Abstract:
The modeling of the rotor-support system of a typical centrifuge
is discussed. The impedance matching method, cooperating with
Riccati transfer matrix method and modal analysis method are
adopted to calculate its dynamic characteristics. The influences
of the main parts to the critical speeds are analyzed. Based on
the analysis, a critical speed in the operating speed range is
tuned successfully, and thus the dynamic characteristics of the
centrifuge are much improved.
Key words: Centrifuge Dynamic characteristics Impedance matching method
