Application Note: The PSV-400-3D For Car Body Structural Dynamics Testing

DaimlerChrysler studied the suitability of the PSV-400-3D Three Dimensional Scanning Vibrometer for data acquisition in car body modal testing at their facility in Sindelfingen, Germany. The result of their real-world test was very good news for auto body designers around the world. Essentially, the PSV-400-3D can make the same measurements as accelerometers but quicker and more accurately, cutting modal testing costs substantially. Furthermore, it adds all the advantages of laser scanning vibrometry such as high spatial resolution, non-contact measurements, rapid setup and ease of use. This application note summarizes DaimlerChrysler's technique and measurement results.
