OPTIMAL PHASE DIFFERENCE BETWEEN LONGITUDINAL AND NORMAL OSCILLATIONS WITH PIECEWISE CONSTANT ACCELERATION DURING VIBRATORY CONVEYING

The paper is dedicated to researching vibratory conveying with longitudinal harmonic oscillations and normal oscillations with piecewise constant acceleration (two-component vibration) of conveying track in non-hopping modes of moving when particles slide without detachment from the surface when maximal normal acceleration that does not exceed the gravitational acceleration.

Optimization of vibratory conveying upward by inclined track with polyharmonic normal vibrations

The paper is devoted to the research of vibratory conveying of piece goods along an inclined track, performing harmonic longitudinal and polyharmonic normal vibrations. It is considered the conditions of reaching maximum conveying velocity at specified values of frequency and amplitude of longitudinal vibrations – the conditions of maximum dimensionless conveying velocity, depending on several dimensionless parameters in the moving modes without hopping.

Prospects of Use of Vibratory Devices with Electromagnetic Drives for Massive Piece Goods Conveying

Vibratory conveying devices with electromagnetic drive are widely used in the different branches of industry. As a rule, they deal with relatively small piece goods and are not suitable for conveying of the large massive goods with high productivity. The conveying of massive piece goods needs the using of non-hopping modes of moving in which the high velocity can be reached only in the case of non-linear vibration trajectories of the conveying track, for example elliptical trajectories.

The Influence of the Ratio Between Kinetic and Static Frictional Coefficients on the Conveying Velocity With Elliptical Oscillations

The influence of the ratio between kinetic and static frictional coefficients on the dimensionless velocity coefficient is considered for non-jumping vibratory conveying modes with elliptical oscillations. It is shown that with decreasing of this ratio the value of velocity coefficient decreases. This decreasing is less essential with the track inclination angle increasing and it almost disappears with the extreme inclination angles.
