摘　　要：基于ANSYS有限元软件建立钢铝复合轨/受电靴在接触电阻热和摩擦热耦合作用下的温度场模型,给出了2种热量耦合的方法,计算了模型的温度场,研究了模型在不同电流、速度和位移条件下的耦合最高温度变化。结果显示:在相同位移和法向压力条件下,耦合的最高温度随电流的增大而增大,随速度的增大而减小;在电流、速度和压力相同的条件下,耦合最高温度随位移的增大成线性增大趋势。Temperature field model for aluminum-stainless steel composite conductor raiL/collector shoe under the cou- pling of contact resistor-friction thermal was established by ANSYS finite element software. The method of coupling the two kinds of thermal was given, the temperature field was calculated, and the maximum coupled temperature changing under different electric current, velocity and displacement of the model was studied. The results show that under the constant dis- placement and normal force, the maximum coupled temperature increases with the increasing of the electric current, and de- creases with the increasing of the velocity ; under the constant elcc, tric current, velocity and normal force, the maximum coupled temperature increases linearly with the increasing of displacement.
