ABSTRACT
Vibration is an inevitable phenomenon in the coal cutting process and severe vibration leads to efficiency loss for cutting equipment. To understand the impact of vibration on cutting equipment and explore the measures to improve the stability, the dynamic response of cutting equipment is analyzed. The shearer drum, which always undertakes coal cutting task and is the vibration source in working process, is established with finite element method and the relations between cutting performance and vibration characteristics are analyzed. Hydraulic system, vulnerable to external shocks, is also established and the dynamic responses of hydraulic piston under different working stages are analyzed. In the frequency domain analysis on cutting load, results show that a vibration signal with higher amplitude appears, which is consistent with the drum vibration frequency. It demonstrates that drum vibration happens under impact load, especially during height adjustment stages. The research provides the methods for vibration reduction and would be helpful for improvement of shearer reliability
