vibration conveyor

The article deduces an analytical dependence that establishes for a long vibration vehicle a rational length of a working body, as a body with a distributed mass, since it is impossible to match its own frequency of oscillations with the forced.

Problems of determination of optimal geometric and constructive parameters of long-length structures are presented. For example, a longitudinal profile of a complicated section is adopted, its components of the stress state and its own oscillation frequencies are determined. The choice of optimal profile parameters is made for the implementation of structures with minimum equivalent stresses, as well as for ensuring maximum dynamic stiffness.
