摘　　要：振荡热管砂轮在航空难加工材料的磨削加工中可以显著降低磨削温度,防止磨削烧伤。为了更好地指导振荡热管砂轮设计,需探究振荡热管在不同旋转条件下的传热性能,文中设计了全新的旋转振荡热管传热性能试验平台。通过磁耦合谐振无线供电的方式为振荡热管的加热元件供电,实现振荡热管模拟磨削热载荷的加载;通过微控制器采集温度信息,并以无线通信的方式传输温度数据,以克服现有的基于电刷滑环的试验装置在高转速下存在的信号干扰和机械磨损等问题;通过试验确定了无线供电装置的最佳工作参数,测定了信号采集系统的测量误差,并通过旋转振荡热管的传热性能试验验证了测试平台的性能。The oscillating heat pipe's grinding wheels can significantly reduce the grinding temperature and prevent the grinding burn in the grinding process of hard-to-machine materials in terms of aviation.In order to better support the design of the oscillating heat pipe's grinding wheels,efforts should be made to explore the oscillating heat pipe's heat-transfer performance un-der different rotary conditions.In this article,a new test platform is designed for the rotary oscillating heat pipe's heat-transfer performance,the heating elements are powered by the wireless power-supply device characterized by magnetic coupling reso-nance;as a result,the simulated grinding heat is loaded.Besides,the information on the temperature is acquired by the micro-controller,and the temperature signal is transmitted by wireless communication,in order to overcome signal interference and me-chanical wear of the current high-speed test device based on the electrical brush and slip ring.Some tests are conducted to identi-fy the optimal operating parameters of the wireless power-supply device and work out the error of the signal-acquisition system.The test platform's performance is examined through the test on the rotary oscillating heat pipe's heat-transfer performance.
