The Static Stability of Articulated Commercial Vehicles
TLDR
In this article, a review of the state-of-the-art results in extending conventional analysis techniques to the treatment of highway trains is presented, that is, to heavy trucks with multiple articulation points and suspensions with multiple axles.Abstract:
SUMMARY This review of the state of the art emphasizes recent results that have been obtained in extending conventionalanalysis techniques to the treatment of “Highway Trains”, that is, to heavy trucks that have multiple articulation points and employ suspensions with multiple axles. Equations of motion applicable to the equilibrium turning performances of articulated vehicles are examined with respect to using analysis techniques involving steering gains, understeer gradients, effective wheel-bases, handling diagrams, and critical speeds. These examinations provide the basis for in sights into simplified approaches for understanding the steady turning mechanics of articulated, multi-axle vehicles riding on pneumatic tires.read more

Directional performance issues in evaluation and design of articulated heavy vehicles
TL;DR: A review of the dynamics of heavy road-vehicle systems emphasizing directional performance is presented in this paper, where the authors present information on the following topics: why are articulated vehicles used; units, hitches, and combination vehicles; multiple axle suspensions and steering systems; important performance issues; models and simulation tools; and controlling directional performance.

Simplified Analysis of the Steady-State Turning of Complex Vehicles
TL;DR: In this article, a more complex vehicle whose slip angles depend on lateral acceleration plus another motion variable was examined, and a general analysis of the complex vehicle together with analyses of linear and nonlinear trucks provided new insights into understeer/oversteer quality of all vehicles.

Generalised multi-axle vehicle handling
TL;DR: In this paper, the two-axle bicycle model and associated basic concepts of vehicle handling are reviewed and used to introduce minor changes in convention from the literature and a generalised model is developed that produces dynamic equations of motion by inspection for a vehicle with an arbitrary number of steerable and non-steerable axles.

The cornering compliance concept for description of vehicle directional control properties
R. T. Bundorf,R. L. Leffert +1 more
TL;DR: In this paper, a concept for combining most vehicle design parameters into two terms, front and rear cornering compliance, is proposed, and the results indicate that the cornering compliant approach is reasonably accurate.

The Influence of Size and Weight Variables on the Roll Stability of Heavy Duty Trucks
TL;DR: In this paper, the roll stability of heavy-duty trucks and truck combinations is discussed both on the level of the fundamental mechanics of vehicle response and from the viewpoint of the quantitative influence of size and weight variables.
Influence of size and weight variables on the stability and control properties of heavy trucks - volume ii. final report
TL;DR: In this article, the influence of variations in truck size and weight constraints on the stability and control properties of heavy vehicles was determined by means of both full-scale vehicle tests and computer simulations.
