5.5 Measurement system with more functions and higher precision Ë 131Fig. 5.14:Researchers are testing and calibrating accuracy of SCML-02 measurement system.
- Maglev measurements between the HTS bulk specimens and a cylindrical PM or
a PMG. - Simultaneous measurements of the levitation forces and guidance forces for
which the sample can be displaced vertically and horizontally at the same time. - Synchronous measurements of not just the levitation and guidance forces, but
also the cross stiffness of the levitation forces or the guidance forces in a real-time
independent measurement along the vertical or horizontal. - Interaction of dynamic rigidity of levitation forces and guidance forces synchro-
nous measurements. - Relaxation time of levitation forces and guidance forces measurements along the
vertical or horizontal directions.
The SCML-02 Maglev measurement system’s main technical specifications are as
follows:
- Vertical maximal displacement of 150 mm.
- Horizontal maximal displacement of 100 mm.
- Position precision of 0.05 mm.
- Vertical maximal support force of 1000 N.
- Vertical force precision of 2.
- Horizontal maximal support force of 500 N.
- Horizontal force precision of 1.
5.5.3Measurement precision calibration
In order to calibrate the measurement precision of the SCML-02 HTS Maglev measu-
rement system, two cylindrical PMs were used. The two PMs have the same strength
