Research of the oscillation process of raw cotton during transportation

Abstract Theoretical research of the transportation process of the raw cotton with a tractor-trailer is given in this article. In order to ensure the safe transportation of raw cotton, the law of oscillation of the movement of the trolley on a rough road with a constant speed is determined. A theoretical analysis of the change in the amplitude of body oscillations is given and it is established that a practically constant and significant change in its values occurs only near the resonant frequency. The oscillation frequency in the low frequency zone is determined. In order to remove body oscillations from resonance, a speed limit that satisfies the conditions v < 8.1 l /2 π or v > 8.1 l / 2 π is set. Moreover, the research results of the impact of viscous properties of the transported raw cotton on the amplitudes of oscillations of both the upper and lower boundaries of the body, as well as on the moduli of oscillations and elastic force at various values mod F = C 0 | y 0 − y 1 | of viscous friction are given.
