基于MATLAB的ANSYS结构刚度与质量矩阵快速提取程序：实现刚度矩阵提取、质量矩阵提取及自振频率计算,基于Matlab的Ansys有限元模型刚度矩阵与质量矩阵快速提取工具,基于matlab的ansys结构刚度矩阵、质量矩阵提取【程序简介】现成Ansys命令流+matlab程序，替建模部分命令流，直接运行matlab程序即可，具体如下：[1]利用Ansys建立有限元模型；[2]利用HBMAT命令提取结构原始刚度、质量矩阵，也可以提取结构总体刚度、质量矩阵；[3]利用matlab读取Harwell-Boeing文件格式组装结构刚度矩阵和质量矩阵，并利用质量、刚度矩阵计算结构自振频率，结果与Ansys对比一致。[闪亮]程序已通过多个模型得到验证，无其他繁琐操作，直接运行程序即可获得结构刚度与质量矩阵，为二次开发提供。,基于matlab的ansys结构刚度矩阵;质量矩阵提取;HBMAT命令;Harwell-Boeing文件格式;自振频率计算,基于Matlab的ANSYS结构刚度与质量矩阵提取程序
