Abstract

occurs, the PV often remains engaged with the CMV to their final rest position.  Evaluating an appropriate post-impact drag factor requires assessing the frictional contribution of both vehicles.  Two crash tests were conducted in which a stationary PV was struck by a CMV traveling at approximately 40 mph (64 kph) in order to assess the overall post-impact drag factor.  It was found that the combined units slowed at a rate higher than the CMV alone, but lower than the skidding value of the passenger vehicle alone, and commensurate with the mass-ratio of the two vehicles involved.  Standard crash analysis techniques were found to accurately predict the CMV’s pre-crash speed.
