摘　　要：以压电陶瓷和柔性铰链作为驱动平台,系统地研究了面向快速车削加工的刀具伺服装置的设计、运动建模与研制方法。测试结果表明,研制的快刀伺服装置定位误差为7.7nm,重复定位误差为4.4nm,线性度优于0.145%,运动距离为39.0μm时响应频率达到了218Hz,能够满足复杂面形零件或结构的超精密快速车削加工要求,为以后该快刀系统在实际加工中更广范围的应用研究打下了基础。Based on piezoelectric actuator and flexure hinge platform, the design, morion modeling and development of FTS device were studied systematically herein. The testing results indicate that the positioning errors are less than 7.7nm, the repetitive positioning error is less than 4.4nm,the linearity precedes 0. 145% and the frequency response precedes 218Hz at 39.0μm travel range for self--developed FTS system, and these performances can completely satisfy the machining requirements for the elements or structures with complex form. A good foundation for future use was built in real manufacture.
