| 摘 要： | 在分析超磁致伸缩材料特性的基础上设计了一种微位移作动器.通过有限元分析,对作动器的结构进行优化,得到均匀的偏置磁场和激励磁场;设计了预压力加载结构和强制冷却结构.对该作动器的动、静态性能进行了测试,结果表明:作动器基本上工作在线性区域内,其位移伸缩量大,低频动态性能较好,高频谐波分量影响较小,相位延迟较小,同时也证明了对作动器的磁场分析和结构优化是正确的. |

| Abstract: | Considering the characteristics of giant magnetostrictive material(GMM),a micro-displacement actuator used for active vibration control was designed.By finite element analysis(FEA),the actuator structure was optimized thus to obtain the uniform offset and driving magnetic fields.The loading structure of pre-tightening force and the cooling structure were designed.Test results of static and dynamic characteristics of the actuator indicate that it nearly works in the linear range,and has large output displacement,small phase delay and low harmonic components.The design and analysis of the magnetic field and the actuator structure are verified. |
| Keywords: | actuator magnetostrictive material finite element analysis |
