Finite element analysis and optimization research of ZF3700/16/26 hydraulic support base
The finite element model of ZF3700/16/26 hydraulic support base in Taishan Long'an Coal Industry was established by using SolidWorks and ANSYS Workbench software.Through analysis,it was found that the maximum stress and maximum displacement deformation were 515 MPa and 4.14 mm respectively,and the corresponding safety factor was only 1.07,which had potential safety hazards.In order to solve this problem,the optimization and improvement work is carried out with the bridge width,the height of the column socket and the thickness of the ear plate as the optimization objects.The maximum stress and maximum displacement deformation after optimization are reduced by 29.4％and 21.01％respectively,and the safety factor is increased to 1.51.The optimized base is applied to the engineering practice of Taishan Long'an Coal Industry.After 6 months of field application,the expected effect is achieved.The service life is expected to be extended by about 15％,which can create good safety and economic benefits for the enterprise.
