title: Reducing the Energy Intensity of Grape Vine Shredding Using a Picker-Shredder
abstract: The study aimed to substantiate approaches for lowering energy intensity and to determine the technical and technological performance parameters of operating modes for the shredding unit of a grapevine picker-shredder. The analysis included calculations of the angular velocity of a shredding knife hinged to a drum and the knife’s destructive velocity during impact on the vine. To determine the coordinates XC and YC of the center of gravity C and the moment of inertia J of the knife, the authors
