Simulation is a very important tool for the
development of occupant protection systems.
At an early stage it is possible to determine
the main deforming processes from the
structural behaviour based on CAE
calculations.
Simulation offers the possibility to view and
optimise the structural behaviour and the
effectiveness of the occupant protection
system as a whole unit.
As well as meeting the legal crash
requirements, the European higher-speed
frontal crash law with increased speed is also
satisfied.
At an impact speed of 64 km/h in an offset
crash the structure of the vehicle remains
stable enough to allow the doors to be easily
opened.
Compared to the legally required speed of
56 km/h this represents approx. 30 % higher
impact energy.
The European side crash requirements (crash
between a moving barrier with deformable
collision body and the stationary vehicle)
were met with high safety standards.
This is achieved through the particularly rigid
cell, the occupants’ survival zone. The
covering of the doors with the posts and the
sill prevents the doors from sliding over into
the passenger compartment.
Despite the low weight of the supporting
structure, deformation in the roof area is very
small, even with the glass module roof, and it
offers excellent rollover protection.
This is due to the intelligent pairing of the
bonding technology and the specific design
of the body parts.
