元分析软件的结果进行比较.结果表明:利用MATLAB编写的结构有限元分析程序效率高、数据准确,且MATLAB结果更加可视化,可为复杂桁架结构的有限元分析提供参考.
Based on the finite element analysis,using MATLAB,the program for computing the natural structural natural frequency and modal figure is compiled. The natural frequency and model figure of the structure were obtained. The calculation results are compared to the results by using MIDAS finite element analysis software. The results show that the structure finite element analysis program is feasible,the efficiency is high,the data is accurate and more visual. The method provides the reference for complex truss structure finite element analysis.
