【摘要】 以稀土超磁致伸缩材料作为驱动元件的电-机转换技术具有传统技术无法比拟的性能优势。利用这种新技术的器件在设计方面有一些特定的原则。国外用稀土超磁致伸缩材料已研制了声纳和超声换能器,精密定位、马达、泵、阀、燃料注入、主动减震和制动等方面的致动器及传感器等器件,用于有关海洋、地质、航空航天、运输、加工制造、医学、计算机、机器人、仪器、电子及民品等技术领域。国外稀土超磁致伸缩材料市场正迅速发展。更多还原

【Abstract】 Against traditional electro-mechanical conversion techniques,that based on rare earth giant magnetostrictive materials(RE-GMSM) possesses incomparably superiorities.Some principles in designing devices using RE-GMSM were discussed.Using RE-GMSM,many new devices have been developed abroad, for example sonar and ultrasonic transducers,micropositioner,liner and rotary motors,servo pumps and valves,fuel injection systems,anti-noise and vibration control systems,brakes by wire,sensors,surface acoustic wave devices and thin film elements etc.They were extensively applyed into the fields about ocean,geology, aerospace,defence,transportation,processing and manufacturing,medicine,computers,roborts,instruments, electronic elements and civil products.The RE-GMSM markets are growing rapidly abroad.更多还原
