A Study of Tip-off Problem for Dynamical Interactions between a Launched Vehicle and Its Guideway System

Abstract

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.
