GARCIA DE LA FIGAL COSTALES, Armando Eloy y DIEGO NAVA, Fidel. Stability analysis of the plow "FDN" animal traction . Rev Cie Téc Agr [online]. 2010, vol.19, n.1, pp. 95-97. ISSN 2071-0054.
For the analysis by the methods of the static of a plow of animal traction -manufactured FDN in Oaxaca, Mexico, a system of forces is used in the longitudinal-vertical plane of movement, applied in specific points of the organ of work of the same one, to 1/3 and 1/4 of its work depth, whose values vary from 440 to 1 200 N and of 20 to 260 N for the horizontal force Rx and the vertical Rz, respectively and their dimensions, weight, center of gravity and point of application of the shot, which is inclined ? of 200 and 180 regarding the horizontal one are known. The results demonstrate that for the conditions signal, this plow of animal traction can be before in static equilibrium-as first principle of the stability of the mobile systems outlined by Lyapunov-if they are regulated or the vertically point where the plow is coupled to the helm or the longitude of the arm of work organ regarding the chassis of the plow, or both. Displacing vertical necessary calculated they vary in: from 49,39 up to 163,33 mm, for when ?=180 and of 11,16 to 128,24 mm for ?=200. Failure of the above realization, would imply that the chassis of the plow would rotate an angle ? of 4,760 in clockwise, until-1,020 in against, for ?=180 and of 2,760 in the address, until-1,50 anticlockwise, for ?=200.
