Research on Vibration Characteristic Analysis and Optimisation Design of Rocker Arm of Coal Mining Machine
Taking MG620/1660-WD coal mining machine as the research object,combining with the dynamic load characteristics of the coal mining machine in the process of daily work,we analyse and optimize the dynamic characteristics of its force situation,increase the intensity of its use,and realize the change of the second-order modal state,so as to increase the stability of the rocker arm of the coal mining machine.Finally,the feasibility and reliability of the model is verified by carrying out the vibration test of the rocker arm of coal mining machine.
