4 Overview
4.1 principle
Double centrifuge generally consists of the main centrifuge and centrifuge mounted on the main centrifuge turntable or boom, and the main
Centrifuge, parallel to the axis of rotation of the centrifuge. By controlling the main centrifuge, from the centrifuge while rotating movement,
Can reproduce the different waveforms of line acceleration, angular velocity and other physical quantities.
The working principle of double centrifuge shown in Figure 1, O1 is the center of rotation of the main centrifuge, O2 from the centrifuge rotation
Center, A from the centrifuge table and O2 distance R2 point. R1-based, rotating center from centrifuge
