✦ Synopsis

An analytical method for the vibration analysis of unidirectional and multibranched torsional systems is investigated. In the study, an alternative power-Β―ow 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-Β―ow 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 eciently calculated by computer due to the summation expression in the derived formula. Since the derived formula is expressed in operation, it is very eective to calculate by computer. Finally, some dierent types of torsional systems are investigated in the examples to illustrate the eectiveness of this method on the vibration analysis of complex torsional systems.

The purpose of this paper is to present a simple approach for eliminating the &&dependent'' torsional angles existing in the reduction gears of a gear-branched system so that this system may be modelled as an equivalent straight-geared (or direct-transmitted) system.

The misalignment of a gear coupling in a multirotor system is an important problem; it can cause various faults. In the present work the non-linear coupled lateral torsional vibration model of rotor-bearing-gear coupling system is developed based on the engagement conditions of gear couplings. Theor
