Research on Cutting Teeth Form's Influence on Coal Shearer Vibration Characteristics

Abstract:

Electric traction coal shearer is widely applied by the coal industry in present China. Its stable and safe working status is a key factor to guarantee the stability and safety of colliery’s production. This paper aims to analyze coal shearer’s fuselage vibration characteristics under different forms of cutting teeth conditions via actual measurement in working face and try to work out different teeth forms’ influence degree on shearer’s fuselage vibration. The research have surely drawn some significant conclusions, which will provide theoretical guidance for industrial practicing and help to avoid body’s damage caused by the fuselage vibration.
