Experimental and theoretical investigations have shown that to overcome the forces induced as a vehicle turns a sharp corner the power output from the engine must be increased considerably. Steady state power when cornering can be predicted by a simple summation of the work done by the tractive effort in overcoming the rolling resistance, the centrifugal forces and the sbogie slewing moments at each group of axles. Fixed axles with no articulation are the prime cause of the increase in power. Slip angles were calculated and tire wear assessed at the various axles of an articulated vehicle. For long haul operation the effect of cornering will not account for mor than about 3 per cent of the total fuel consumption. (Copyrigh (C) Crown Copyright 1979). (DePo)
