An automotive Tier 1 supplier of driveline parts asked Sound Answers to provide NVH production test system support, which included the development of fault identification (pass/fail criteria) and the integration of a B&K Pulse system in the customer’s end of line production test system. Operating noise and vibration measurements were conducted on the end of line test stand at the customer’s facility in Germany. Types of analysis used included spectral, order, envelope, octave, and time domain. The new NVH production test system has increased the customer’s ability to prevent noise and vibration related faults. In addition, the objective data obtained from faulty units have provided the customer with valuable information to assist in achieving quality improvements.
