In order to estimate the heating value of wet multi-plate friction clutch at idle state, the heat-fluid coupling simulation of oil way fluid field is carried out. Taking oil way of clutch as research object, dynamic mesh technique is adopted to implement the dynamic simulation about fluid field in disc separation process. Based on the actual state of oil way at the end of disc separation process of disengaging clutch, simulation model about heat-fluid coupling of oil way is established through combining energy conservation law with shear heating theory of oil film. Then the paper simulates the temperature filed of lubricant, and researches the influence principle of drive shaft speed and lubricant flow on lubricant temperature. Results shows: the maximum temperature and exit temperature of lubricant increase gradually as idling speed increases; and they will decrease gradually as inlet flow increases.
