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

A system of structural dynamical equations of the Bernoulli-Euler cantilever beam with gyro effects was established, using the Hamilton Variant Principle, to simulate the wing-mounted engine/wing system. The me-chanism of coupling effects of the rotor to the structure was analyzed based on the basic theory of gyroscopic mo-ment. The effects of the rotor to the structural dynamical characteristics, with different rotational speeds and struc-tural parameters, were analyzed. This research provided a theoretical foundation for the further study of character-istics of the real wing-engine system, as well as its aeroelastic performance.
