Abstract:When a vehicle runs on a bridge, the vehicle and the bridge will be mutually influenced in the dynamic behavior, which is called vehicle-bridge interactions. The vehicle-bridge coupled vibration theory can provide the theoretical basis, analysis method and assessment technique for bridge design, line operation, maintenance and management, and it is of important engineering application value. Many scholars have carried out a lot of relevant researches since the 20th century. At present, China's transportation industry has developed rapidly. Conventional vehicle-bridge interaction dynamics are challenged by the dense transportation network, tight transportation capacity, complicated line conditions, etc. Thus, the related theory and technique are being and further developed. This paper summarizes the progress and advances of the vehicle-bridge interaction field in 2019, including the vehicle-bridge interaction model under track irregularity, vehicle-bridge random vibrations under track irregularity, wind-vehicle-bridge coupled vibrations, earthquake-vehicle-bridge coupled vibrations, and maglev vehicle-bridge coupled vibrations. Furthermore, the research hotspots and prospects are provided. The work is expected to promote more comprehensive and in-depth basis researches.
