Nonlinear Analysis of Unbalanced Mass of Vertical Conveyer-Elevator

Abstract

The Vertical conveyers have a cylindrical casing, a helical open trough or closed pipe is attached at the outside or at the inside of the vertical tubular casing, along which the load can be transported from the bottom upwards. A vibration-exciting drive is mounted at the top or bottom of the casing to impart to the latter directed vibrations along and around the vertical axis, which cause the load to move upwards along the helix. In this work, nonlinear analysis for the change of the parameters of the motion, stability condition, and the jump phenomena has been shown graphically
