Determination of optimal conditions of sunflower harvesting with a combiner with a transverse rotor

The system of determination of optimal parameters for sunflower harvesting with a combiner with a transverse rotor is presented. It is based on two points: on a calculated model of forced oscillations of a sunflower transported with a transverse rotor and hit by its roll, and an analysis of a spectrum of own oscillations of mature sunflower. An estimation of influence of a roll shaft speed and its step size on intensiveness of sunflower forced oscillation during its interaction with a transverse rotor.
