A New Method to Extract Substructures for the Multi-Shaft Transmission

Abstract:

Dynamic substructure method has been widely used in analyzing the torsional vibration characteristics of multi-shaft transmission. However, the existing literatures extract substructures of the multi-shaft transmission by treating its gears and shaft as several rotors, resulting in complex displacement coordination relationships and making it difficult to build dynamic model for the whole system. In this paper, a new method to extract substructures of the multi-shaft transmission is proposed when analyzing its torsional vibration characteristics using the dynamic substructure method. The proposed method avoids analyzing the displacement coordination relationships for the gear meshing, making it easier and more effective to establish the dynamic model for multi-shaft transmission.
