摘　　要：液压支架作为煤矿重要的支护设备之一,在采煤安全稳定生产作业过程中发挥着重要的作用。文章以ZY4000型矿用液压支架为研究对象,针对其顶梁结构易出现故障损坏等问题,采用UG软件建立支架的三维立体模型,并通过Ansys软件分析顶梁结构在偏载及扭转工况下的强度及变形特征。分析结果表明,顶梁在扭转工况下的最大应力值超过材料的屈服极限。因此,需通过加厚筋板等应力集中部位的厚度来对结构进行优化,优化后支架顶梁的最大应力降低了65.23%,最大变形量降低了12.29%,顶梁的应力最大值降低到了材料的屈服强度以下,结构优化设计为矿井的安全生产奠定了良好的基础。Hydraulic support is one of the important support equipment in coal mines,which plays an important role in the safe and stable production process of coal mining.In this article,taking the ZY4000 mining hydraulic support as the research object,in response to the problems of easy failure and damage to its top beam structure,a three-dimensional model of the support is established by using UG software.The strength and deformation characteristics of the top beam structure under eccentric and torsional conditions are analyzed by using Ansys software.The results show that the maximum stress value of the top beam under torsional conditions exceeds the yield limit of the material.By increasing the thickness of stress concentration areas such as the reinforced plates,the maximum stress of the support top beam is reduced by 65.23%,the maximum deformation is reduced by 12.29%,and the maximum stress of the top beam is reduced to below the yield strength of the material,laying a good foundation for the safe production of the mine.
