Abstract
Disclosed is a method for optimizing feature parameters of straight grooves of a wet friction element and relates to the technical field of heavy-duty vehicle transmission. By using the method, the feature parameters of the straight grooves of the wet friction element can be improved by optimization, and the thermoelastic stability of the wet friction element can be improved.
