AI Technical Summary
Technical Problem
Existing gas turbine compressor blades are prone to loosening between themselves and the mounting base during operation, leading to potential safety hazards.
Method used
Anti-vibration grooves and blade root grooves are set at the tail of the blade body to form an anti-vibration space, within which flexible vibration damping components are installed. The height of the flexible vibration damping components is not less than that of the anti-vibration space, thereby enhancing the blade's vibration resistance.
Benefits of technology
It effectively reduces the safety risks caused by blade vibration, prevents relative movement between the blade and the mounting base, and improves the stability of blade installation.

Abstract
本发明涉及燃气轮机压气机配件技术领域，具体涉及一种燃气轮机压气机叶片安装结构及燃气轮机压气机。燃气轮机压气机叶片安装结构，包括：叶片本体，其叶根本体的尾部设置有抗振槽；安装件，其上设置有叶根槽，叶根本体与叶根槽卡紧配合，叶根槽底部设置有配合槽，配合槽与抗振槽对齐设置，配合槽与抗振槽围合成抗振空间；柔性减振件，安装在抗振空间内，柔性减振件的高度不小于抗振空间的高度。在叶片本体工作产生振动时，柔性减振件能够在横向和纵向两个方向削减叶片本体转动时的振动能量，能够有效防止叶片本体的叶根本体在持续的频繁振动下与安装件之间发生相对移动。能够有效降低叶片本体振动导致的叶片本体安装不稳定带来的安全风险。
