? Lightweight parts with load and function-optimized material usage
Implementation
? Flexible Cold-Rolling Process? Flat material with repeated, varying thickness runs and harmonious transition zones
? An increased number of thickness zones for an optimized TRB solution results in minimal lightweight cost
Targets / Benefits
? Weight reduction? Part integration
? Functional Improvement
CAE model information
? Re-engineered model
? Five passenger CUV ; model year 2010
? Updated material for the Door-Ring and Rear
Rails to state of the art
? Curb weight: 4,000 lbs
? Dimensions
– Length: 189”
– Width: 75”
– Height: 63”
? Less deformation concerning the B-Pillar
? Slightly lower SWR because of more deformation of the Roof Rail
? Independent thickness run without requiring a symmetry line
? More homogeneous distribution of the crash energy
? High material utilization
? Weight reduction up to 17 %
Potential of a TRB ? Rear Rail Design
? Simulation with generic vehicle
– FMVSS 301 Rear Crash
– Understructure deformation
– Plastic strain at Fuel Tank
– Door opening
– Stiffness comparison
? Harmonic load distribution due to transition zones
? Reduced production and assembly costs by part integration
? 10 % weight reduction + 1 part integration with TRB ? I
? 21 % weight reduction + 3 parts integration with TRB ? II
