Abstract:

This report contains the test procedures followed and test results from one crash test between a 1997 Geo Metro and a single-leg small sign support. The test was conducted at the Federal Highway Administration's (FHWA) Federal Outdoor Impact Laboratory (FOIL) located at the Turner-Fairbank Highway Research Center (TFHRC) in McLean, Virginia. The target test speed for the test was 100 km/h and the target test inertial weight was 820 kg. A dummy was not used in this crash test. The test was conducted to provide data for validating a finite element model (FEM) of a Geo Metro and to investigate the potential for windshield penetration by the sign support after fracture. Computer simulations using the latest FEMs of a Geo Metro indicated that windshield penetration was possible while striking a small sign support with a sign panel mounting height of 1,525 mm. The results from the test verified the simulation's prediction that if a Geo Metro struck this particular sign support design with these material properties there was a high probability of windshield penetration or severe windshield/roof damage. Because the post fractured, other important safety performance measures including predictability of device activation and longitudinal occupant impact velocity met the safety performance criteria specified in the National Cooperative Highway Research Program (NCHRP) Report 350, test designation 3-61. The data and high-speed film coverage will aid in the continuing evolution of the Geo Metro FEM.
