Component-based TPA is one example (here, you can find a related white paper).
The compelling combination of test and simulation enables the NVH engineers to predict the final vehicle NVH performance before assembling the first full prototype. In a nutshell, this technology enables you to predict a component or subsystems behavior prior to integration.
Consequently, it enables the dream to create a virtual vehicle prototype by assembling different components (e.g. electrical engine, suspension system, body, etc.).
Component-based TPA is very powerful concept not only because you may get an accurate prediction of the vehicle NVH behavior in the development stage when implementing design improvements is still easier. But also, the component based TPA enables you to work with a standardized platform to virtually assembly countless vehicle variations with much lower time investments.
