A unique 400 electrical horsepower chassis dynamometer capable of rolling five loaded axles of any wheelbase at speeds up to 90 mph provides the environment for demonstrating tractor-trailer ride dynamics. An actual tractor cab pitch problem occurring in the cruise speed range is described. Dynamometer data gathered during the definitive stages and from attempts to improve tractor ride by changing trailer geometry are presented.
