摘　　要：输电装置可实现从固定部件到旋转部件的信号和功率传输。通过ANSYS有限元分析软件模拟分析了输电装置在给定压力、约束和相同的转动圈数下,因不同合金材料热膨胀系数区别导致的摩擦副接触特性的变化情况,并与Bruker高精度三维光学轮廓仪下检测的导电杆试验件接触区坐标偏移量及磨损程度进行比较。试验结果表明,理论模型可有效揭示在使用温度变化时,刷环接触区的位置和应力变化,并根据试验结果针对性地采取工艺措施,进而提高输电装置在不同使用温度中的接触可靠性。The slip-ring can realize signal and power transmission from fixed parts to rotating parts.It has been simulated and analyzed the change of the contact characteristics of the friction pair caused by the difference of the thermal expansion coefficient of different alloy materials under the given pressure,constraint and the same number of rotations through the ANSYS finite element analysis software in this paper,which has been compared with the contact area coordinate offset and wear degree detected by Bruker high-precision three-dimensional optical profiler.The results show that the theoretical model can effectively reveal the position and stress changes of the friction pair contact area when the working temperature changes.And according to the test results,some technical measures can be taken to improve the contact reliability of the transmission device in different working temperature.
