摘要
为揭示液黏传动变形界面间油膜温度场分布规律,建立油膜的三维物理模型,利用计算流体动力学原理,采用FLUENT软件对油膜温度场进行求解,并研制专门的液黏传动实验台进行实验研究。研究结果表明:平行界面和变形界面间油膜的温度随摩擦副运行时间的延长而升高,油膜温度与时间近似呈线性关系;同时,有沟槽区和无沟槽区油膜的温度沿径向递增,且有沟槽区油膜的温度远低于无沟槽区的温度;变形界面与平行界面间油膜的温度分布规律基本相同,但是,变形界面间油膜的平均温度略低于平行界面间油膜的温度。
To explore the distribution law of oil film temperature field between deformed interface in a hydro-viscous drive（HVD）,a 3-D physical model of the oil film was created.According to the principle of computational fluid dynamics,the model was solved using FLUENT software;and a special HVD test-bed was developed to verify the correctness of theoretical analysis.The research results show that the temperature of the oil film always rises during the measuring time between the parallel and deformed interfaces.The relationship between the temperature and the time is approximately linear.Meanwhile,the temperature goes up gradually along the radial direction,and the temperature of the oil film without groove is much higher than that with groove.The mean temperature between deformed interfaces is lower than that between parallel interfaces.
