The accurate recording of dynamic data in a hostile environment has been a challenge since this type of data has been recorded. Based on the technology developed for a computer-controlled data system for processing and storing dynamic data measured on manikins during aircraft ejection tests, a small, ruggedized high speed data logger has been developed. This small, lightweight (1+ pounds) battery-powered recorder samples data up to 10,000 samples per second, recording times up to 100 seconds for eight analog sensor signals and five event signals. This recorder has the advantage of not requiring a hard ground line link which can restrict the dynamic motions of the object being tested. While this system has been developed for recording dynamic data in many different hazardous environments, its initial use for recording data during automotive/motorcycle crash investigations will be the subject of this paper. The unique features of the recorder and its adaptability and usefulness in the automotive/motorcycle crash test program will be discussed in detail.
