Review of Existing Repeatable Vehicle Rollover Dynamic Physical Testing Methods
Two repeatable dynamic rollover performance testing systems have been demonstrated and reported upon. Here a review of each system is presented in which the general characteristics of each system are discussed. To assess how the results obtained from the two systems would compare, finite element models of rollover tests characterizing the two design approaches were utilized. The results from a published rollover test using one of the systems was utilized as a reference test. For each system, the vehicle rollover impacts were simulated under the same initial impact conditions. The results of the simulations were then compared. It was found that the simulations for both hardware systems produced results that were consistent with each other using state-of-the-art finite element analysis tools.
