PRECISION MEASUREMENT TECHNIQUE OF LOADS AND DISPLACEMENTS OVER AN AUTOMOTIVE BODY DURING CRASH TESTING

The Joint Research Centre of the European Commission has obtained some successful results with the application of a large Hopkinson bar bundle (bar transducers) as a precision crash test technique of vehicle body cross sections. The objective of the research reported in this paper was to measure accurately the loads and displacements in some defined critical points of a vehicle body subjected to a crash test in order to use such measurements as reference for the validation of finite element (FE) code predictions. It is anticipated that the eventual validation of crash FE code predictions, by comparison with the results of precision large Hopkinson bar bundle experiments, will lay the basis for considering FE code predictions as alternative, less expensive, reliable crash testing.
