Abstract
Specifies a test procedure to determine the damping characteristic of trailer oscillation excited by a defined steering impulse. Measurements are made of steering-wheel angle, forward velocity, lateral acceleration of the trailer, articulation angle between towing vehicle and trailer. If non-periodic instability is of interest, a steady-state circular test may be performed in accordance with annex C.
