摘要

A 8 × 8 vehicle has better performance in terms of its obstacle crossing capabilities and off-road manoeuvring. In this study, a comprehensive multi-body model of the vehicle with multi-axle steering was developed. Vehicle handling is studied by first quantifying the steady-state behaviour of vehicles and then relating steady-state principles to transient dynamics. Vehicle handling characteristics depends on suspension and steering linkages configuration, tyre properties, sprung/unsprung mass of vehicle and road loads. A MBD model for handling was developed and steer angle versus lateral acceleration was plotted. Handling characteristics of a multi-axle vehicle were carried out objectively as per SAE test procedure and the model was validated through conduct of actual experiments. It was concluded that understeer characteristics as desired were achieved.
