Component-based transfer path analysis (TPA) for predicting NVH performance

Drivetrain noise is less prominent in hybrid and electric vehicles, making noises from other systems more noticeable. This is challenging automotive OEMs to find technologies that enable target assembly noise predictions from individual component models derived from simulation or test bench measurements to avoid costly and time-consuming design iterations.

A relatively new solution, component-based TPA, enables a quick assessment of many design variants and permanent proactive control of noise, vibration, and harshness (NVH) performance, allowing the early detection of potential NVH issues and system optimization in development.

In this whitepaper you will discover:

• What is component-based TPA and how does it work?
• How automotive manufacturers can accurately predict NVH performance before the first vehicle prototype is built
• The component-based TPA process with an e-motor application case
