ROLLING RESISTANCE OF OFF-ROAD VEHICLES

The rolling resistance (RR) of vehicles operating off-road is a significant factor in estimating the haul time and productivity of earthmoving vehicles. An examination of tire performance tests shows that RR of free-rolling tires is often underestimated and the RR of driven tires varies with the applied torque. The use of an analytical tire-soil interaction model is a rational method of estimating the RR under various conditions. Performance data sets obtained from this model can be used in conjunction with rimpull-speed relations supplied by the manufacturers to make unbiased comparative analyses of various candidate vehicles for a given task and to improve haul-time calculations by rimpull-dependent RR values in vehicle simulation programs.
