Structure and Padding Optimization for Side Impact Protection 986183
This paper aims to show methods to design and optimize vehicle
side structure and padding to improve side impact protection.
To limit injuries at thorax level, intrusion profile during
impact must perform a negative vertical tilt: a way to obtain this
is to avoid B pillar deforming above R point. A static analysis may
be useful to determine a proper distribution along B pillar axis of
sections'' moments of inertia.
A good structural behavior is necessary but not sufficient to
perform good results in side impact. A proper control of padding
stiffness is very important especially for abdomen protection.
A method to evaluate the stiffness of padding at thorax level is
proposed. A similar method is used to determine failure load of
armrest for abdomen protection.
