Abstract: Temperature field model for stainless steel/ copper based sintered alloy under the condition of coupled contact resistor-friction heat was established using finite element software ANSYS.The method for coupling two kinds of heat was given, the temperature field was calculated, and the maximum coupled temperatures changing with different electric currents and velocities were studied.The results show that under the constant displacement and normal force, the maximum coupled temperature increases with the increase in electric current, and decreases with the increase in velocity.
