Finite Element Dynamic Analysis of Mixed Rotating and Non-Rotating Structural Systems

摘要

A finite element model for the dynamic analysis of mixed rotating and non-rotating structural systems is developed. The model is capable of predicting the natural frequencies, vibration modes, transient response, static stress and dynamic stress of the system. The dynamic coupling between the oscillations of the rotor and bladed discs are considered. The model is an improvement over previously developed models.
