Truck Drag Components by Road Test Measurement 640794

Road test methods are described by means of which the total drag force, the air drag force, the tire drag force, and other drag components of a truck can be measured. The road tests consist of coastdown experiments over a wide speed range at several loads. Independent measurements of tire drag force and air drag force demonstrate that these road data are essentially correct. Examples of results of the road test method are shown for a few large transport trucks.
