实现了利用有限元结构分析软件对诸如薄壁旋转轴和转动薄壁壳体等各类形式的复杂旋转薄壁结构进行动力特性分析的目的

讨论了不同条件(单点旋转简谐激励和沿圆周呈周波型分布的激励)条件下转动薄壁壳体结构的行波振动特点.

Abstract

The dynamic response of damped gyroscopic system was researched by the complex modal method

and the concept of gyroscopic damping ratio was also put forward in this paper.With the method proposed in this paper

it is possible to analyze the dynamic characteristics of rotating thin-walled structures such as the rotating thin-walled shaft and shell.The characteristics of traveling wave vibration of shell under different load condition(single-point harmonic load and the harmonic load with k circumferential waves) were also discussed.
