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.<\/p>\n\n\n\n<p>We will be discussing Simcenter testing solutions in the data collection part of each video . We pay special attention to the <a href=\"https:\/\/www.plm.automation.siemens.com\/global\/en\/products\/simcenter\/qsources.html\" target=\"_blank\" rel=\"noreferrer noopener\">Simcenter Qsources<\/a> 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.<\/p>\n\n\n\n<p>Several CAE models use this test data for either model validation and correlation or to improve the accuracy of the model with limited time. <\/p>\n\n\n\n<p>Curious?
