Abstract: A numerical simulation method for thermalflow twoway coupling with control data exchange and mapping interpolation functions is developed for generalpurpose drum brake and is applied to the simulation of the braking on normal road with drum brake. Then the results of simulation are compared in accuracy with the temperatures measured in bench test. The results show that the thermalflow twoway coupling analysis method developed is advanced in technical means with a analysis accuracy higher than 83%, meeting engineering requirements with engineering application and dissemination values.
