This paper investigated the tip-off effect problem for dynamical interactions between a launched vehicle and an elastic guideway system. The launcher guideway system is idealized as an inclined uniform simply supported elastic beam, while the vehicle is treated as a rigid beam which is forced to move along the elastic beam under the action of the prescribed thrust force. We developed a concise solution technique for the tip-off problem analysis. Equations governing interaction between the vehicle and its guideway are derived by taking account of the effects of the inertia force, Coriolis force and centrifugal force, based on the Euler-Bernoulli beam theory. Numerical results are compared with other reported literatures under several testing conditions and show excellent agreement. This study can provide valuable information on the vehicle guideway system design.

This study investigates the tip-off effect responses of an accelerated vehicle by considering the dynamic interaction between the vehicle and its guideway system. The launch system is considered as an inclined simply supported uniform elastic beam, whereas the vehicle is regarded as a rigid beam moving along the elastic beam under the action of a predetermined thrust force. A technique for tip-off effect analysis that takes into account the dynamic interactions is developed. Equations governing the interaction between the rigid beam and its guideway are derived by taking into account the influences of the inertia force, Coriolis force, and centrifugal force, on the basis of the Euler-Bernoulli beam theory. A comparison of the tip-off analysis results of the elastic and rigid guideway models indicates that the dynamic response obtained for the elastic guideway model was 20% greater than that obtained for the rigid guideway model. The simulation results of the influences of several parameters by tip-off effect analysis can provide information that is valuable when designing vehicle launch systems.
