Impact of dynamic wheel load on roadway infrastructure sustainability

Integrated Vehicle–Tire–Pavement Approach for Determining Pavement Structure–Induced Rolling Resistance under Dynamic Loading

“…In this study, a 21-degrees-of-freedom full semitrailer-truck model was used to simulate the truck dynamic vibrations, and road roughness profiles were used as inputs (Figure 2). The model was initially developed to predict roughness-induced dynamic wheel loads and roughness-induced energy consumption of heavy trucks ( 18 , 29 , 30 ). The truck model developed allows calculating the dynamic wheel loads of a five-axle semitrailer truck excited by road roughness profiles at different driving speeds and truck dynamic properties (e.g., geometry, mass, stiffness, and damping).…”

“…The truck model and its parameters have been described elsewhere ( 18 , 29 , 30 ), and thus only the main mechanical properties are presented in Table 1, where 1 kg = 2.2 lb, 1 m = 3.28 ft, 1 kN/m = 68.5 lbf/ft, and 1 kN-s/m = 68.5 lbf-s/ft. These parameters represent a large articulated truck with a fully loaded trailer.…”
