为提高固体充填液压支架底座的强度和可靠性,以ZZC8800/20/38型六柱支撑式固体充填液压支架底座为研究对象,根据其结构和工作特点,建立了顶梁和底座的受力模型,并对底座进行工况分析,确定了其危险工况和对应的加载方式,利用Pro/E软件建立了底座的有限元模型,采用有限元法,在ANSYS Workbench软件中对其进行了有限元强度分析,根据分析结果对底座进行结构优化改进,通过优化前后有限元结果对比,结果表明,优化后底座的强度得到了明显的提高,特别提高了底座的抗弯抗扭能力,最大等效应力下降了79.1%,最大变形位移减小了35%。
In order to improve the strength and reliability of hydraulic support base, the hydraulic support base of ZZC8800 / 20/38 six-post support type solid support was set up as the research object. According to its structure and working characteristics, , And the working conditions of the base were analyzed to determine the dangerous conditions and the corresponding loading method. The finite element model of the base was established by using Pro / E software. The finite element method was used to carry out finite element analysis in ANSYS Workbench software. Strength analysis. Based on the analysis results, the base structure is optimized and optimized. The comparison between the finite element results before and after optimization shows that the strength of the base has been obviously improved after the optimization, especially the flexural and torsional resistance of the base, the maximum equivalent stress Decreased by 79.1% and the maximum deformation displacement decreased by 35%.
