Abstract: The dynamics and modal characteristics are important basis for the stable operation of vibrating screen. A multi-body dynamic model of vibrating screen was established based on ADAMS, and the laws of change in the center of mass and the dynamic response of the vibration isolation system were obtained. The amplitude-frequency response results of acceleration under varying stiffness and damping coefficients were compared and analyzed, providing a crucial foundation for enhancing vibration isolation performance. The vibrating screen was analyzed for its modal characteristics using ANSYS, and the natural frequencies and vibration patterns were investigated. The distribution and main causes of the maximum resonance displacement were discussed. Drawing on the results of stress and modal shapes, the strength of the vibrating screen was significantly enhanced through multi-objective optimization methods without increasing its weight. The findings indicate that the optimized structure can achieve a 32.2 % reduction in peak stress.
