Due to the fact that the technological process of separation of loose (or granular) material with the help of vibrating sieves is used in various fields of agricultural production, there is a need for its mathematical description. The phenomena of contact interaction are one of the most interesting problems of molecular dynamics studies of granular gas. The aim of the research is to conduct a physical and mathematical analysis of the contact interaction of the vibrating sieve with particles of bulk material. As a result of the studies, equations of the total contact force between the particle and the sieve are established at different positions relative to the sieve opening. A model is developed for determining the reduced sieve opening.
