Accurate Frequency Response Function (FRF) test data has become an essential element in obtaining accurate, representative models of components and assemblies in the Noise Vibration & Harshness (NVH) domain engineering.

We have created a video showcasing several stories. These stories show how to accurately measure FRFs datasets. This enables product engineers to build highly accurate virtual models. Increased realistic models makes design decisions more reliable.

We will be discussing Simcenter testing solutions in the data collection part of each video . We pay special attention to the Simcenter Qsources acoustic and structural exciters. Demonstrations of acoustic sources to capture acoustic Transfer Functions will also be shown, as well as vibro-acoustic Frequency Response Functions. Structural inertia shakers are used to capture reciprocal FRFs and structural FRF sets for modal analysis.

Several CAE models use this test data for either model validation and correlation or to improve the accuracy of the model with limited time.
