Comparison of Classical and Operational Transfer Path Analysis in Vehicle NVH Improvement

Abstract:

Two method used in vehicle NVH improvement is discussed in this paper. General comparison is given as an introduction to the classical Transfer Path Analysis (TPA) and Operational Path Analysis (OPA). The different theory of TPA and OPA are presented to give a better understanding of these methods and highlight their capabilities. The limitation of each approach and points of attention are followed. Furthermore, the application of both methods is carried out to show the similarity and difference in results and illustrate the points mentioned before. Suggested conditions for each method are mentioned in the conclusion.
