Research on Optimization and Improvement of Coal Mine Hydraulic Support Structure Based on Simulation
As an important component of the"three machines"equipment in coal mine working faces,the stable and safe operation of hydraulic supports has a direct impact on the production quality and efficiency of coal mines.A simulation model of the ZY2800/13/28 shield hydraulic support was constructed using SolidWorks software as the research object.It was found that there was stress concentration in the vicinity of the ear plates of the hydraulic support top beam and shield beam.By improving the connection form of the ear plates and adjusting the thickness of the shield beam,the hydraulic support structure was optimized,resulting in a 17.33%reduction in the maximum stress of the hydraulic support.Practical application has found that the new hydraulic support operates well and its service life can be extended by 1～2 years,with significant economic and safety benefits.
