Hood design-Week 2

Aim : Design hood outer panel,hood inner panel and necessory reinforcements by following the mastersection mentioned with the design parameters

Hood and its components

Hood outer panel

the outer panel is responcible for aesthatic of the car and its a metal part

Hood inner panel

Inner panel provide strength and support for the panel and the force distribution on imapct is also done in inner panel

Hinges

hinges help in the rotaional motion of the hood during the opening and clossing of the hood

striker

it helps to lock the hood to avoid accidental opening of the hood

Latch trajectory

this fig shows the rotational motion of the hood

mastic points

mastic helps in improving the strength of the hood

the above marked shapes are mastic this provide support to the 80mm radius around the point thier will be multiple mastic points to provide support

Design parameters

outer and inner panel thickness .75mm

reinforcement thickness 1.5mm

Hemming

hemming is process pf fitting two surface by elongating the outer surface and bending this elongated portion to the inner part to fix it

distance at the edges are reduced to provide proper fitting

Embossing

its the process of producing sunken or raised surface in sheet metal it increase the stiffnes of the part

Final Assembly
