摘要：

研究用新型功能材料——磁流变液制作阻尼固紧器，具有减小电机振动和实现微冲击固紧工作台的双重功能. 通过有限元分析对其磁路进行了仿真，并用往复运动实验系统对其性能进行了标定. 在纳米三坐标测量机上进行的纳米定位实验表明，加上磁流变阻尼固紧器后，工作台定位稳态波动从20 nm减小到5 nm以内，可实现纳米三坐标测量机纳米级定位稳态波动.

Abstract:

A locking damper based on the new functional materials, magnetorheological fluids, is studied. It can reduce vibration of driving motor and make a micro-impact locking for the working table. The magnetic circuit is simulated with finite element analysis and the property is calibrated using a reciprocating experimental system. It is used in Nano-CMM for nano-positioning experiments, showing that positioning steady-state fluctuation of the working table is reduced from 20 nm to less than 5 nm when the MRF locking damper is used. It ensures the nano-degree positioning steady-state fluctuation in Nano-CMM.

Key words: magnetorheological fluids, MRF locking damper, micro-impact locking, positioning, Nano-CMM
