DIRECTIONAL DYNAMICS OF MULTI-ARTICULATED HEAVY TRUCKS EMPLOYING CONTROLLED STEERING OF DOLLY WHEELS --THE DYNAMICS OF VEHICLES ON ROADS AND TRACKS. PROCEEDINGS OF THE 10TH IAVSD SYMPOSIUM, PRAGUE, CZECH, AUGUST 24-28, 1987

Rearward amplification is a problem of special concern for multiple articulated commercial vehicles. This paper has examined several types of dollies which alleviate this problem. A generalized model of the double trailer combination vehicle was presented. By adding special equations of constraint and/or special dolly tyre steering functions, the model can be modified to represent vehicles incorporating several different types of dollies. In the case of simple drawbar dollies, the model decouples at the pintle hitch connection between the tractor semitrailer and the full trailer.. the nature of the closed form solutions which have been obtained for such cases are discussed. The concept of the "steer point" is presented. This concept serves to clarify the influence which steering the tyre of the single drawbar dolly has on the dynamic performance of the vehicle. Useful closed form solutions have not been obtained for certain dolly types. Numerical results, derived from simulation, are presented for such cases.(a) for the covering abstract of the conference see IRRD 813891.
