Data adquisition system development for on road measurements in heavy vehicle frames

Abstract

Many different methodologies have been used for heavy vehicle frames design, whose goal is to optimize the predicted frame behavior. On road measurements will allow to increase the precision when predicting the stress and strain on the frame. Keeping the abovementioned information in mind, and given the importance of this process, our research group concluded it is necessary to develop a Data Acquisition System capable to carry out this task both quickly and accurately. This paper will show the developing of the Data Acquisition System used in several on road test of a semitrailer frame at Applus IDIADA test track. Th is report will explain all of the possibilities that the testing offers from data capture to its processing and analysis.
