Bezditniy A. Discrete variational geometric modeling based on geometric ratios in dot calculation of Balyuba-Naydysh

Object - geometrical parities VDGM; methods of analytical, descriptive and projective geometry, dot calculation, VDGM, computer methods of calculation and the image of geometrical forms; theoretical and practical results - the way of construction of sections surface channels is received on the basis of a combination local simplex with continuous arches of contour, ways of construction are considered and the equations of segments surface channels with directing arches of contour are received on the basis of the developed structures, process of separation of grain weight for a crusher A1-DM2R-22B is advanced; scientific novelty - means of dot calculation formalize the equation of a flat continuous arch of contour with tangents in initial and final points for rectangular and not rectangular simplex; within the framework of dot calculation are received and theoretically proved interpolar the circuits based on algorithms VDGM; The equation is received and geometrical properties of a surface of rotation which meridian is the arch semi-cycloid are investigated; the way of drawing up of system of the equations of a segment surface channels with replaceable and constant structures is developed; a degree of introduction - private enterprise " Savenko V.V. ", a society with limited liability "SPP" LANA ", in educational process Taurian State Agrotechnical University; sphere of use development of ways of designing of discretely submitted curves and surfaces with the purpose of association variational discrete geometrical modelling with dot calculation for reception of the new effective modelling device.
