• Abstract:
  Highway and roadside safety features are crash tested for compliance with certain safety criteria. The Federal Highway Administration (FHWA) uses a surrogate reusable test vehicle, Bogie, to conduct crash tests of roadside safety features. Bogie is intended to replace an impacting vehicle in order to reduce the cost of the test. Bogie can be configured with different crushable impact noses representing various vehicle fronts. Typically, the crushable nose employed by Bogie is a multi-compartment honeycomb material. Different configurations of honeycomb arrangement are considered for different impact velocities. Recently, the advances in crashworthiness and dynamic finite element analysis have allowed considerable modelling and simulation of vehicle impacts with roadside hardware. This paper describes, in detail, the finite element models and the validation of Bogie and its honeycomb material in impacts with an instrumented rigid pole. This model can be exercised in various simulations of crash scenarios for design optimization of roadside hardware. This validation also allows the use of the model for impacts with narrow objects, which is a critical aspect of crashes with roadside safety devices.
