Numerical example of determining the trajectory of a heavy point moving with friction along a helical surface with a curved generatrix (To the theory of a spiral separator)

Abstract

The theory of a spiral separator is based on the study of the movement of a heavy point along a rough helical surface. The article carries out the integration of differentiated equations of motion of a heavy point along a helix on a rough surface, which has a curvilinear generatrix. As Prof. M.I. Akimov points out, this surface can be used to build sorting machines. The movement of a heavy point along this surface is carried out at a vertical speed, regardless of the helical line of movement.
