摘　　要：附件机匣齿轮传动系统作为航空发动机附件动力传递与驱动的关键基础部件,其传动构型与结构设计繁琐,且涉及元件和系统的设计参数众多,传统基于经验公式与零散程序的设计模式难以满足先进航空装备对高承载、长寿命、轻量化传动系统高效设计要求。为此建立了“构型设计—元件设计—系统分析—系统优化”的航空发动机齿轮传动设计方法,基于C++/Python程序语言开发了航空发动机附件机匣齿轮传动设计分析软件。同时依据设计需求,应用所开发软件生成了四种传动构型方案,优选同轴多输出非对称分流构型,以轻量化、高承载为优化目标,基于NSGA-Ⅱ算法开发传动系统多目标优化模型,实现齿轮组减重15.81%,薄弱环节齿轮传动安全性提高2.98%,为新一代航空高端装备齿轮传动设计提供了理论方法和软件工具。The accessory gearbox gear transmissions were pivotal components for power transmission of the aero-engine accessories.The configuration and structure design of the accessory gearbox transmissions for aero-engines were complex,involving many parameters of components and system.Traditional design methods based on empirical formulas and scattered software programs could not meet the more efficient design requirements of advanced aviation equipment for high load capacity,long service life,lightweight,high performance transmission systems.Therefore,a“configuration design—component design—system analysis—system optimization”method for aero-engine gear transmission design was established,and the aero-engine accessory gearbox gear transmission design and analysis softwares were developed based on the C++/Python.According to the design requirements,four configuration schemes were generated applying the software,and a coaxial multiple-output non-symmetric power split configuration scheme was selected by comparison.A multi-objective optimization model for the transmission system was developed based on the NSGA-Ⅱalgorithm.With lightweight and high load capacity as the optimization goals,a reduction of 15.81%in gear transmission weight and an improvement of 2.98%in weak gear transmission safety are achieved.This provides theoretical methods and software tools to the research of gear transmissions for new generations of advanced aviation equipment.
