Internal Flowpath Optimization of Wet Multi-plate Friction Clutch

The research about internal flowpath optimization of wet friction clutch has significant effect on the reduce of heat generating. Taking the diameter and position of nozzle as design parameters, the maximum and minimum lubricant pressure as constraint conditions, and the RMS of lubricant pressure applied on friction disc and dual plate as objective function, the parametric FEM optimum model of flowpath about clutch is established. Based on the method of second order response surface, the paper sets up the response surface function of objective function by structure parameter, and optimizes the objective function through quadratic programming. The optimized structure of flowpath is obtained, and the rationality of optimization result is verified.
