Hood design-Week 2

HOOD DESIGN:

AIM:

• To design the Hood or Bonet of the front driving car by using the master section and standard procedure which is used in the OEM Manufacturer's.

GIVEN MASTER SECTION:

HOOD:

• Hood is the component which is placed over the engine compartment. The design of the hood is not only to enhance the look of the car, it also improves the aerodynamics of the car and the proper design which ensure the pedestrain safety.It is an access panel to the engine compartment to enable maintenance of power train, drive belts, battery, fluid levels and lamp units.

Design considerations:

The human comfort factor for automobile design is first consideration. It is a method to safeguard and protect space for the human user and necessary components that make up the vehicle being designed. All safety regulations are ensured during this process. Ergonomical consideration consist of Hood clearance, Hood Opening angle and location of support rod or gas stay.

Hood opening angle is different for different regions or countries. It is decided by the average height of the human in that particular country.

Inner Panel:

• In the inner panel only we can research & implement the safety of pedestrians & as well as the driver In this panel only we can attach the reinforcement, embossed,mastic points etc.
• It is an object of the present invention to provide a hood inner panel capable of reduction of a reaction force of the hood inner panel even if a levelof deformat ion of a hood of a vehicle increases,& ensuring a sufficient energy absorption capacity.

Outer Panel:

We can also call it as cover of inner panel. It is the part,which gives luxurious look to the hood or bonnet. Outer & inner panel can not join by any welding process like spot welding or rivet,which spoil the outer look of a car.The outer panel is generally extracted modelfrom the prototype design.

Hinge Assembly:

Hinge is a component that fixes the hood to the fenders of the car. The latch must be fixed perpendicular to the hinge axis so that the hood opens or closes properly.

LATCH & STRIKER:

• Latch & striker is used for locking the hood with the car. it's usually placed on the space provided on the inner panel.

Now Hemming process:

Hemming process is used maintain the aesthatic surface of the hood, we couldnt use the outter hood for welding or any bolt joints, so hemming process is used which we bend the outer surface metal and the manufacturing process is rolling over the sheet metal to fix with inner surface.

FINAL ASSEMBLY:
