Study on vehicle body structure deformation modes in frontal crash

Abstract

The response of collision velocity waveform to structure deformation in parts dynamic impact simulation was first analyzed in this paper, and a method of deriving structure deformation order by velocity waveform was then determined. By analyzing the relationship between longitudinal rail structure deformation modes and collision velocity waveform in vehicle impact simulation, the reliability of a method of reversely deriving structure deformation modes through speed waveform was verified afterwards. Finally this method was applied in vehicle collision test and the deformation modes of longitudinal rail structure were derived accurately which could provide reference for optimizations of car body structure subsequently. © Springer-Verlag 2013.
