| Summary: | This paper discusses in detail on the behaviour of T-frame under specific loading obtained experimentally to
investigate the deflection of the vehicle B-pillar. A series of T-frame were designed with inner diaphragm at
various location in the sill member in order to investigate the effect of inner diaphragm and non-continuous
closed hat section in the sill member. These two types of specimens were employed to show the effects of
different types of sill member on the stiffness of the overall structure. The finite element analysis and
experimental test were carried out on the in-plane bending. The experimental results were compared with the
finite element analysis results to demonstrate the effectiveness of the inner diaphragm in the automotive B-pillar. Based on the results obtained from the experimental work, location of baffles for the specimens do not gives any major influences for in-plane bending case due to the shape and direction baffles are not suitable.
From the results, the specimen with baffles located at the weld line is stiffer than the other specimens. |
