Simulation Analysis of Rocker Arm Connecting Pin Load of Coal Mining Machine
Numerical simulation software was used to analyse the stress-strain cloud diagrams of one section,two sections of connecting pins and one section of connecting pins under the working conditions after the addition of connecting frame,and it was found that the maximum stress value of the two sections of connecting pins on the side of connecting pins close to the coal wall was 3.558 4 MPa,and the maximum strain value was 1.923 1 × 10-5 mm,which was the maximum value in all three cases,and at the same time the stress and strain of one section of connecting pins were the smallest,and at the same time the stress on the side of connecting pins at the coal wall was the largest.At the same time,the force and strain of one section of the connecting pin is the smallest,and the force and deformation of the coal wall side of the connecting pin is obviously larger than that of the side of the hollow area,which provides a certain reference for the optimisation of the connecting pin of the coal mining machine in the future.
