THE ROTATING AND OVERTURNING PROPERTIES OF TOWED VEHICLES ON CURVES AND UNEVEN CARRIAGEWAYS

DIE WANK- UND KIPPEIGENSCHAFTEN VON SATTELKRAFTRFAHRZEUGEN BEI KUVENFAHRT UND AUF UNEBENER FAHR

In order to extend available methods of calculating the safety of motorized towed vehicles against overturning, a mathematical simulation of the rotating and overturning properties up to the critical range was made on a three dimensional highly realistic model. Upon entry into a curve at 90% of the theoretical overturning speed the overturning process is inevitable within 0.5 seconds. At changes of lane at an excessive speed, before the vehicle overturns, the vehicle goes off course and requires an excessive amount of space and in this case the steering behaviour of the driver is of the greatest importance. Under unfavourable circumstances, e.g. where there is a transverse fall in the carriageway, the critical speed can be lowered by up to 30%. Progressive damping of rotation by means of appropriate stabilizers is advantageous. The influence of the application of rotation damping is shown to be limited. (TRRL)
