参照传统支架的设计原则设计充填采煤液压支架的顶梁,采用Pro/E三维制图软件建立顶梁的模型,然后通过IGS中间文件将支架的三维实体模型导入ANSYS软件,对偏载工况下的充填采煤液压支架的顶梁梁体进行了有限元分析,得到了顶梁梁体结构的应力分布和位移变化规律。并在此基础上以液压支架顶梁截面的面积作为最小目标函数,顶梁厚度和肋板厚度作为设计变量,并以弯曲强度、剪切强度及顶梁厚度作为约束条件,应用MATLAB软件对液压支架顶梁箱式结构进行优化设计,得到了较理想的优化结果。
According to the design principle of traditional supports, the roof beam filled with coal mining hydraulic support was designed. The roof beam model was established by using Pro / E 3D mapping software. Then the three-dimensional solid model of support was imported into ANSYS software through IGS intermediate file. The finite element analysis of the roof beam of the hydraulic support filled with coal mining has been carried out and the stress distribution and displacement variation of the roof beam structure have been obtained. Based on this, taking the area of the cross-section of the top beam of the hydraulic support as the minimum objective function, the thickness of the top beam and the thickness of the rib as the design variables, the bending strength, shear strength and the thickness of the top beam are taken as constraint conditions. The optimal design of the box girder structure of the support was achieved, and the optimal result was obtained.
