Reliable noise and vibration data acquisition and processing for automotive applications

Abstract

This paper presents the development and specific adaption of a miniaturized autonomous system capable of acquiring and processing measurement data in the automotive field. Main focus is put on the reliable determination and evaluation of on-board noise and vibration data. The design of the data acquisition system hardware, the firmware and the graphical user interface are presented. Measurement results for an up-to-date application in automotive industry - the measurement of ventilation noise in a fully electric vehicle - are provided.
