The dynamic analysis of complex asymmetric rotor-bearing systems with finite element method
Abstract
Most dynamic analyses of rotor—bearing systems deal with symmetric rotors in the past, and the dynamic analyses of asymmetric rotors are paied much attention to now. In this paper, the rotor of any shape of cross section with irregular parts (such as rigid disks) is analysed by finite element method. The coupling effect between rigid disks is considered. The corresponding dynamic motion equations are established. The general computer program is given, and examined by a simple rotor. The results are satisfactory. As an example, the unbalance response and critical speeds of the rotor system of KRCI2X29 ring hammer crusher are calculated.
