Equations of motion for a conveyor driven through a spring carrying a
load have been derived taking into consideration the friction between
the conveyed load and its vibrating table. A quick-return mechanism is
used to drive the table of the conveyor through a spring. Effect of v
elocity and the time ratio of the driving mechanism, spring stiffness
and the damping criterion of the suggested system on the relative moti
on of the conveyed load with respect to the table are studied. (C) 199
