Static Analysis and Structural Improvement of Rear Top Beam of Coal Mine Hydraulic Support
Based on the optimization design method and finite element method,the static analysis and structural optimization improvement of the rear top beam of ZCC8800/20/38 hydraulic support were carried out. The results indicate that there is a significant stress concentration phenomenon in the rear top beam,with a safety factor of only 1.22,which is lower than the mechanical industry standard. It is necessary to optimize and improve it. Selecting 9 key structural parameters as optimization objects and using ANSYS software for structural improvement,the maximum stress of the rear top beam was reduced by 19.06％,and the safety factor met the standard. The optimized rear top beam structure was deployed in hydraulic support engineering practice,and during the six-month practical testing,it was found that the effect was very good,the stability of equipment operation was improved,and the failure rate was significantly reduced. This structural optimization and improvement can create good economic benefits for the enterprise.
