Combined vehicle chassis dynamometer and powertrain test stand for NVH development

Kombinierter Fahrzeug- und Aggregateprüfstand für die Akustikentwicklung

  • 65 Accesses

Abstract

Flexibility in the use of facilities is not just an issue for production. A few weeks ago a test stand was commissioned in the R&D centre of Audi AG, which allows acoustic measurements on both complete vehicles and powertrains to be carried out under normal operating conditions. Conversion between these two different test configurations takes place fully automatically within a few minutes, in a similar manner to a change of scenery on stage.
