APPLICATION OF GENERAL RIGID BODY DYNAMICS TO VEHICLE BEHAVIOR

This paper is concerned with the application of a 4x4 matrix method to simulating the behavior of articulated highway vehicles. the method requires only that a model of the vehicle be adopted and that data concerning the characteristics of the model be specified - the digital computer is used to reporesent numerically and to solve exactly the differential equations that govern the behavior of the vehicle model. The method is applied to simulating the behavior of several articulated vehicles. Results are first given for the predicted behavior of a tractor-semi- trailer truck. These results are compared with those obtained from a previously developed tractor-semitrailer model. The comparison leads to the discovery of an error in the previously developed model. When the Effects of this error are eliminated, the results obtained from both models are nearly indentical. The method is then used to obtain predicted behavior of several different articulated vehicles for a cornering maneuver with and without braking. Results of a no-braking case and of a braking case for a triple (tractor with three trailers) are given.
