European side impact analysis of an electric vehicle was done using the robust design method. In order to minimize VC as well as rib deflection, the injury response table which consists of rib deflection and VC response table has been introduced. The sensitivities and interactions are almost the same when it was compared with those of rib deflection and VC response table. Using internal energy of the factors, the starting time of dummy rib deflection and the contact average velocity, the internal energy and time-velocity response table were introduced. It is shown that the results of the new response tables have the similar characteristics to those of the Injury response table. It is suggested that the internal energy and time-velocity response table should be utilized to minimize injuries.
