Finite Element Analysis and Structural Optimization of Roof Beam of ZY4000 Type Mining Hydraulic Support
Taking ZY4000 mining hydraulic support as the research object,in view of its roof beam structure is prone to failure damage and other problems,the three-dimensional three-dimensional model of the support was established by using UG software,and the strength and deformation characteristics of the roof beam structure under partial load and torsion were analyzed by using Ansys software,and the results showed that the maximum stress value of the roof beam in the torsion exceeded the yield limit of the material.By thickening the thickness of the stress-concentrated parts such as the fascia plate,the maximum stress of the top beam of the support is reduced by 65.23％,the maximum deformation is reduced by 12.29％,and more importantly,the maximum stress of the top beam is reduced to below the yield strength of the material,which lays a good foundation for the safe production of the enterprise.
