energy dissipation

This study presents the development and dynamic analysis of a mechanical model representing a multi-component vibratory system consisting of a feeder, a vibratory transporter, and a conveyor-separator. The main goal is to simulate the oscillatory response of a three-mass separator excited by a crank-slider mechanism and analyse its efficiency, focusing on the working body responsible for material separation. The vibratory system is modeled using a set of second-order linear differential equations derived via Lagrange’s second kind formulation.

The purpose of the paper. Substantiation of structure (design), parameters and operation modes of the improved vibratory finishing machine. Analysis of dynamical processes which occur during “lap over lap” dressing. Investigation methodology. Mathematical model of motion of the mechanical system of vibratory finishing machine was developed on the basis of Lagrange differential equations of the second order. For the purpose of describing friction between the working surfaces of the laps, the Coulomb friction model was used.
