Uncertainty Sources in WorldSID-50M Dummy

Full vehicle crash tests are never fully identical in terms of their results, even when conducted with the same configuration. This variability arises from the existence of a diverse set of uncertain input parameters, which induces uncertainty in the relevant quantities of interest (QoI). The classical engineering approach, dealing with scattering system behavior and QoI, is to introduce safety factors and thus ensuring the system’s robustness with respect to the adherence of performance-relevant criteria. However, using this strategy within the vehicle safety design process carries the risk that the margins to specific limits might be exceeded in initial hardware tests.
