Strength Analysis and Improvement Design of ZY4000 Cover Type Hydraulic Support Base
Taking the base of ZY4000 covered hydraulic support as the research object,the strength analysis of the base was carried out with the help of ANSYS Workbench finite element simulation and analysis software.The results show that there is stress concentration in the bridge position of the hydraulic support base structure,which can not guarantee the reliable work of the hydraulic support base.Comparing and analysing the equivalent stress distribution when the bridge thickness of the hydraulic support base is 25 mm,27 mm,29 mm,31 mm,33 mm and 35 mm,it is known that with the increase of the bridge thickness,the value of stress concentration gradually decreases,and the bridge thickness of 35 mm has the optimal mechanical properties.After the completion of the improvement of the base for test verification,the results show that the application of the improved base,enhance the bearing capacity of the base,reduce the equipment operation and maintenance personnel and costs,improve the reliability of the hydraulic bracket,can create more economic benefits for the coal enterprises.
