Stable motion of transport vehicles with allowance for the steering system vibrations
- S.P. Timoshenko Institute of Mechanics, Kiev (Ukraine)
A new mathematical model is developed for the plane-parallel motion of a system consisting of the frame of a vehicle and a steering system that controls the motion. The stability of straight-line motion is investigated. In most studies on the stability of the straight-line motion of a motor vehicle and a tractor-trailer unit it is assumed that in disturbed motion the driver keeps the steerable wheels in a neutral (unturned) position: the angle {theta} through which the wheels are turned about the axis of the steering knuckle pivot is zero. The validity of the assumption that {theta} = 0 can be argued in only one way, i.e., the torsional stiffness {Kappa} of the steering system is fairly high: if {Kappa} {yields} {infinity}, then {theta} = 0. For finite values of {Kappa} we have {theta} = 0. In that case the variable {theta} is determined by its differential equation, i.e., the number of degrees of freedom of the vehicle increases by one. The dynamic behavior of vehicles in this formulation is considered in this paper.
