摘　　要：通过对直升机滑油系统及部件工作原理研究的基础上,建立了温度、压力、流量多因素耦合稳态仿真模型,并用Visual C++6.0编制了相应计算软件。利用仿真计算结果对滑油系统及其主要部件的阻力性能进行了分析,确定了影响系统阻力特性的主要部件和主要影响因素,分别为滑油泵、过滤器、散热器、喷嘴和滑油温度、飞行高度。在对系统流量、阻力特性研究的基础上对系统高空性能进行了预测,为部件选型及系统管路的优化设计提供了参考依据。Based on the research of working principle of the helicopter oil cooling system and its main components, a steady-state simulation model of multi- factor coupling is established, including temperature, pres- sure and flow. A simulation software is developed with VC＋＋ 6.0. Utilizing the simulation software and the cal- culation results, resistance characteristics of the oil system and key parameters are analyzed in order to determine the main components and main factors that impact the resis- tance characteristics of oil system, which are lubricating oil pump, filter, radiator, nozzle and oil temperature, flight altitude respectively. On the basis of analysis, system resis- tance characteristics under different flight conditions and altitudes are predicted, which also provide a reference for the components selection and the optimal design of the oil system.
