摘要
为优化超磁致伸缩激振器的工作特性,对激振器的磁路结构进行研究和设计,得到了相应的结构参数。结合麦克斯韦电磁学理论建立激振器磁路的有限元模型与动态数学模型,分析导磁体和等效质量对激振器磁路结构和输出特性的影响,得出该激振器相应的设计方案。应用数据分析表明,用此激振器搭建的振动时效平台能够满足时效工件对激振源的要求。
To optimize the output performance of giant magnetostrictive vibrator,the magnetic circuit structure of magnetic circuit was designed and studied. The corresponding structural parameters were obtained. Based on Maxwell electromagnetic theory,the finite element model and mathematical model of the vibrator were established,and the effects of the magnetic flux and the equivalent mass on the magnetic circuit structure and the output characteristics were analyzed. Finally,the design scheme of the vibration vibrator was presented. The application of the data analysis shows that the vibration stress relief platform can satisfy the requirement of the vibration stress relief.
