摘　　要：直升机的主动控制襟翼(ACF)型智能旋翼技术通过驱动机构带动旋翼后缘襟翼局部高频偏转,产生反相高阶气动载荷来抵消或降低旋翼高阶振动载荷,达到降低旋翼振动的目的,是直升机旋翼动力学领域发展的最新趋势之一。本文围绕使用压电材料驱动的后缘襟翼驱动机构,系统梳理了国内外各类驱动机构构型的发展历程和验证现状,对几种典型构型驱动机构的力学输出特性进行了对比分析,阐述了国内外技术差距并指出国内当前研究面临的几个主要问题,为后续国内压电驱动机构的选型、可靠性设计以及性能优化等提供参考。The Active Control Flap(ACF)type intelligent rotor technology of helicopter drives the trailing edge flap of the rotor to deflect locally at high frequency through the driving mechanism,and produces anti-phase high-order aerodynamic load to offset or reduce the high-order vibration load of the rotor,so as to reduce the vibration of the rotor,which is one of the latest trends in the field of helicopter rotor dynamics.Focusing on the trailing edge flap drive mechanism driven by piezoelectric materials,this paper systematically sorts out the development history and verification status of various drive mechanisms at home and abroad,compares and analyzes the mechanical output characteristics of several typical drive mechanisms,expounds the technical gap between China and foreign countries,and points out several main problems faced by domestic current research,so as to provide reference for the selection,reliability design and performance optimization of piezoelectric drive mechanisms in China.
