polyharmonic oscillations

Optimal angles for lifting of unloading cargoes during irrigation vibration transport with polyharmonic normal oscillations

Vibratory conveying with harmonic longitudinal and polyharmonic normal oscillations of vibratory conveying device in non-jumping modes is considered. Optimal values of inclined track angles are determined on the condition of the piece goods lifting at a certain height in the minimum time. It is shown that optimal inclined track angle depends on the number of harmonics of polyharmonic normal oscillations and coefficient of friction.
