摘要:

开展了齿轮胶合承载能力试验,开发无线测试装置以获取齿轮本体温度数据集,并在此基础上提出了基于CatBoost的航空齿轮本体温度预测方法。此外,辨识了润滑油添加剂、热导率、扭矩、表面硬度、表面粗糙度、润滑油密度、润滑油黏度等参数对本体温度的贡献度,提出了考虑材料和油品参数的航空齿轮本体温度预测公式。结果表明,所提的公式对航空齿轮本体温度的预测误差在10%以内,为航空齿轮抗胶合设计提供了新思路。

Abstract:

The present study conducted gear scuffing tests and employed a wireless temperature measuring system to acquire bulk temperature data for aviation gears. Subsequently, a novel methodology, based upon the CatBoost algorithm, was developed with the intention of predicting the bulk temperature of aviation gears. Moreover, the contributions of parameters such as lubricant additives, thermal conductivity, torque, hardness, roughness, lubricant density, and lubricant viscosity to gear bulk temperature were identified. A predictive formula for aviation gear bulk temperature, considering materials and lubricant parameters, was proposed as a solution to the identified issues. Notably, the results demonstrate that the formulated formula achieves a prediction error within 10% for the bulk temperature of aviation gears. And the formula offers a promising method for designing aviation gears against scuffing failures.

Key words: aviation gear, scuffing failure, bulk temperature, data driven, prediction formula
