Method for evaluating heat dissipation capability of wet friction plate oil groove

The invention discloses a method for evaluating the heat dissipation capability of an oil groove of a wet friction plate. The method comprises the following steps: step 1, determining oil groove simulation schemes of m friction plates; 2, friction plate oil groove flow field analysis models corresponding to the m oil groove simulation schemes are constructed in flow field analysis software; 3, by changing the heat dissipation rotating speed and the cooling flow, the heat dissipation power and the oil film shearing moment of the inner surface of the friction plate containing the oil groove in the surface of the friction plate under the n typical heat dissipation rotating speeds and the p typical cooling flow in the m oil groove simulation schemes are obtained, and the heat dissipation coefficient of the friction plate oil groove in the ith oil groove simulation scheme is calculated; 4, comparing the oil groove heat dissipation coefficients calculated by m oil groove simulation schemes, wherein the oil groove s
