摘要
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。
The roof beam of filling mining hydraulic support is designed in traditional design principles. The geometry is built by ProlE 3D drawing software and supported into Ansys software via the intermediate file IGS, then the stress distribution and displacement variation of roof beam structure is obtained based on the finite element analysis of hydraulic support under partial loading conditions. And then, taking cross sectional area as the objective function, the roof beam thickness and steel plates as design variable, bending strength, shear strength and roof beam thickness as constraint conditions, the best optimizing results of hydraulic support beam box structure are obtained through MATLAB software.
