Description: Special Report
Abstract: The drawbar hitch point location has a direct effect on the trim attitude of a vehicle and also influences the net pull developed by a vehicle during a drawbar pull test. These resultshave indicatedan area of study needing expansion: the relationship of sinkage and slip. Slip-sinkage is a factor which cannot be neglected in the analytical evaluation of vehicle performance. The equations relating sinkage, resistance, trim angle and the traction require further development. One procedural modification that could be made when a drawbar pull test was being conducted to obtain validation data would be to locate the tow hitch point at ground level, eliminating the trim attitude caused by the rearward shift of the center of pressure beneath the contact area.
