Observations from repeatable dynamic rollover tests

In an attempt to understand the relastionship between quasi-static and dynamic test results, repeatable, dynamic rollover tests were conducted on production vehicles to determine intrusion and intrusion velocities using the Jordan River Rollover System.These tests included complete production vehicles and body bucks at reduced weight, to vary the roof strength-to-weight ratio.Data from these tests are compared with the results of quasi-static roof strength tests measured at greater roll and pitch angles than are used in FMVSS 216. Biomechanical data indicate that serious head, face, neck, or thoracic spine injuries are a consequence of rapid impacts with significant amplitude.The test data suggest a correlation between quasi-static roof strength and dynamic roof intrusion velocity.Localized failures (buckling and collapse of structural elements that often translate into the roof panel) are a more critical aspect of roof performance than its strength measured in FMVSS 216.
