Computer Simulation of Vibratory Transport

It is difficult to simulate properly the vibratory transport. One does not know how to describe the influence of a bulk material layer on the transporting trough. There are few approaches, but none is satisfactory enough. Author proposes to apply a model of a dynamic dumper which simulates periodical collisions between material and the trough, when they are coming to the contact after the free flight of material above the trough. Computer calculates average speed of transported material and handling output as well. When the quantity of material on the trough is known, then the force of the dynamic dumper could be calculated. This force together with the exciting force of the vibrator are introduced into equations describing the model of a mutti- mass conveyor. The basic goal of simulation is to find the required exciting force and the power of an electromagnetic vibrator. it is possible to find optimal data of designed elements of vibratory conveyors as well.
