Research on the Optimal Design of Hydraulic Support Cover Beam Structure
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％.
