Dynamical measurements in vehicles by transputer technology

Abstract

The experimental validation of mechanical models in vehicle dynamics requires dynamical measurements while driving. Parallel processing using transputer technology allows long time measurements at high sampling rate without any loss of data as well as online computatlon resulting in a very efficient tool for vibration monitoring and parameter identification of vehicle systems. The paper presents the realization of a mobile data acquisition sytem based on transputer technology and some applications of the system to vibration monitoring and identification of a rolling unbalanced vehicle wheel. The measurements are performed with a standard passenger car of a German trademark.
