LATERAL-ACCELERATION EXPERIENCE OF MULTITRAILER VEHICLES IN SERVICE

This paper examines the lateral-acceleration experience of double- and triple-trailer vehicles in regular commercial service. The test fleet included 17 tractors, 86 semitrailers, 28 C-dollies, and 16 A-dollies spread among five commercial trucking fleets. Data were gathered during 350,000 miles of travel over a period of eight months. Lateral acceleration signals were processed in the frequency domain to compare the rearward amplification qualities of A-trains and C-trains. Results from this normal operating environment agree remarkably well with measurements made previously in severe maneuvers conducted at the test track or in vehicle simulations. Histograms of lateral acceleration experience are also presented. A rearward-amplification-like measure obtained in the time domain collaborates the findings in the frequency domain. Time-domain data also suggest that drivers take note of the lateral performance qualities of their vehicles and modify their driving behavior accordingly.
