Abstract

The invention discloses a microforce measurement and calibration method, based on a low temperature superconductivity microforce dynamic rotation measurement system. The complete system includes a ring-shaped superconductivity guide rail and a hard magnet rotor, and the hard magnet rotor is supported on the superconductivity guide rail. The hard magnet rotor is composed of a rotation shaft, rotorsupports and blades. The rotation shaft is evenly perforated with through holes in the circumferential direction for enabling one end of each rotor support to insert in the radial direction. The otherend of the rotor support is provided with the blade which is a rectangular net-shaped thin plate. Each blade is attached with the sustaining force which needs to be measured, and the corner of each blade is attached with a small reflection piece for performing measurement. According to the invention, the method herein makes a breakthrough by being independent from microelectronics systems in thefield of microforce measurement and accuracy thereof, can measure to-be-measured microforce in a more vivid and direct manner and display the numerical value as high as 10-9N by means the effects of the integral of a force with respect to time, can also achieves visualization in the process of measurement, and can better monitor and evaluate the test process.
