Hood design-Week 2

Design of Hood referining the master sample.

HOOD

  The hood of car is an important component of its design , as it is the first line of defense against the elements. The hood is typically made of steel and is designed to protect the engine and other vital components from dust ,debris amd moisture . additionally the hood act as a shield against impact and helps to keep the engine and other components safe in the event of an accident by providing protection to the engine, The hood helps to keep the car performing optimally and reduce the coat of reparis.

HOOD INNER PANEL

The hood inner panel is typically made of light weight material , it is desinged with  emposses , where emposses are small raised areas , usually in the shape of circle , that often found on the inner panels of hoods , they are used to provide a better grip when lifting or handling the hood , and to reduce the chances of it sliding while being moved.

Make the hood to be light weight and easy to open close the hood by human being. it plays the mager roll on car performance with it speed of air flows.

HOOD OUTER PANEL

 The hood outer panel is should be designed on stylish and saftey related points ,where if style is nice means it improve the sales of the car ansd majorly need to consentrat on the sateys .

HOOD LATCH

 Hood Latch is mechanical  latching systems for hoods , where used to hold the hood which not allow to open , basically a lock. It is usually composed of two pieces A spring -loaded catch that attaches to the hood and catch plate that attaches to the body the car.

                                                      

HINGE

 Hinge is a mechanical device where fixed in car front body and hood panel , which is used to open and close  the hood panel for acess the engine component of car.

                                           

REINFORCEMENT 

The Reinforcment is ussed to make strong of hood panel areas which are weak. The use of stiffening material to increase the strength and rigidity of the hood panel . this is done to prevent the hood from flexing or warping in high speed . It also helps to provide a strong seal between the hood and the rest of the car body.

     

MASTIC DATA

The mastic are sealants are used to join inner and ouer panel as weilding both panel will neglect the elegent look of outer panel. where the mastic is used to join both inner hood panel and outer panel hood. The mastic data  plays major rool in the NCAP of saftey crash test .

HEMMMING 

The Hemming is the sheet metal forming process in which sheets are joined by bending it usually to 180degree , where it will give the additional joining process of inner hood panel and outer hood panel.

PARAMETERS USED FOR DESIGN  

Offset, Boundary sketch, Parallel curve, Extrude, Edge Fillt, Split ,Curve smooth, Multi selection surface, Shape fillet, Projection, Sweep, Trim, Symmetric etc.
