Abstract
A vibration problem of a structure carrying moving subsystems is commonly seen in engineering applications. Most research work considers point-wise coupling between the structure and the subsystems which is adequate for traditional wheel-track vehicles, however, no longer valid for maglev trains or magnetic projectiles leveraging electromagnetic levitation. To address the issue, this paper proposes a new Timoshenko beam-moving rigid body model with distributed viscoelastic coupling, providing more accuracy and fidelity in describing the coupling between the structure and the moving subsystems. The coupled system is discretized via generalized assumed-mode method and then solved with Runge–Kutta scheme. Numerical simulations thoroughly studied the dynamic response of the beam structure and investigated the effect of system configuration on its dynamic behavior.
