Experimental Application of Advanced Thoracic Instrumentation Techniques to Anthropomorphic Test Devices
Published January 01, 1979 by National Highway Traffic Safety Administration in United States
This paper describes the application of a twelve accelerometer instrumentation array for describing the thoracic response of anthropomorphic test devices (ATD). The instrumentation technique was developed for use in cadaver experiments on thoracic injury and has been adapted for ATD installation. Its purpose is to attempt to register different acceleration signatures for different directions, levels, and time durations of impact by locating the accelerometers around the periphery of the thorax. The location and mounting techniques used for the ATD installation are described.
A series of modifications to the Part 572 ATD to improve the side impact response of the thoracic regions were made. They ranged from slight changes in structure to radical altering of the thoracic lateral dynamic stiffness, mass distribution, and rib linkages. A series of side impact tests were conducted on the modified ATDs to allow comparison of the thoracic responses to that determined in cadaver tests.
