| The hydraulic support is one of the key equipment in maintain coal mine safe production.Byfluid pressure in the coal seam roof on the work supporting the safety, this coal miningmachinery is widely used in coal production in order to ensure continuous operation. For coalproduction in the bracket reflects fall apart, crushed, damaged parts and other issues, we take theexample of ZF3700/16/26hydraulic support for the design of the sample type, in order to designits structural and mechanical analysis.In Pro/E environment, a three-dimensional solid model of the stent design is completed forZF3700/16/26hydraulic components of the overall study of the structure and composition. Theequipment of the virtual assembly and interference checking, verify component design, assemblyand movement of feasibility are finished.Useing of Finite element analysis software ANSYS with3D modeling software Pro/Ethree-dimensional modeling and finite element analysis, ZF3700/16/26hydraulic components ofmain bearing of bracket strength is completed. The displacement and stress cloud in different testloading conditions are finished. Based on finite element analysis results,the reasonableness of theoverall stent structure was verified.Aimed by the finite element software ANSYS, The key component of support: top beam,the base, shield beam, the front link, the back link and upright column are finished by dynamicalmodal analysis.Modal simulation results show the most likely location of them and thecorresponding frequency when the support is broken.The ZF3700/16/26type hydraulicsupport modes are obtained and the hydraulic support rigidity check is done.In summary, this is the meaning and value: the ZF3700/16/26bracket for static strengthanalysis and dynamics of modal analysis are completed.The simulation results provides atheoretical basis to optimize the stent structure, improve equipment, selecte reasonableequipment, divise frequency section, and increase the carrying capacity of stent use life. |
