The Study of the Structure for the Head Protection on Front Pillar in Crash or Rollover of the Vehicle

In order to meet FMVSS 201 (U) requirements, the upper vehicle interior structures with trim in a vehicle need to be properly designed to minimize injuries when head impacts these components. This paper presents a study of countermeasures in pillars using FEA approach by considering some design factors. Optimal designs are then selected for interior head impact protection based on CAE analysis using LS-DYNA non-linear finite element code.
