摘要

This paper introduces the structural characteristics and screening principle of rotary vibrating screen, and establishes nonlinear equations of rotary vibrating screen in view of the material effects. An approximate solution, material combination coefficient, and material drag coefficient for the nonlinear equations are solved by equivalent linearization method based on nonlinear theory. The selection and calculation on main parameters and a practical calculation example are carried out. It is of guiding significance and reference value for the design of this kind of machinery.
