The temperature field model of pin-on-ring friction pair was established by FE software ANSYS under the coupling effect of electromagnetic induction heat and friction heat. The coupled temperature field distribution and variation rule of the friction pair were simulated and analyzed under different electromagnetic induction frequency and velocity. The results show that when the rotation angle, stress and electromagnetic induction frequency are constant, the maximum coupled temperature is increased linearly, and the area of pin temperature gradients is narrowed with the increasing of velocity ; the maximum coupled temperature rises with the increasing of electromagnetic induction frequency under the constant rotation angle, stress and velocity.运用ANSYS对销一环摩擦副建立耦合温度场模型，模拟和分析摩擦副在不同的电磁感应频率和线速度条件下的感应热与摩擦热耦合温度分布及变化规律。结果表明：在相同的转动角度、应力和电磁感应频率条件下，耦合的最高温度随线速度的增大而成线性增大，销的温度梯度分布面积随着速度的增大而减小；在相同的转动角度、应力、线速度条件下，耦合的最高温度随感应频率的升高而增大。
