Mathematical modelling of vertical and longitudinal-angular vibrations in the composition of the rigidity and damping of the hierarchical parts of the tractor taking into account road impact

The article contains generalized systems of equations describing the vertical and longitudinal-angular vibrations main parts tractor with mathematical model hierarchical linear oscillation tractor, irregularities roads, taking into account rigidity damping. It includes systems: skeleton over propellers a on an uneven road; cab rear walking roads. Equation have also been compiled that describe oscillations uppermost link - seat operator, road. use this original will make it possible to find random unwanted new designed machine design. help optimize their geometric dynamic parameters.
