Abstract:

Interval dynamic response analysis of vehicle-bridge interaction system with uncertain parameters is studied in this paper. By introducing the interval algorithm into the dynamic analysis of vehicle-bride interaction system, the expressions of the midpoint value, interval width, lower and upper bounds of interval bridge dynamic response are developed. A heuristic optimization method, a novel particle swarm optimization method with low-discrepancy sequence initialized particles and high-order nonlinear time-varying inertia weight and constant acceleration coefficients (LHNPSO), is then developed to find the bounds of bridge displacement. Examples are used to illustrate the effectiveness of the presented methods and Monte-Carlo simulations are implemented to validate the computational results. The effects of individual system parameters on bridge response are also investigated. © 2013 Taylor & Francis Group.
