Mechanical analysis of full-scale accelerated pavement loading facility based on multi-body dynamics

摘要: ABSTRACTIt is intended that the pavements need to be designed accomplish better performance due continuous increases of traffic volumes, vehicle loads and tyre pressure, especially for channelized traffic. To achieve this objective, method accelerated pavement testing used directly optimize asphalt design. Therefore, quality facility plays an important role in optimizing In order improve success rate facility, mechanical analysis loading based on multi-rigid-body dynamics carried out before design fabrication, so as establish virtual prototype carriage; multi-body dynamic equations are obtained according Newton–Euler formula; force displacement each joint simulated by using MSC ADAMS software, results stimulation meet requirement; a full-scale (ALT) sy...
