摘要
利用SolidWorks和ANSYS软件构建了 ZY13000型液压支架的有限元模型,对掩护梁结构承受冲击载荷时的受力情况进行仿真分析.结果发现,掩护梁结构承受的应力非常不均匀,最大应力达到了 674.3 MPa,几乎接近材料的屈服强度690 MPa,存在一定风险.从掩护梁整体箱型结构和千斤顶耳座结构两个方面进行优化设计,再次对优化后的掩护梁结构进行受力分析,发现最大应力降低至446.1 MPa,降低的幅度为33.84％.将优化后的掩护梁结构应用到液压支架工程实践中,经过6个月时间的现场测试,发现整体运行良好,使用寿命可延长20％左右.
Abstract
The finite element model of ZY13000 hydraulic support was constructed by using SolidWorks and ANSYS software to simulate and analyse the stress on the cover beam structure when it is subjected to impact load.It was found that the cover beam structure was subjected to very uneven stress,and the maximum stress reached 674.3 MPa,which was almost close to the yield strength of the material of 690 MPa,and there was a certain risk.Optimisation of the cover beam structure was carried out in terms of the overall box structure of the cover beam and the structure of the jacking lugs,and the optimised cover beam structure was analysed again,and it was found that the maximum stress was reduced to 446.1 MPa,with a reduction of 33.84％.The optimised cover beam structure is applied to the hydraulic support engineering practice,and after 6 months'field test,it is found that the overall operation is good,and the service life can be extended by about 20％.
