Title: Evaluation of Passenger’s Trauma Level for Different Crash Pulses
Author(s): Ştefan Tabacu   Ion Tabacu   Mariana Ivănescu   Ionel Vieru      

Abstract: Numerical models are used in order to extract, define and evaluate the passenger’s level of protection. Crash pulses obtained from frontal impact simulations are used to evaluate the passenger’s acceleration level and, therefore, the trauma. Initial safety measures were evaluated and, when necessary, the function improved or additional devices were used. The influence of safety measures is presented providing assistance in applying them.

Keywords: numerical simulation, crash pulse, occupant protection, LS-DYNA.
