摘要: 具有非相似余度的混合作动系统(HAS)由功率电传作动器和传统的阀控液压伺服作动器(SHA)所组成,是未来多电飞机作动系统的发展趋势。阐述混合作动系统的结构组成及工作原理,建立其数学模型。对工作于两种传统模式——主动/主动模式和主动/被动模式时的混合作动系统进行了建模和理论分析。在此基础上,论述在一种全新的工作模式——主动/无载模式下,混合作动系统的结构组成和工作原理,并对其进行建模和理论分析。最后,对混合作动系统工作于每种模式下的优缺点进行了对比分析。分析结果对确定不同情况下混合作动系统的具体工作模式提供了依据。

Abstract: Hybrid actuation system (HAS) with dissimilar redundancies conforms to the development trend of future actuation systems in more electric aircraft. It is composed of a power-by-wire actuator and a traditional servo valve controlled hydraulic actuator (SHA). The structure and operating principle of HAS are represented, and its mathematic model is established. Modeling and theoretical analysis for the HAS operating in conventional operating modes, i.e., the active/active mode and active/passive mode, are carried out. Furthermore, a new operating mode of HAS, the active/no-load mode, is proposed. The structure, operating principle and modeling of HAS in this new mode are respectively discussed. Finally, comparative analysis is performed when HAS operates in these three modes. The analysis results provide a guideline to determine the specific operating mode of the HAS in different circumstances.
