ACCELEROMETER OF MAGNETIC LEVITATION WITH HIGH PRECISION

摘要

The present invention relates to a high precision magnetic levitation accelerometer for measuring the linear acceleration of the flying apparatus, comprising a magnetic shielding vacuum chamber system, a luminous interference displacement detection system, a control system magnetic and a small magnetic body serving as a test mass. With the implementation of the light interference detection technique, the accelerometer accurately measures the position and attitude of the small magnetic body in real time, and the magnetic levitation technology is applied to accurately place the small magnetic body in its position. and his attitude, so that the small body serving as a test piece is always in the center of the control system chamber.
