航空摩擦离合器的关键技术研究

Key Techniques of Aviation Friction Clutch

航空摩擦离合器是实现直升机传动系统变转速工作的核心部件,在直升机起飞和变速换挡过程中具有重要作用。20世纪末以来,国内外学者对航空摩擦离合器的设计及特性进行了大量研究。针对航空摩擦离合器的设计,文章重点研究了摩擦离合器参数选择、接合过程温度场分析、接合过程摩擦系数分析、动力学特性分析、摩擦副磨合磨损激励以及磨损量变化规律研究等关键技术。

Aviation friction clutch is the core component to realize the variable speed operation of helicopter transmission system. It plays an important role in the process of helicopter take-off and variable speed shift. Since the end of the 20th century,scholars at home and abroad have done a lot of research on the design and characteristics of the aviation friction clutch. Aiming at the design of aviation friction clutch, in this paper, key techniques such as parameter selection of friction clutch, temperature field analysis in engagement process, friction coefficient analysis in engagement process, dynamic characteristics analysis, and change law of wear excitation and wear variation of friction pairs are presented.
