Analysis of productivity and cost of forestry transportation : Part three: theoretical analysis of the impact of vehicle operating conditions on power losses [and] experimental determination of rolling and air resistance forces
The mathematical and graphical relationships between vehicle operating conditions on power losses have been developed in the continued definition of a computerized data base by which the efficiency of transportation systems can be measured and optimized. To demonstrate the practical application of this research work, the savings possible in a realistic haul operation have been calculated.
