Abstract
An occupant motion system for managing multiple simulations runs, enabling crash-induced occupant motion to be analyzed across variations in crash conditions and other variables. The system uses a computer system configured to accept multiple values or statistical distributions for input parameters based on an analysis type selected by the user. By automating the specification of input parameters into an occupant simulation system, multiple crash scenarios can be analyzed simultaneously and statistical results can be produced for the occupant motion in a particular crash.
