NECESSARY CONDITIONS OF STABILITY MOVING PARTS OF ROTOR CENTRIFUGE
Keywords:Motion, stability, rotation, speed, vibration
AbstractDesign features of modern centrifuges studied. Revealed that their rotors are movable elements that revolve around horizontal axes. The dynamics of these moving parts of laboratory centrifuge considered. Using the Lagrange equation of the second kind the resulting differential equations of their motion considered. The modeling visualization of motion using the software package RecurDyn was made. The results that obtained by the research package RecurDyn and analytically showed that their motion can be unstable in the positions that are optimal in terms of the technological process. The differential equation can be not integrated in elementary functions, so direct analysis of movement is difficult. As a result of this stability conditions for motion with linear approximation investigated. Necessary conditions for stability of motion required of the design obtained.
