摘要
基于ANSYS平台对液压支架顶梁进行参数化建模,针对顶梁扭转工况进行了有限元数值模拟,进一步利用ANSYS的优化功能,对顶梁截面参数进行优化,完成了顶梁的减重设计,优化方案较原设计方案最大等效应力降低6.5%,重量减少11%,减重效果十分显著,为液压支架和类似结构优化设计提供了有益参考。
The paper aims to build the FEM model for roof timber supported by hydraulic power parametrically, based on ANSYS, to perform numerical simulation under the condition of the roof timber in tortion, furthermore to optimize the transect parameters and achieve the weight reduction design of roof timber by using the optimization function of ANSYS. Compared to the original set, the optimized one dramatically reduces 6.5% in Von Mises stress and 11% in weight, which offers a useful reference to design optimization of the hydraulic powered support and similar structural optimization.
