Abstract: In research on the vibration screen mechanism this paper presented an approach of analysis and obtained the first approximate solution of mechanism in forced vibration, considering the mass variation which results from materials jumping. The study is based on the theory of variable mass kinetics’ and nonlinear vibration.
