Abstract

The gyroscope is a kind of device for inertial navigation, it is driven by maglev rotor in the high-speed movement of liquid. However, the friction heat was produced, especially this kind of heat has a great influence on the bonding force of the gyroscope. In this study, Aluminium and 2J85 are two kinds of material for rotor. The rotor d of nanoperformance is best: its best parameter was that gyroscope can twirl in 5500 rad min−1, and its nanostructure was measured using the white light interferometer. Its parameters were for: 264·059 nm; 1·363 µm; 728·338 µm; 1·019 µm; handle: 1·312 µm. Thus, in this study, the rotor d was selected as the best nanosurface structure. This kind of materials was selected for the rotor when the gyroscope was in high speed of rotation, and it can meet the accuracy of measurement.
