The Behaviour of Instrument Clusters
during High-Speed Crash Testing

Abstract

Previous research [1, 2] has established the ability for the needles of some types of
instrument cluster to remain in position after an impact. However, another researcher
found variable behaviour of instruments [3]. Following our investigation of numerous
makes of instruments a set of 5 criteria was introduced to determine if there was a level of
confidence in the residual reading. One of the criteria was that the vehicle should have
had a predominately frontal impact, as we had not investigated the behaviour in side
impacts in detail. As part of more recent ITAI crash tests a number of instrument clusters
were installed in vehicles to simulate a side impact. Impact speeds were recorded as high
as 120 km/h. The results show that some instrument types will hold their pre-impact
position even during high speed side impacts.
