Basic Research in Crashworthiness II. Further Refinement in Engine Deflection Concept.

摘要

An engine deflection,front structural modification to a full size autoombile is refined from a concept that was developed within a previous program. The refinement includes use of normal automobile materials in the structure and a significant weight decrease from that utilized on the original concept. Although no operational automobiles were developed in this phase of the overall program,provisions were made for all normal operational requirements. Structural performance of the originally modified vehicles during fixed object collisions was maintained with the refined vehicles. Additional data were obtained for intervehicular tests involving full size automobiles,including both front-to-side and front-to-front impacts between full size automobiles. In addition to results for numerous low speed impacts,data on the performance of the modified front structure during twelve different tests where impact speed ranged from 30 MPH to 60 MPH were developed.
