7-DOF NONLINEAR VIBRATION ANALYSIS OF SHEARER UNDER CONDITION EXCITATION
In order to study the influence of shearer traction speed on its dynamic characteristics,using the three-axis force of pick as the description of cutting incentive of shearer pick,Hertz contact theory was used to describe shearer’s smooth boot brace stiffness and damping. Nonlinear model of meshing...
