中文摘要：
湿式多片摩擦离合器空转时,为了避免由于摩擦片与对偶片分离不彻底产生的滑摩现象,减少离合器发热,在离合器润滑油流道设计时应尽可能保证摩擦片间的油压均匀分布。应用ANSYS/FLOTRAN软件,建立6种不同离合器润滑油流道结构的三维有限元分析模型;基于计算流体动力学理论,采用有限元法进行流场分析,得出各种流道结构对摩擦片间润滑油压分布的影响规律。结果表明,右端4个喷油孔贯通的结构好于不贯通结构,喷油孔形状采用锥形或阶梯形时好于柱孔,通过改进油流路径和喷油孔形状均能使摩擦片间润滑油压力分布均匀。
英文摘要：
When multi-disk clutch is in disengaged operation,friction plates and mating plates may not separate absolutely.To avoid the slipping friction caused by this and reduce the clutch＇s overheating,the lubricant pressure between the plates should be well-distributed in design.With the use of ANSYS/FLOTRAN software,3-D finite element models of six different channel flow structures are established.Using finite element method and the fluid dynamic theory,the flow field is analyzed,and then the law of the influence of different channel flow structures on oil pressure distribution between the plates is summarized.The result of the study shows that the four squirt holes at right side with perforated structure are better than those without,and squirt holes with the cone or stepped shape are better than those with column shape,which means that with the two improvements of the channel flow structure,the lubricant pressure distribution can be uniformed.
