自主研发了模拟高速高温工况专用于评价封严涂层/对偶件服役性能的刮擦式摩擦磨损试验机.通过电主轴直接驱动负载主轴的方式保证高速刮擦过程中,转动样品能够平稳的运转；采用精密进给系统使得试验过程中平动样品能够精确的向转动样品移动；通过辐照聚光加热设备可将样品加热到需要的温度,进而完成所需的高温试验；采用高频响、石英压电三向传感器能够准确的采集到试验过程中的刮擦力信息；通过自行开发的快速数据采集系统现实了对海量试验数据的准确的采集、存储和输出功能.经实车测试,该试验机的刮擦速度最高可达160 m/s,最高加热温度可达1 200℃,刮擦力的测量范围为10～1 000 N,可同时记录刮擦力、刮擦温度、扭矩和转速等所需信息.%A rubbing type of friction and wear tester was developed, which can simulate the high rubbing speed and temperature working conditions of seal coatings, especially to evaluate seal coatings/counterparts serve performance. The rotation sample can run stably through an electrical spindle directly driving the load spindle. The precision-feed system can make the translational sample move to the rotation sample accurately. The sample can be heated to the wanted temperature so that the high-temperature experiment can be carried out by using the irradiation condenser heat device. The rubbing force during the experiment can be precisely measured by a quartz piezoelectric three-sensor of high frequency response. The mass data can be fast and ac-curately collected, stored and outputted using a rapid data acquisition system. The practical test shows that the highest rubbing speed and heating temperature of the tester was 160 m/s and 1 200 t, and the arrange-ment of rubbing force was 10-1 000 N. The tester can also record the information of rubbing force, rubbing temperature, torque and rotation speed at the same time (luring the rubbing process.
