Crash Tests: Tests used for development and validation of the models.
To date the accuracy of the combined tractor-semitrailer model has been assessed by comparing analysis results against three full scale crash tests.
This test was run using a 1992 FLD120 Freightliner Tractor (without a trailer) impacting a rigid 34-inch concrete F-shape barrier at 50 kph (31 mph) at an impact angle of 25 degrees. The tractor's mass was 14,683 lbs, and its wheelbase was 215 inches.
The test involved a 79,705-lb (36,153-kg) tractor-semitrailer vehicle impacting a concrete median barrier at 52.7 mph (84.9 km/hr) and impact angle of 15.4 degrees. The test vehicle was a 1991 White GMC tractor with a 1988 Pines 48-ft (14.6-m) semitrailer. The test article was a 42 inch (1.067 m) tall concrete median barrier with an installation length of 200 ft (60.9 m).
The test involved a 1979 International TranStar 4200 tractor with a 1977 Pullman van-trailer ballasted to 50,050 lb (22723 kg) impacting the barrier at 51.4 miles per hour (82.7 km/hr) and 16.2 degrees. The installation length of the barrier was 100 ft (30 m), and the impact point was 24 ft (7.3 m) from the upstream end.
