Production NVH Monitoring and Application on a Window Regulator Assembly Line 2003-01-1706

Quality control of NVH performance of Body and Chassis systems is a challenging task. In-line NVH monitoring is part of a practical solution in many cases. The associated technology is maturing, flexible, and economical. Benefits extend beyond a “safety net” sorting function. This paper presents a general overview of the current state of commercially available technology, and presents an example application of an in-line NVH monitoring system for a window regulator assembly line. A couple specific issues and resulting NVH monitoring techniques are discussed - the use of an enveloping function to highlight a cable interference issue, and the use of a microphone to highlight a motor noise issue in a relatively noisy environment.
