Full Vehicle Structure-borne Path Analysis

Industry: Automotive

Applications: Standardized Testing

Sound Answers was asked to collect structure-borne data for an automotive OEM to use in a Source-Path-Contribution (SPC) analysis. The SPC analysis helps provide an overall image of the vehicle sensitivities and characterization in terms of noise and vibration. Vibrational acceleration per input force (A/F) Frequency Response Functions were measured using a modally tuned impact hammer. The customer took delivery of the data, and used it in their SPC analysis to quantify the structure-borne paths from key vehicle acoustic and vibration sources to driver response locations.
