| 摘 要： | 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。

| Abstract: | Structural dynamic equations of a Bernoulli-Euler cantilevered beam with gyro effects were established using Hamilton principle to simulate a wing-mounted engine-wing system.The mechanism of coupling effects of rotor and structure was analyzed based on the basic theory of gyroscopic moment.The impacts of the rotor gyroscopic effect on the structural dynamic characteristics under different rotating speeds and structural parameters were analyzed.The results provided a theoretical foundation for the further study on the characteristics of a real wing-engine system and its aeroelastic performance. |

| Keywords: | bending-torsion coupling beam vibration gyroscopic effect gyro-elastic system |
