Moreover, as the road surface roughness affects the vehicle dynamic forces, an efficient monitoring of pavement condition is also necessary to achieve this aim. This paper uses a novel algorithm to identify the dynamic interaction forces and pavement roughness from vehicle accelerations in both theoretical simulations and a laboratory experiment; moving force identification theory is applied to a vehicle model for this purpose. Theoretical simulations are employed to evaluate the ability of the algorithm to predict forces over a range of bridge spans and to evaluate the influence of road roughness level on the accuracy of the results. Finally, in addressing the challenge for the real-world problem, the effects of vehicle configuration and speed on the predicted road roughness are also investigated in a laboratory experiment.||Type of material:||Journal Article||Publisher:||International Association for Sustainable Development and Management||Copyright (published version):||2012 International Association for Sustainable Development and Management||Keywords:||Acceleration;dynamic axle forces;inverse dynamics;laboratory experiment;pavement roughness;vehicle-bridge interaction||Language:||en||Status of Item:||Peer reviewed|
