【Abstract】 Based on Kane′s equations, a generalized deterministic dynamic model, valid for arbitrary structures, is introduced in this paper. In the model, the flexible bodies are described as nonlinear motion. Nonlinear terms have been retained to certain phase and linearized to form linear dynamic equations. At the same time the uncertainty characteristic of different dynamic parameters is considered. As an example, by using Monte Carlo method, the single vision based controlled flexible arm has been analyzed, and the numerical results show the effectiveness of this method.更多还原
