The Analogy Method Of The Multi-rigid-body For The Kinetic Characteristic Of A Cantilever Beam Which's Under The Condition Of Movement

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。...
