DYNAMICAL MEASUREMENTS IN VEHICLES BY TRANSPUTER TECHNOLOGY

The experimental validation of mechanical models in vehicle dynamics r equires dynamical measurements while driving. Parallel processing usin g transputer technology allows long time measurements at high sampling rate without any loss of data as well as online computation resulting in a very efficient tool for vibration monitoring and parameter ident ification of vehicle systems. The paper presents the realization of a mobile data acquisition system 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.
