Abstract

The occupant kinematics in the pre-crash phase influences their kinematics in the in-crash phase. Active Human Body models (HBMs), which are available in Finite Element (FE) and Multibody (MB) codes, can be used for simulation. As the pre-crash phase usually lasts a few seconds, it causes high computational costs for FE codes. On the other hand, the level of detail in FE models might be an advantage for in-crash assessment. One possibility is to simulate the pre-crash phase with an MB HBM and transfer its kinematics to an FE HBM at the beginning of the in-crash phase. This study presents a method to transfer the kinematics from pre- to in-crash simulation between an MB and an FE model.
