The time domain sensitivity analysis of System Technology Incorporated's (STI) Tripped Rollover Vehicle Model has been conducted utilizing sensitivity programs developed by the University of Missouri-Columbia. The eight degree of freedom STI tripped rollover model simulates the motion of a vehicle which skids laterally on pavement and then impacts with a curb. The sensitivity of vehicle system parameters and relevant system response variables have been investigated and ranked in order of importance. Based on energy considerations, vehicle rollover prevention energy reserve (RPER) has been derived and used as an indication of vehicle rollover stability. The results reveal that the minimum value of RPER approaches zero at the threshold of rollover and if the minimum falls below zero then vehicle rollover will occur.
