Force Analysis and Structural Optimization of ZY5000/15/30 Hydraulic Support Base for Mining
Hydraulic support is one of the most important supporting equipment in mine,and it plays a very important role in coal mining.Support base is the key bearing structure of hydraulic support.In this paper,the ZY5000/15/30 hydraulic sup-port is studied,and the main reason of stress concentration is found by using ANSYS software.Through increasing the thick-ness of bridge plate and reducing the thickness of side plate and rib,the basic structure of hydraulic support is improved.The simulation results indicate that the maximum stress of the base is decreased by 60%,and the maximal deformation is decreased by 20%,which has reached the expected effect,and provides a theoretical reference for the safety production of the mine.
