Abstract
The strength of seat belt anchorages should be sufficient to sustain the inertial force of a passenger in a collision accident. In this study, the deformation of a passenger car body subjected to the required seat belt, load specified by safety standards is analysed using MSC/NASTRAN. Global finite element model and more realistic local finite element model are used together. The possibility of fracture is examined from stresses around the weakest anchorage point and experimental fracture test of a clamped circular disk.
