Strength Analysis and Optimisation Design of Coal Mining Machine Rocker Arm Shells
Aiming at the problem of cracking at the rib plate position in the rocker shell of coal mining machine,the strength analysis of rocker shell was carried out by using ANSYS Workbench simulation and analysis software with the rocker shell of J71A thin seam high-power coal mining machine as the object of research,and the results showed that the stress concentration at the rib plate position of the rocker shell was the main reason for its fracture.The structural improvement of the rocker arm shell is completed by increasing the size of the rib plate,and the improved rocker arm shell meets the requirements for safe use.The application of the improved rocker arm shell reduces the failure frequency of the rocker arm shell,improves the effective working time of the coal mining machine,reduces the operation and maintenance cost of the coal mining machine,reduces the cost of coal,improves the coal production,and creates more economicbenefits for the coal enterprises.
