Optimization of Lug Seat and Bending Angle of Rocker Arm Shell of Coal Mining Machine
In order to further improve the cutting performance and production safety of coal mining machine,it is urgent to optimize the parameters of rocker arm shell to improve its reliability.First of all,according to the production parameters of the cutting section of coal mining machine and its production requirements of the working face,the load of the cutting section of coal mining machine in the X,Y and Z directions is calculated under the actual working conditions,based on which the finite element analysis is carried out on the cutting section of the coal mining machine,and the weak part of the rocker arm ear seat is grasped;and then the optimization of the rib plate position and the bending angle is carried out based on the fatigue analysis and the method of the effect of coal loading,which is the best solution for the subsequent cutting section of coal mining machine.Then the parameters such as rib plate position and bending angle were optimized based on fatigue analysis and coal loading effect method,which laid a theoretical foundation for the optimization of the cut-off part of coal mining machine.
