Paper Abstract

Laser methods are being applied to automotive seat vibration testing methods. The ability to perform non-contact tests is very useful when test specimens are handmade prototypes which cannot be damaged. More importantly, the low input force levels required by laser vibrometers results in more linear response from seats during modal tests; low input force levels limit the effect of freeplay in the recliner and tracks. Finally, the absence of mass loading allows exploring the dynamic interaction of the cover and frame.
