Strength Analysis and Optimal Design of Coal Mining Machine Connecting Frame
Aiming at the phenomenon of stress concentration in the connecting frame of MG500/1180 coal mining machine,the strength analysis of the connecting frame of the coal mining machine was carried out by using ANSYS Workbench simulation and analysis software,and the results show that there is stress concentration in the position of the lugs on the coal wall side of the connecting frame.After that,the thickness of the rib plate on the coal wall side of the connecting frame and the thickness size of the rib plate on the mining side were optimized and designed,and the results showed that the stress concentration of the connecting frame was improved,and the application results showed that the connecting frame worked reliably after optimization,and the cumulative wear of the pin on the coal wall side of the connecting frame and the position of the connecting frame after optimization was small compared with that before optimization of the connecting frame in the same period,and the optimization effect was remarkable.
