Dynamic Analysis of Coupling Vehicle-Bridge System Using Finite Prism Method
Dynamic Analysis of Coupling Vehicle-Bridge System Using Finite Prism Method is a scholarly work, published in 2018 in ''International Journal of Engineering and Technology''. The main subjects of the publication include finite element method, suspension, prism, pipe coupling, structural engineering, automotive engineering, Multibody system, computer science, and bridge. To investigate the transient responses of bridges under moving vehicles, Finite Prism method was employed.In this method a combination of the finite element method representing the cross-section of the prism and Fourier series suitably chosen to represent the behavior of prism in the longitudinal direction (which satisfies the simply supported boundary conditions at the ends), is used.Explicit time integration scheme was used for solving the equation of motion for both the bridge and the vehicle.The damping was neglected in the formulation of the equation of motion of the bridge.This render was used to avoid the solution of global system of equations, because each equation becomes uncoupled with other equations.One of the main aspects in the work is the coupling of the explicit solution technique of the equation of motion with the harmonic solution, using finite prism method for the problem of moving vehicles, taking into consideration the dynamic coupling between the vehicle and the bridge.
