磁悬浮转子的结构设计对其工作温度的高低及分布有很大影响。研究其工作温度场与结构设计之间的关系,建立三维的磁悬浮转子温度场的数字模型,可为磁悬浮转子系统的结构设计提供可靠的依据,并且为研究温度对磁悬浮转子工作特性的影响建立进一步研究的平台。以高速磁悬浮铣削转子为实例,利用红外热像仪测量它空载旋转时温度场分布,用计算机图像处理软件,从红外热像图中获取该温度场的温度值数据,通过滤波及数据处理在二维红外热像图形基础上建立了磁悬浮转子三维温度场的数字模型。在此基础上,研究了磁悬浮转子结构设计对温度场的影响。
The structural design of the magnetic suspension rotor temperature and the distribution of its work have a great impact. To study the relationship between the working temperature field and the structural design, to establish a three-dimensional digital model of the temperature field of the magnetic suspension rotor can provide a reliable basis for the structural design of the magnetic suspension rotor system and to further study the influence of temperature on the working characteristics of the magnetic suspension rotor Research platform. Taking high speed maglev milling rotor as an example, the temperature distribution of the rotor during no-load rotation was measured by using infrared thermography. The temperature data of the temperature field were obtained from the infrared thermography using computer image processing software. Through the filtering and data processing, Based on the two-dimensional infrared thermography, a digital model of the three-dimensional temperature field of a magnetic suspension rotor is established. Based on this, the influence of magnetic suspension rotor design on temperature field is studied.
