Hood design-Week 2
AIM:
- TO Design Hood Outer Panel, Inner Panel and the necessary reinforcements by following the Master Section mentioned with the Design parameters.
- Design a hood that satisfies the manufacturing requriements,functional requirements as per euro NCAP standard.

DESIGN DESCRIPTION:
- MANUFACTURING FEASIBILITY-
The following process like blanking,stretch forming,trimming,punching or deburring, welding grinding painting,baking polishing, waxing,coating are involved in manufacturing of hood so, the 4M factor should controlled specifically.
- POSITIONING OF STRIKER-
The striker should be assembled in such way that it placed at the center of the hood for locking mechanism.
- POSITIONING OF HINGE-
The hinge should place in such way that it fix to the car fender at convient position in order maintain the opening and closing of the hood.
- PASSENGER SAFETY-
while driving the car,by any chance if car crush in some accidental situation the hood should designed in such way that the collision force should be transfered to the side fender of the car, sinnce the force diverted the force to the passenger should be less,moment of inertia will be less.
- PEDESTRIAN SAFETY-
For the pedestrian safety, the hood of the car is to be designed in such way that if the pedestrian head hit the hood outer panel in any situation of accidential,the person should not affected more,in order to attain this safety the hood inner panel pattern cut sheet should be punched.so it will be given less impact to pedestrian.
MANUFACTURING PROCESS-
- DEEP DRAWING
A sheet metal forming process in which a sheet metalblank is radially drawn into forming die by the mechanical action of punching.
For hood deep drawing process it is a typical process which in need labour, therefore labour cost intiated for manufacturing.
HEMMING-
- Hemming is a technology used in automotive industry to join the outer panel and inner panel.
- it is the process of bending/folding the flange of the outer panel over the inner panel.
- in this hood design, hemming glue is used for the sealent thus it arrest the water.
MASTIC SEALANT-
MASTIC SEALANT is placed on the mastic seal point which is with the circular edge, this circular point are placed all over the hood to improve NVH.
RESULT:
Finally Designed the Hood Outer Panel, Inner Panel and the necessary reinforcements by following the Master Section mentioned with the Design parameters.
