摘要
针对高超声速飞行器的结构/控制耦合问题,分析了结构/控制耦合效应关系。通过有限元分析方法对高超声速飞行器结构进行静力计算,结合计算结果,从结构弹性变形及弹性振动两方面出发,分析研究结构刚度特性对控制制导特性产生的影响,并对影响因素和耦合效应进行定量或定性的分析及评估,为高超声速飞行器的结构设计以及控制制导系统的设计提供参考。
This paper focuses on analysis of the structure/control coupling of hypersonic vehicle, and ap- plies FEM to the analysis and calculation of hypersonic vehicle structural characteristics. Analyze and study the impact of structural stiffness characteristics on control guidance characteristics based on the re- sult of FEM, and then make qualitative analysis and quantitative calculation of the influencing factor and coupling effects to provide a reference for the structural design of hypersonic vehicle and control system design.
