摘      要：The double drum coal shearer is widely applied for the underground coal exploration in the mining *** vibration and noise control are significant factors for the stability design of the double drum coal *** this paper,the vibration properties of a double drum coal shearer are firstly *** horizontal,transverse and torsional vibrations of the motor body and the angle displacements of the rockers are taken into *** walking units and the hydraulic units are modeled by the stiffness-damping *** nonlinear equation of motion of the double drum coal shearer is established by applying the Lagrange’s *** nonlinear vibration response of the system is calculated by using the Runge Kutta numerical *** effects of the shearing loads,the equivalent damping and stiffness of the walking units,the inclination angels of the rockers and the equivalent damping and stiffness of the hydraulic units on the vibration properties of the system are discussed.

主 题 词：coal shearer vibration multi body dynamics transient response
