摘要
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 mechanical structure of a magnetic suspended rotor had great influence on its temperature and to the study of distribution of temperature field. Temperature field measurement had significance the mechanism of temperature raise of a magnetic suspended rotor. The measuring and processing process of the temperature field of the high-speed magnetic suspended rotor was presented. The image and data processing method was introduced. During the above work, a new data processing method ＂particular spots filter＂ was put forward. The establishment of three dimension （3D） digital model of a magnetic suspended rotor provided a method to study the relation between temperature raise and mechanical structure,and a powerful research platform for further research of a magnetic suspended rotor.
