摘要
为避免出现液压油黏度过高所带来的一系列问题,提出一种液压油的黏温特性测试方法。通过在常压下测试YH-15航空液压油在-55~135℃温度范围内某些温度点的黏度,分析了YH-15航空液压油的黏温变化趋势,通过黏度与温度关系经验公式分段绘制了YH-15航空液压油的黏温特性曲线,并分段计算出YH-15航空液压油的黏温特性曲线公式。计算结果表明：随着温度的增加,YH-15航空液压油的黏度值减小,当温度高于60℃时,液压油的黏度随着温度升高减小趋势越来越平缓;当温度降低至-40℃时,液压油的黏度随着温度降低急剧增加。
In order to avoid the problems that caused by the high hydraulic oil viscosity, we put forward a test method of viscosity temperature characteristics of hydraulic oil. By testing the viscosity of YH-15 aviation hydraulic oil in the-55~135 ℃ temperature range of certain temperature under atmospheric pressure, we analyzed the viscosity temperature variation trend of YH-15 aviation hydraulic oil; Through the relationship between viscosity and temperature experience formula section, we draw a viscosity temperature characteristic curve of YH-15 aviation hydraulic oil, and calculated formula of viscosity temperature curve characteristics of YH-15 aviation hydraulic oil. The calculation results show that： with the increase of temperature, the YH-15 aviation hydraulic oil viscosity decreased; And when the temperature is higher than 60℃, the decreasing trend will be more and more gentle with the increase of the temperature; when the temperature is decreased at the value of-40℃, the hydraulic oil viscosity sharply increased with the decrease of temperature.
