针对翼吊式发动机机翼系统的特点,运用Hamilton原理建立了计及发动机陀螺效应的Bernoulli-Euler悬臂梁振动方程;从陀螺力矩理论出发,分析了转子对结构的耦合作用机理,研究了不同转子转速和结构参数条件下,转子陀螺效应对悬臂梁结构固有特性的影响,从而为进一步研究计及转子陀螺效应的大型客机机翼发动机系统动力学特性及气动弹性特性奠定了一定的理论基础。
According to the characteristics of the wing system of wing-mounted engine, the vibration equation of Bernoulli-Euler cantilever beam considering the gyroscopic effect of the engine is established by using the Hamilton principle. Based on the theory of gyroscopic moment, the coupling mechanism between the rotor and the structure is analyzed. Speed and structural parameters of the gyroscopic effect of the rotor on the inherent characteristics of the cantilever beam structure, which will provide a theoretical basis for further study on the dynamic characteristics and aeroelastic characteristics of the large passenger aircraft wing engine system considering the rotor gyro effect.
