Influence of speed on concrete agitator vehicle stability.
Concrete agitator vehicles have a relatively high centre of gravity and are therefore exposed to a risk of rollover. The stability of concrete agitator vehicles is also affected by the movement of the concrete in the rotating barrel. This report describes a study into the influence of speed and load on concrete agitator vehicle stability, using vehicle testing and computer based modelling.
It was found that (a) a rotating barrel decreased performance of the concrete agitator vehicles in static rollover threshold and load transfer ratio performance measures when compared to a stationary load, and (b) speed, modelled with the vehicle travelling through a roundabout, had a significant influence on the likelihood of rollover.
