ABSTRACT: This final report documents these nine tests. Volume I, Pre-Impact Determination of Vehicle Properties, summarizes the vehicle properties obtained prior to the impact tests. These vehicle properties were used in computer simulation of the impact tests and included weights, pitch moments of inertia, force deflection characteristics, vertical center of gravity location, and linear dimensions. Volume II, Impact Test Summaries, describes the impact tests. The impact tests were remotely controlled with impact speeds ranging from 3 to 30 mph. An array of approximately 20 high-speed cameras and 50 channels of data, including accelerations, strains, and displacement, documented the impacts. Volume III, Impact Test Summaries Appendix, is an appendix to Volume II. It contains the original data of the impact test.
