The design of vehicle and vehicle safety equipment has been for many years evaluated with respect to safety for dummies. A large number of impact simulations with different dummies have shown a wide range of possible dynamic response for the same type of external load. It is obvious that the dynamic response and injuries exceed the range of expected results. Therefore, it is necessary to study, how human body variability in geometry, proportion, inertia properties and initial position influence the dynamic response and possible injuries. The article presents the results of a study that used the scaling model developed by Madymo. The idea of this approach is to generate a set of target mechanical parameters from the relevant human population and then scale existing values towards desired individual anthropometry. The dynamic response for typical human seat position is calculated by using mathematical model based on anthropomorphic multibody system.
