Comprehensive Measurement of Ride of In-Service Trucks 810045
This paper summarizes a comprehensive research program of the ride qualities of long-haul trucks. Factors are identified which contribute significantly to differences in ride quality between various truck models and configurations over a range of actual operating conditions. Detailed measurements of six floor and seat accelerations and driver and passenger ride ratings were made on ten in-service trucks over five segments, ranging from “smooth” to “rough,” of a typical California freeway. The experimental methodology is reviewed and validated, and example data and preliminary comparisons between the objective and subjective measures are presented.
