Paper Abstract

When utilizing high speed motion picture cameras to collect data for engineering analysis the most difficult problem frequently centers around the uncertainty of the event. We have had ample opportunity to establish that the actual photographic problems in vehicle crash testing are relatively simple. However, with high film consumption rates, the camera must be triggered with very precise timing and synchronization becomes the real problem in crash testing. This is especially true with long duration events such as roll-overs. Economy suggests using short film loads, fast action requires high frame rates, and large numbers of cameras precludes manual starting. Some form of automatic triggering is required.
