ABSTRACT:Objective To study the effect of the torsional stiffness of shaft coupling on the speed stability of centrifuge systems. Methods Using the MATLAB/Simulink simulation software as a tool, the simulation model of the centrifuge speed servo control system containing the module of shaft coupling's torsional stiffness and damping characteristics was built, and the effect of the torsional stiffness of shaft coupling on the speed stability of centrifuge systems was analyzed. Results It was shown that:selection of shaft coupling with higher torsional stiffness could help the centrifuge systems to promote the capability against the external disturbance torque, while selection of shaft coupling with lower torsional stiffness could reduce the impact caused by the inherent disturbance torque in the servo-drive system. Conclusion The selection of torsional stiffness of the shaft coupling should be decided by the disturbance torque composition of the centrifuge.
