Abstract
The purpose of this paper is to present a revised approach to estimating the approach energy EA absorbed in an accident. This paper details the revised method for energy estimation for front and rear impacts (side impacts will be discussed in a later publication). The new algorithm originates from the fact that CRASH3 requires an estimate of approach energy absorbed (EA) and not force or stiffness. Therefore, the simplest approach is to model the behavior of EA with residual crush. Data from more than 1000 tests in the NHTSA's data-base are tabulated and presented. Finally, the paper validates the new algorithm by analyzing data from a number of staged collisions. The work reported in this paper was executed under contract to the National Highway Traffic Safety Administration (NHTSA) as a part of their research.
