Abstract:
When multidisk 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 welldistributed in design. With the use of ANSYS/FLOTRAN software, 3D 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.
