ABSTRACT
Automotive companies aim to reduce development costs and time while minimizing CO2 emissions. Enhancing efficiency in NVH (Noise, Vibration, and Harshness) performance is crucial, as it can prevent late redesigns of body structures or components. Transfer Path Analysis (TPA) is a widely used diagnostic technique to identify the main propagation paths of noise or vibration into the cabin. Blocked force TPA focuses on measuring the loads (force or acoustic load) of a component on the bench.
In this presentation, the results of an experimental campaign using Blocked Force TPA on an e-axle will be discussed, along with a description of the experimental setup used to obtain accurate high-frequency forces.
These loads, which are independent of the bench's mechanical properties, can be transferred to different assemblies, such as future chassis and body structures, to improve the NVH performance forecast of the component when assembled in a car.
