Abstract

The control and separation of a scanning device moving along an arbitrary trajectory on an elastic plate is investigated. The system is a moving mass problem and is difficult to analyze directly. A semi-analytical method for the movingmass model is presented here. Without vibration control, the separation of a vehicle from a plate is likely to happen. The mechanism of separation of a vehicle from a plate is studied. Moreover, the effects of several parameters on vibration separation and the critical speed of system are studied. An effective control methodology is proposed for suppressing vibration and separation This model is applied to simulate a system containing a device scanning a plate. Due to the complexity of the moving-mass model, it is usually approximated by the moving-load model in most literature. The analytical solution of the moving-load model is also derived here and compared to the proposed models.
