| Abstract: |
| The dynamic model of inertial vibrating crusher is established, in which relative parameters are taken into consideration; the coupling relations of assemblies are discussed, and appropriate calculation method is chose to solve the vibrating differential equation. The results show that the horizontal vibration and swing are large when starting the machine. As two rotors get a certain angular velocity, the vibrating system can be stable, the horizontal vibration and swing vanish, and the vertical vibration is stable. When the system is stable, though two rotors’ motors and damped coefficient are different, their angular velocities tend to be equal; and two jaws’ damped coefficients and stiffness coefficients are different, the swing phases can be different. This method can be used to discuss the effect of one parameter on the system. |
