The aim of this study was to assess the feasibility of using a high speed x-ray system (capable of 1000 frames/sec) to evaluate the bony kinematics of post mortem human surrogate (PMHS) cervical spines at real world speeds during frontal impact. Whole body frontal impact sled tests were performed on two fresh PMHS specimens. Screws were inserted into the tips of the spinal processes to optimize contrast on the high speed cine x-ray. Head, T1 and sternum accelerations, as well as shoulder, and lap belt forces were recorded. Vertebral motion was captured using a modified mobile c arm x-ray system, and an image intensifier linked to a high speed camera (Kodak motion corder analyzer, model SR 1000C, Kodak, San Diego, CA, USA) The variable parameters for the tests were camera frame rate and sled velocity. Tests were performed with delta-V’s (Δv) of approximately 15 kph (8G) and 21 kph (10G). Cine x-rays of the tests were recorded at 250, 500 and 1000 frames/sec.

Structural component testing is essential for the development process to have an early knowledge of the real world behaviour of critical structural components in crash load cases. The objective of this work is to show the development for a self-sufficient structural component test bench, which can be used for different side impact crash load cases and can reflect the dynamic behaviour, which current approaches are not able. An existing basic system is used, which includes pneumatic cylinders with a controlled hydraulic brake and was developed for non-structural deformable applications only (mainly occupant assessments). The system is extended with a force-distance control. The method contains the analysis of a whole vehicle FEM simulation to develop a methodology for controlled force transmission with the pneumatic cylinders for a structural component test bench.
