Internal Reinforcement location could be lead to an efficient performance increase.Material distribution in the BIW considering the bending & torsion stiffness of the BIW. Effective load paths in the BIW architecture with a minimum number of components in the design.The Princip les that should always be Considered in BIW designs are: MAJ OR INFLUENCING FACTORS OF BIW DESIGN:
In the new advanced BIW architecture, the entire body was designed with 58 major parts. Exploded view of BIW componentsĪs shown in Figure 1, In general, the BIW consists of nearly 300 - 350 components.
BIW constitutes about 27% of a car’s weight.įigure 1.The panels are stamped into shape and then the spot is welded together. The structure is made from Steel or Aluminium panels (0.7 - 2.0 mm thickness).BIW design also needs to be lightweight structure so that there can be a possibility of reduced fuel consumption & increased performance.Further, it needs to resist & absorb energy during the event of a vehicle crash. The BIW design needs to be stiff to support the mass & securely keep them all integrated. BIW encloses, protects the passengers & cargo.BIW connected all the components in the vehicle like Powertrain, driveline. To achieve an efficient car design it is necessary to have the BIW design with optimized mass.BIW structure supports the overall other subsystems in the vehicle. BIW is the steel structural shell composed of generally steel panels welded together. The structural performance of an automobile can be determined by the performance of the body, referred to as BIW.The stage in automotive design or automobile manufacturing in which the car body sheet metal components are been assembled by welding & by another joining process.BIW refers to the welded sheet metal components which form the structure of the vehicle to which the other components (like engine, chassis, exterior & interior trims) will be married or assembled.
