摘　　要：该文基于Python和Qt框架研发一款具有前后处理模块的二维边界元法CAE软件,为用户打造一个直观的可视化操作界面,通过该界面可实现几何模型构建、单元结点信息获取、边界条件加载和材料属性施加等前处理功能,以及显示位移、应力云图的后处理功能,可直观展现边界元法计算结构获得的物理参量。最后以含切口薄板结构受力分析为例,利用所开发的软件进行计算,展现所开发软件的功效。In this paper,a two-dimensional boundary element method CAE software with pre-and post-processing modules is developed based on Python and Qt framework,which creates an intuitive visual operation interface for users.Through this interface,pre-processing functions such as geometric model construction,element node information acquisition,and boundary conditions can be realized.Pre-processing functions such as loading and material property application,as well as post-processing functions to display displacement and stress nephograms,can intuitively display the physical parameters obtained by the boundary element method calculation structure.Finally,this paper takes the stress analysis of thin plate structures with notches as an example,and uses the developed software to calculate,which demonstrates the effectiveness of the developed software.
