公路车-桥耦合振动的理论和应用研究进展

In order to promote the theoretical development of vehicle-bridge interaction (VBI) and application of VBI simulation techniques, this review systematically summarizes the state of the art, remaining gaps, and predicted trends in the research field of VBI in terms of both theory and application. From a theoretical perspective, numerical models for vehicles, bridges, and road surface roughness, as well as numerical methods for solving the time-variant dynamical system of VBI, were thoroughly examined. Following a comprehensive review, it was found that these numerical models are able to achieve increasingly realistic simulations of VBI. For future theoretical research, it is advised that finite element modeling techniques and optimized numerical methods should be improved upon to further increase the accuracy and efficiency of VBI simulation. From an application perspective, six applications of VBI (dynamic impact factor, fatigue of highway bridges, damage detection, vibration control, ease of driving on bridges, and vehicle weight identification) are discussed to highlight the uses of VBI in research fields relating to bridge safety and serviceability. The remaining gaps in these research areas are also identified and corresponding future research is proposed. The current research demonstrates that VBI simulation has become an important tool in many relevant research fields, while its applications also show promising prospects in other related fields. For future research, the suitability and accuracy of VBI models need to be adjusted for the specific issues targeted, relevant theories need to be further developed for targeted research, and existing technologies need to be improved from the perspective of engineering practice.
