Design and Mechanical Analysis of Four-Link Mechanism of Hydraulic Bracket for Medium and Thick Coal Seam in Coal Mine
In order to further investigate the hydraulic support four-link mechanism suitable for mining medium-thick coal seam in coal mines,the geometric drawing method is applied to select and design the four-link mechanism that meets the requirements and clarify the main parameters of the link structure.After that,the finite element analysis method is applied to the four-link mechanism to clarify its stress distribution,so as to put forward the possible optimisation path initially,which provides certain reference for the subsequent optimisation and field testing of the mechanism.
