Basic principles for the approval of elective parameters of the adaptive surface of collected vehicles of special purpose

Abstract

The use of wheeled vehicles of special purpose systems pidresoryuvannya relevant class production cars leads, at best, with output down some of its elements. Therefore, there is a need to create a system of sprinkling with such power characteristics, which on the one hand would as much as possible satisfy the ergonomic conditions, and on the other hand - provided special characteristics (stability of motion, permeability, controllability, high efficiency of driving east, maneuverability when changing the location of personal warehouse). To substantiate the choice of the main power parameters of wheeled vehicles with an adaptive sprinkler system, a mathematical model of vertical fluctuations of its submersible part during a movement along the path with an arbitrary placed system of inequalities is constructed. It represents non-autonomic nonlinear differential equations of the second order. For the latter, a method for constructing the first approximation of the asymptotic solution is developed. The method is based on the general provisions of perturbation methods and the idea of using special periodic Ateb-functions for constructing the solutions of some classes of nonlinear differential equations. In the aggregate, the above resulted in obtaining analytical relations that describe the determining parameters of oscillations of the submerged part of the vehicles during the movement by means of a system of randomly placed inequalities. By analyzing the latter, in particular, it was found that the amplitude of the output of single inequalities for larger lengths of the latter is greater, and for smaller inequalities at higher speeds of the KTZSP. The obtained analytical dependencies can serve as the basis for the choice of the main power parameters of an adaptive suspension, which would minimize the dynamic loads on people and goods transported.
