摘要
对于稀土超磁致伸缩材料设计的传感和驱动一体化装置,由于运行的工作条件所致,传感材料会受到温度的影响。主要对装置的设计进行优化,采用强制水冷装置,分别设置单水冷腔和双水冷腔来减少温升这一因素对装置的影响,来优化装置的性能。并且通过有限元模拟来分析水冷装置对于GMA内部温度分布的影响来评估水冷装置的作用。从温度云图可以发现,单水冷腔相较于没有设置冷却结构的装置来说温度明显下降,而双水冷腔的温度相较于单水冷腔来说又进一步下降,说明这种优化结构具有很大的应用潜力。
The magnetostrictive actuators baseed on giant magnetostrictive material has its temperature problem due to working conditions. In this paper, the design of the device is optimized, and the effects of temperature on the devices is reduced by using two different forced water cooling devices to optimize the performance of the device. And the effect of water cooling device is evaluated by finite element method to simulate the influence of water cooling device on the temperature distribution inside GMA. Through software simulation, we can evaluate the temperature of the three devices adopted in this paper. Compared with the one without water cooling device, the one set up with single water cooling cavity's temperature has decreased a lot. And the one with double water cooling cavity's temperature has decreased even more, which indicates the construction in this essay has its potential in use.
