Hood design-Week 2
1. HOOD
It is a cover for engine compartment. It is also a very critical component because of the frontal crash & pedistrial safety requirements. Not only pedistrial requirements, but this is the one which disappears the energy outside the car body, rather than sending is inside the car body.
Suport rod - A device for supporting the engine hood of a motor vehicle in its open position by means a rod.
Gas stay - A device for supporting the engine hood of a motor vehicle in its open position by means of an actuator which is activated by gas.
Hood outer and inner pannel thickness is 0.65mm to 0.75mm
The reinforcement thicness will be more & it depends upon the statergy, budget, requirements.
Hing reinforcement thickness is actually small reinforcement so the thickness is 1.5mm
2. Latch trajectory
Latches are mechanical components that allow the temporary joining of moving parts relative to each other. They are actuated to release the coupling and allow the two parts to separate.
Latches reinforcement thickness is 1.0mm
3. Mastic data
Every mastic seal have a tendency of improving the strength locally around 80mm diameter.
It is used to improve the noise, vibrations, & hardness of hood.
Need 5mm gap between two parts to apply mastic.
4. Emboss defination
To decorate with or as if with a raised design.
5. Deep drawing
Deep drawing is the system of converting blank of sheet metallic into a cylindrical bins with a flat or hemispherical base.
it's miles combination of metal forming technique & sheet metal manner.
If the ratio of top to diameter of the product is extra than 0.5 then this drawing operation is referred to as deep drawing.
6. Hemming
Hemming is a sheet steel forming procedure in which sheets are joined via bending it to a hundred and eighty°. car frame panels and automotive elements consisting of deck-lids, trunk-lids, doorways, hoods and tailgates are shaped by hemming system. on this method, normally a sheet is bent with the help of inner sheet in 3 one-of-a-kind degrees.
