This paper presents the results of finite element computer simulations of vehicular impacts with a roadside crash cushion. DYNA3D is employed to model the energy dissipating response of the Narrow Connecticut Impact Attenuation System under high speed impacts with heavy vehicles. The finite element predictions are compared with the experimental results of full scale crash tests involving automobiles impacting the device at 97lm/h. It is demonstrated that computer simulations can accurately model the dynamic response of a crash event and provide valuable measures of occupant risk. It is recommended that these simulation tools be employed more extensively in the design of roadside safety features so that the number of expensive full scale crash tests required to develop future hardware can be minimized.
