Abstract:A full-scale impact test was performed November 16, 1999, at the Federal Railroad Administration’s Transportation
Technology Center, Pueblo, Colorado, by Transportation Technology Center, Inc., a subsidiary of the Association of
American Railroads. The test was performed on a Budd Company Pioneer-type commuter passenger car. The purpose
of the test was to measure strains, accelerations and displacements during the impact and validate the computational
and kinematic models of the vehicle impacting a rigid barrier.
Other test objectives were to determine the crash-force pulse shape throughout the vehicle and to provide a greater
understanding of occupant kinematics in crash situations. Simula Technologies Inc. provided the occupant kinematics
experiments which included a number of instrumented Anthropomorphic Test Devices in different seat configurations.
This report describes the test car and the methodology used to carry out the impact test, together with a description
of all the instrumentation used to measure the structural deformation of the car during the impact.
The impact was recorded by a number of high speed film and video cameras. The report contains a description of
the cameras used, their position. and the subsequent film analysis carried out to measure the displacement and velocity
of the test car during the impact.
The strain, acceleration, velocity and displacement time histories from all the transducers are presented in the
report.
The speed of the test car at impact with the rigid barrier was 35.1 mph and the amount of crush was about 4.5 feet
