Optimization Design and Practical Application of Hydraulic Support Shield Beam
The shield beam structure is the main load-bearing structural component of hydraulic supports,and optimizing its design can significantly improve the design level of hydraulic supports.Taking the shield beam of ZY5000/8.5/16 hydraulic support as an example for analysis,based on an overview of the structure of the hydraulic support and shield beam,a simulation model was established using ANSYS software.The analysis found that the safety factor of the shield beam is very high,and there is a lot of room for lightweight design.Selecting 10 key structural dimensions of the shield beam as optimization objects,with maximum deformation and equivalent stress as constraints,and total mass as the optimization objective,the overall mass of the shield beam was reduced by 17.6%through optimization.Deploying the new shield beam in coal mine engineering practice,after a period of application,it was found that the overall operation was stable,verifying the effectiveness of lightweight optimization design.
