Mechanical design vibrations of shovel pipe - traffic flow grain: theoretical analysis

Researched fluctuations carrier pipe coulter seed drill which moves along the seed crops and the impact on them basic physico-mechanical and geometric characteristics, method consolidation and the relative speed of the grain along the pipe to frequency response of its fluctuations. It remains open problem analytical study of dynamic processes,characterized by longitudinal movement of the light bending rigidity. To solve the problem, an approach that takes into account,the amount of relative movement of grain in the pipe is relatively small quantity with the movement of the pipe during its bending vibrations and continuous speed grain flow tube changes slowly. To solve sex problem in principle odnochastotnosti used in nonlinear vibrations systems with concentrated masses and distributed parameters and asymptotic methods of nonlinear mechanics. The study of mechanical vibrations pipe system - moving stream of grain was reduced to the construction and analysis solution of differential equation for the boundary conditions.
