Popova A. Geometric modeling of the radial profile of the cars working blades for transporting soil, by throwing

Dissertation for the degree of Candidate of Technical Sciences, specialty 05.01.01 - applied geometry, engineering graphics. - Kyiv National University of Construction and Architecture, Kyiv, Ukraine, 2014. The thesis is devoted to geometric modeling of the processes associated with the transport of particles of solids at a distance. While working on dissertation research the main goal was achieved: have been developed and implemented the comprehensive model calculating profile shape throwing blades with regard to the movement of soil particles as in a pan, and in the air with regard to the description of the spatial shape of blades provided their definition proposed method. The main scientific value of the work is to find the optimal way to form a curved blade, based on the solution of the problem of polar brahistohrons for material particle that moves under the influence of centrifugal force and inertia into account power of friction, allowing the geometric means of visual representations to explore the influence of the main design parameters of the scapula and rotor parameters on the east soil particles with shovels and make simulation trajectories and range soil particles with random parameters.
