ZF3700/16/26型液压支架底座的有限元分析及优化研究

Finite element analysis and optimization research of ZF3700/16/26 hydraulic support base

利用SolidWorks和ANSYS Workbench软件建立泰山隆安煤业ZF3700/16/26型液压支架底座的有限元模型,通过分析发现最大应力和最大位移变形分别为515 MPa和4.14 mm,对应的安全系数只有1.07,存在安全隐患。针对这一问题,以过桥宽度、柱窝高度和耳板厚度为优化对象,开展优化改进工作,优化后的最大应力和最大位移变形分别降低29.4%和21.01%,安全系数提升至1.51。将优化后的底座应用到泰山隆安煤业工程实践中,经6个月时间的现场应用,达到了预期效果,使用寿命预计可延长15%左右,可以为企业创造良好的安全效益和经济效益。

The finite element model of ZF3700/16/26 hydraulic support base in Taishan Long'an Coal Industry was established by using SolidWorks and ANSYS Workbench software.Through analysis,it was found that the maximum stress and maximum displacement deformation were 515 MPa and 4.14 mm respectively,and the corresponding safety factor was only 1.07,which had potential safety hazards.In order to solve this problem,the optimization and improvement work is carried out with the bridge width,the height of the column socket and the thickness of the ear plate as the optimization objects.The maximum stress and maximum displacement deformation after optimization are reduced by 29.4%and 21.01%respectively,and the safety factor is increased to 1.51.The optimized base is applied to the engineering practice of Taishan Long'an Coal Industry.After 6 months of field application,the expected effect is achieved.The service life is expected to be extended by about 15%,which can create good safety and economic benefits for the enterprise.
