摘要
主减速器散热系统是直升机主减速器的重要组成部分,其功能是对直升机主减速器在各种工况下的滑油温度进行调节,使其在最适宜的滑油温度下工作。建立温控阀、散热器、主减速器等部件的参数模型,在此基础上搭建主减速器散热系统仿真计算模型,研究温控阀对主减速器散热系统滑油温度的控制规律。研究结果表明温控阀能够提升主减速器冷起动过程的温升速度并提高低温环境下的滑油温度,也表明低温环境下的主减速器滑油箱滑油温度与温控阀的开启温度相关。
The cooling system is an important part of the helicopter main gearbox.Its function is to adjust the temperature of the main gearbox of the helicopter under various working conditions,in order to make main gearbox work in the most appropriate environmental temperature.On the basis of parameter model of thermostat,radiator,main gearbox and other components,the simulation model of main gearbox cooling system was established.Thethermostat for the oil temperature control law of the main gearbox cooling system was studied.The investigation results indicated that the thermostat could increase the temperature rise speed of the main gearbox during the cold start process,and increase oil temperature in low temperature environment,also indicated that the oil temperature of the main gearbox oil tank was related to the opening temperature of the thermostat.
