Concept Development in BIW


Following things to be done for development of any BIW product-:

Concept & Feasibility •Concept design / Design support and feasibility study •Concept surface description •Generate master sections and component packaging •Technical surface description (A class) •Deciding part configuration / split lines •Gap & Flush requirement •Feasibility study & simulations •Assembly sequence & develop process diagram & spot plan drawings •Preliminary weight analysis and bill of material

Package analysis •Interior, exterior, engine, underbody, and luggage compartments •Engine and passenger compartments •Closures

Detail Design •Modeling & drafting of vehicle components •Sub assemblies & assemblies: Body in white, closures •Tolerance analysis

Facelifts and Variants •Minor freshening: rub rails, door trims, steering wheels, roof carriers, and decorative trims •Moderate facelifts: bumpers, spoilers, grilles, steering wheels, door trims •Mid-life facelifts: changes in bumpers, lamps, instrument panels & consoles, spoilers, grilles, steering wheels, door trims, new engine, RVMs, BIW changes to suit trim changes •Major Facelifts: carryover platform •Variants: from base hatch back platform to sedan and station wagon with or without W/B increase

Engineering Documentation •Bill of Material generation and controlling •Material specifications •Chain of Dimension, Gap and Flush study and GD&T on drawings •Design Failure Mode Effective Analysis (DFMEA) •Product specifications, Design Validation Plan (DVP) •Fastener selection

3D-engineering, 2D-drawings releases •Body contour development •Design according to tool, manufacturing or process requirements •FMEAs •Data management and Releasing

Geometrical Integration / Digital Mock Up (DMU): •Package •Collisions-check •Design studies
