Final vibro-acoustic testing of automotive components such as engines and transmissions 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 fast payback of vibro-acoustic testing. As a result, the supplier improves its position with automotive manufacturers by maintaining high quality standards.
This white paper describes how to define the measurement chain based on physical relationships and implement complex vibro-acoustic tests for production lines.
