| Abstract: | Techniques of automatic modeling for dynamic analysis of flexible multibody system of guns are introduced in this paper. With these techniques, identification of systems configuration, determination of coordinate frames and degrees of freedom, application of load, generation and solution of motion equations can be processed automatically. Thus, the dynamic simulation for launching of any guns can be carried out easily, offering useful guidelines on design of guns. |
