摘要

The report contains the results of the tests performed to verify that the crush characteristics of the Federal Outdoor Impact Laboratory (FOIL) 'breakaway' bogie vehicle are similar to the characteristics of a 1979 Volkswagen Rabbit when impacting a narrow object at 20 mi/h (8.94 m/s). These tests were performed at the FOIL located in McLean, Virginia. The 1979 Volkswagen Rabbits and the 'breakaway' bogie were impacted into a rigid pole that had force gauges located in it to collect the force/crush characteristics of the vehicles. The results of the study are to be used to validate the 1800-lb (817.2 kg) pendulum that is being manufactured for the FOIL. Analysis of the data reveals that the crush characteristics of the 'breakaway' bogie accurately represent those of a Volkswagen Rabbit. In addition to the force/crush data, a method to determine acceleration data from high-speed movies is also presented in the report. The method presents a straightforward process that is comparable with electronic transducer data.
