| 摘 要： | 为实现定位平台的大运动行程和高运动精度,建立了一种新型磁悬浮直线运动平台,该平台由磁悬浮运动装置和电磁直线驱动装置组成,具有无摩擦、高刚度等优点.针对磁悬浮直线运动平台长时间运行过程中电磁铁的发热问题,运用有限元软件对电磁铁的发热机理、发热量以及热量的时空分布进行了分析,并和实验数据进行了对比.结果表明,在常温常压下,电磁铁温度上升到一定程度后即达到平衡,不需要加装冷却装置.而在真空环境下,电磁铁温度会不断增加,必须加装冷却装置来降低温度.最后,通过仿真对真空环境下的冷却装置设计进行了简单地讨论. |

| Abstract: | A novel linear maglev transportation platform,including a levitation mechanism and a propulsion mechanism,was presented to realize long travel range and precise motion.The platform has many advantages such as friction-free and high stiffness.To analyze the influences caused by the heat generated from electromagnets,the heat generation mechanism,heat rate and heat spatial distribution were discussed with finite-element method.The analyses showed that when its work environment is NPT(normal pressure and tempe... |
