A Data Acquisition Method for Dynamic Vehicle Testing

This paper discusses the development and construction of a Mobile Telemetry Instrument Facility (MTIF) used for the acquisition of dynamic vehicle test data by the Amerco Technical Center. Objectives of the MTIF are maximum flexibility, highest degree of accuracy, and quickest response during dynamic test activities. The latest data telemetry, recording and reduction technology is incorporated in the facility.

Selection and application of the instrumentation such as light beam oscillographs, Mecca or floating ground systems, environmental control, on-line data analysis and instrument calibration equipment are explained. Also covered are the advantages of such a mobile facility over a permanent operation base.
