Dynamic Characteristics of Vibrating Screen with Determinate Structure and Statically Indeterminate Structure
Analyzed vibrating screen’s dynamic characteristics of determinate structure and statically indeterminate structure, calculate natural frequency, natural vibration mode and dynamic response based on finite element technology. The results show that the vibrating screen’s structural strength is increased and the natural frequency of bending and twisting deformation is improved by means of the adoption of statically indeterminate structure. The natural frequency is far from work frequency which means the structure can avoid resonance effectively. Statically indeterminate structure provides a big structure intensity and stiffness to meet vibrating screen’s needs in the design process.
