本文计算分析了整圈松拉金叶片组异相振动沿叶高方向的振型特性以及整圈连接后由于共振振型与自由叶片不同而引起的应力水平的变化,对于扭曲叶片给出了计算实例,对于直叶片的切向振动讨论了一些性质规律。主要结论如下:(1)整圈叶片组异相振动振型特性以及相对应力分布等随拉金和叶 In this paper, we calculated and analyzed the modal characteristics of out-of-plane vibration of slack gold leaf in the whole circle along the leaf height and the stress levels caused by different resonance modes and free blades after the full circle connection. Some examples discuss the nature of the tangential vibration of straight blades. The main conclusions are as follows: (1) The characteristics of out-of-phase vibration modes and the relative stress distributions of the entire blade group with the pull of gold and leaf
