| Abstract: | From the view of engineering practice, this paper concerns the multibody system dynamics in launch vehicle, emphasizes its importance and points out some development directions in this field.,providing some reference to the engineering of launch vehicle,such as tank shaking, separation devices and joint mechanism. It is proposed to combince the characteristics of the launch vehicle's overload and multi-phase coupling to carry out high-order, strong nonlinear dynamics research and engineering software development. |
