Abstract

Significant reduction of processing time, fuel storage and electric supply, as well as product quality improvement, decreased costs for maintenance and environment protection and heat transfer process intensification can be obtained by applying vibrations to process bulk and rod materials by heat treatment. This paper presents the results of theoretical studies of the vibration machine dynamics under diverse types of working body vibrations and drive quantity. Based on the results of differential equation solutions, amplitude parameters of the steady-state oscillations of the machine working body have been obtained by moving the working chambers points considering the installation angular oscillations. It has been established that the amplitude of the point vertical oscillations is equal to the amplitude of the wheel oscillations of the installation gravity centre. To determine rational parameters according to the requirements of the processing materials technology appropriate vibration trajectories of the vibration machine points have been obtained. The design of the vibration device allows adjusting the oscillation amplitude and the trajectory nature of the installation working body points in a wide range.

Keywords: rod or bulk material, motion kinematics, processing, vibrating machines, vibration trajectories, liquid, or air environment
