摘　　要：提出了车用传动装置润滑系统流动与传热的稳态仿真模型。基于一维不可压缩流动方程,建立了润滑油流动的仿真模型;研究了传动润滑系统的传热机理,采用热网络法建立了润滑系统的传热模型;对某型坦克液力机械传动装置润滑系统的流动与传热进行了仿真,预测了润滑系统的流量、压力和温度分布,仿真结果与试验值基本吻合。本研究为车用传动装置润滑系统的流动与传热性能提供了一种有效的理论分析手段和仿真方法。A steady model of flow and heat transfer in vehicle gearing lubrication system has been developed. And a lubricant flow model of vehicle gearing was established by using one-dimensional incompressible flow equations. The heat transfer mechanisms within the lubricating oil circuit were studied, and the heat transfer simulation model was developed with heat network method. An exemplary simulation has been carried out for the lubrication system of a tracked armored vehicle gearing, pressures, flow rates and temperatures in lubricating system were calculated, and the simulation results were compared to test data with good agreement. This study shows that the simulation model can be used as a theoretical analysis means for studying lubricating oil flow performance of vehicle gearings, as well as providing an useful tool.
