The final vibro-acoustic testing of car components such as engines and gearboxes is now firmly anchored in quality assurance concepts. The reason for this is the need for objective NVH testing. This data helps to increase production line quality and enables a rapid amortization of vibro-acoustic tests. As a result, the supplier improves its position with car manufacturers through high quality standards.
This white paper describes how the measurement chain is defined based on physical relationships and how complex vibro-acoustic tests for production lines are implemented.
