This paper proposes a time-integration analysis scheme for the vehicle-bridge-interaction problem. Key feature is the introduction of artificial auxiliary contact points between the wheels and the bridge deck elements in contact. The artificial points allow the formulation of two sets of kinematic constraints and two sets of contact forces (i.e. localized Lagrange multipliers), between the vehicle...
This paper examines the dynamic response of vehicle(s) moving at high speeds and the sustaining horizontally curved (simple, continuous or multi-unit) bridges, when each subsystem is set into resonance. The bridge is simulated by finite elements and each vehicle as a multibody system. The coupling contact forces, between the vehicle and the bridge, are derived by adopting a rigid contact assumption...
