摘要：The effects of bolter arm on the roadheader stability are studied. According to the mechanical structure of the bolter arm, a vibration model is established, and the model is imported into Simulink for simulation. The frequency response of each step of the roadheader is obtained. The correctness of the vibration model is verified by comparison with the theoretical value. Then, the vibration responses of the roadheader center of gravity in X/Y/Z directions are simulated, and the stability of bolter arm in the working process is studied.
