挠性航天器系统动力学耦合特性研究
Study on Dynamic Coupling Characteristic of Flexible Spacecraft
摘要
Abstract
Dynamic forward recursive formulation of rigid-flexible coupled multi-body system is an important modeling theory of dynamics, which will not only reduce the workload but also avoid the accumulated error. It is apt to the exact solution when applied to complex systems because it retains the influence caused by elastic vibration of flexible parts to the center of mass and moment of inertia. In this paper, the general type of forward recursive formulation to rigid-flexible coupled spacecraft system was applied, and the higher accuracy in calculation was expounded. Finally, through numerical calculation, advantage of the forward recursive method in handling the coupling of flexible system than that of the traditional method was verified.关键词
