Transfer path analysis is applied to a wide range of industrial products.
By identifying transfer paths and vibration/noise sources and clarifying contributions in response metrics, it is used for countermeasures against issues and for developing successor models, making it an essential technology for analyzing vibration and noise mechanisms.
The transfer path analysis provided by ESTECH supports every product from large structures such as railway vehicles, passenger vehicles, and relatively small structures such as small motor units. With high-precision measurement and analysis technology backed by extensive expertise, we help solve a variety of customer challenges.
What is Transfer Path Analysis?
Transfer path analysis is a method for analyzing the contribution ratio by the evaluation responses for each transfer path from the (vibration/noise) sources. Various methods are available, as follows:
-
Conventional TPA (dynamic stiffness method, inverse matrix method)
-
Operational TPA
-
Assembly TPA
-
Component-based TPA
-
Multiple coherence contribution
Example Application to In-Cabin Noise in Driving Tests
