湿式离合器温度场仿真分析及沟槽结构优化研究OA
Study on Temperature Field Simulation and Groove Structure Optimization of Wet Clutches
为研究沟槽对湿式离合器冷却性能的影响,基于k-ε两层湍流模型和欧拉方法Volume of fluent model(VOF)模型,采用STAR-CCM+软件建立湿式离合器仿真模型.在不改变沟槽流动横截面积的前提下,对沟槽形状进行优化,再通过STAR-CCM+进行仿真分析,得到了径向沟槽内流场和温度分布情况.结果表明:在相同沟槽流动横截面积和相同冷却液流量的情况下,优化后的沟槽结构冷却效果得到明显提升.在此基础上,对沟槽结构进行深入研究,得到了不同流量和转速差下的冷却效果,为湿式离合器摩擦片的设计及优化提供理论参考.
To study the effect of grooves on the cooling performance of wet clutches,a simulation model of wet clutches was established,with use of STAR-CCM+software.The model is based on the k-e two-layer turbulence model and the euler volume of fluent model(VOF)model.Without changing the cross-sectional area of the groove flow,the shape of the groove was optimized,and simulation analysis was conducted using STAR-CCM+to obtain the flow field and temperature distribution in the radial groove.The results show that under the same cross-sectional area of the groove flow and the same coolant flow rate,the cooling effect of the optimized groove structure is significantly improved.On this basis,in-depth research was conducted on the groove structure to obtain the cooling effect under different flow rates and rotation-speed differences,providing potential theoretical evidences for the design and optimization of wet clutch friction plates.
