1. the content of this thesis comes from the fujian natural science found following research task 。 it studies on a space cantilever single beam attached to a moving support 。 inertia forces which are brought by the support's movement ， are acceded to the equivalent initiative forces and the equivalent initiative moments 。 when we consider the relation of the forces and deformation ， we change the method of material mechanical analysis to the elastic mechanical analysis 。 further more ， we discusses the feasibility of the method which uses the multi-rigid-body discrete model to simulate the dynamic characteristic of a elastic body 。 first ， the finite segment method is adopted to establish the models of the beam 。 based on kane's equations ， dynamic math-model for the beam are derived 。 and by use of c-language and runge-kutta procedure ， the computer-oriented procedure can give the whole responses of the beam 。 second ， with compare to the numerical examples ， the method which uses the multi-rigid-body discrete model to simulate the dynamic characteristic of a elastic body which is under the condition of movement is verified to be feasible 。
