Abstract
An analytical method for the vibration analysis of unidirectional and multi-branched torsional systems is investigated. In the study, an alternative power-flow graph model and the model operation technology are introduced for constructing the analytical graph model of the torsional system, including internal and external damping properties. Then, the formula for the frequency response of each component can be derived directly according to the power-flow graph model of the system and the topology synthesis. Based on the method developed, the rotation response at the end of each shaft as well as the internal rotation and internal torque response of the system can be efficiently calculated by computer due to the summation expression in the derived formula. Since the derived formula is expressed in operation, it is very effective to calculate by computer. Finally, some different types of torsional systems are investigated in the examples to illustrate the effectiveness of this method on the vibration analysis of complex torsional systems. © 1999 Academic Press.
