摘要
本文用假定模态法把原混合动力系统离散成多自由度系统。由R0uth方程推出非循环坐标系统方程,根据稳定性定理推出系统稳定性判据。由此分析了挠性帆板和内部转子对稳定性的影响。
The original hybrid dynamic system is changed into the discrete system with multi- pie freedoms using the hypothesis models in this paper. The linearized dynamic equation of the noncirculation corrdinates can be derived from Routh equation. Also, the system stability criterion is deduced in accordance with the stability theorem thereby to analyze the effects of flexible arrays and momentum rotors on the system stability
