该文考虑了带弹性帆板与液体燃料的航天器做俯仰运动时刚-液-弹之间的相互耦合作用,采用已推导的刚-液-弹耦合系统非线性动力学方程组,应用多尺度法解析分析耦合系统的液体一阶主共振,利用奇异性理论对分岔方程进行分析,得到多种分岔模式,随后根据该文研究的耦合系统物理系数范围,确定只存在滞后点分岔,表现为幅频曲线软、硬特性的转换现象。
2.
The coupled dynamics of the pitching of a spacecraft,the sloshing of liquid fuel and the vibration of elastic appendages is investigated.
考虑了带弹性帆板与液体燃料的航天器做俯仰运动时刚-液-弹之间的相互耦合作用,采用已推导的刚-液-弹耦合系统非线性动力学方程组,应用多尺度法对耦合系统液体一阶主共振的非线性动力学特性进行解析分析,发现了幅频曲线软、硬特性随液深发生转换的现象,发生转换时的临界液深值大小与液体燃料在航天器中的位置、航天器与弹性帆板的转动惯量相对于液体燃料密度的比值均有关,并通过与数值模拟比较,验证了解析分析的正确性。
