This report summarizes a three-year project to characterize and improve the ride quality of the Department of Energy (DOE) tractor/trailer. A high-fidelity computer model was used to simulate the vibrational response in the passenger compartment of the truck due to a common roadway environment. It is the intensity of this response that is indicative of the ride quality of the vehicle. The computational model was then validated with experimental tests using a novel technique employing both lab-based modal tests and modal data derived using the Natural Excitation Technique (NExT). The validated model proved invaluable as a design tool. Utilizing the model in a predictive manner, modifications to improve ride quality were made to both the existing vehicle and the next-generation design concept. As a result, the next-generation fleet of tractors (procurement process begins in FY98) will incorporate elements of a successful model-based design for improved truck ride.
