초록
Transmission fluid film behaviors in the gap between the wet clutch pad and separator plate are analyzedusing the CFD software ADINA. Three pattern groove designs are selected and are used to validate thefluid film behaviors based on the outlet flow in the gap when the wet clutch pad and separator plate are engaged. The main design goal for pattern grooves is faster engagement. In most cases, much of the outlet flow of transmissionfluid in the gap occurs on the outer radius boundary due to the centrifugal force generated by the clutchpad circular motion. Groove patterns are created to ensure faster transmission fluid outlet flow in the directionof the inner radius boundary. Computational results of the selected groove patterns are compared.
