A Consideration of the Transfer Path Analysis Method Based on GTDT

Abstract

In the design of the mechanical structure, the improvement of noise and vibration (NV) is important. The transfer path analysis (TPA) is the method which is widely used for the purpose of solving NV problems. It provides the way to analyze the system under the excitation. In this paper, applying the TPA based on the GTDT method to a simple finite element method (FEM) model, we try making the improvement of vibration characteristics of the model and consider the characteristics and the drawbacks of the GTDT method.
