摘要/Abstract

摘要： 针对航空传动“降本减重”的需求，开展航空发动机“以塑代钢”齿轮传动高功率密度设计方法研究。通过高温喷油润滑条件下塑料齿轮承载能力试验，获取了不同温度和可靠性下塑料齿轮承载基础数据，修正了塑料齿轮承载能力计算方法，为航空齿轮“以塑代钢”提供了准确的强度边界。进而，构建了基于自适应遗传优化算法－CatBoost代理－系统综合服役性能评估的航空传动系统优化模型，通过传动系统中材料、结构、性能参数协同设计，实现在满足强度、结构、振动等约束下，某发动机附件机匣传动系统功率密度从9.8 kW/kg提升到19.6 kW/kg，为动力传递场合塑料齿轮系统设计提供了参考。

Abstract: A high-power-density design method for aeroengine gear systems by replacing steel with plastic is investigated to address the demands for cost and weight reduction. Durability data for plastic gears under varying temperatures and reliability conditions were collected, through experiments involving oil spray lubrication and elevated oil temperatures, defining accurate strength limits for the conversion from steel to plastic. An optimization model for aeroengine gear systems was developed using an adaptive genetic optimization algorithm, CatBoost surrogate sub-models, and system comprehensive assessment indicators, which improve the power density of a gear transmission in a gas turbine engine from 9.8 kW/kg to 19.6 kW/kg, in coordination with material, geometry, and performance parameters subject to strength, vibration, and structural constraints. This method offers an effective approach for substituting steel with plastics in power transmission systems.

Key words: plastic gears, aeroengine gear systems, high-power-density design, durability data
