The Modal Characteristics of Circular Vibrating Screen and Kinematics Analysis

The virtual prototype of circular vibrating screen was Established, and the overall structure and working principle of the device were described in detail.The natural frequency of circular vibrating screen was obtained by using finite element analysis software ANSYS to modal analysis,which can provide theoretical basis for the design of vibration frequency and avoid resonance , while using ADAMS software to simulation of the model and analysis to achieve ideal screening effect rotation speed, which can provide reference and basis for the follow-up design and product improvement, and also has a reference value to other vibration machinery research.
