Hood design-Week 2
HOOD DESIGN
A hood of a car contain two major parts , inner panel and outer panel.this two are attached by a process called hemming.
The outer panel is the skin part of the hoood were similar to class A , the inner panel contain several embossing and cuttings inoerder to give maximum strength to the hood. The hood is locked to the engine compartment by stricker and latch.The mechanism is smoothened by using hinges and held at the top using a support rod or gas stay. the hood head stricker upper limit for different countries are difffernt according the average height of the people.
gas stay is mostly used in premium vehicles
The stricker is mounted on the innner panel of the hood and the latch is mounted on the engine compartment.
simlarly the hinges are mounted on the inner panel and the engine compartment .
To avoid the vibration and ensure the strength we use mastic which is spotted on the inner panel and then expands and hold the outer panel .
mastic points and its affected region.
While designing the hood we should not only ensure the safety of the passengers but also the safety of the pedallers on the road.
In case if someone hit their vehicle on anyone the casuality should be minimum.that may varies by car to car and adult to children.
There are some ranking based on this safety features.
Inorder to design the hood inner panel we first created a surface siilar to the outer panel using wave geometry linker.
then offest the surface with respect to the master section given .The boundary of the panel is then extracted and offsetted using the offset
tool and project curve tool.then the surface is trimmed using surface trim.
After offsetting and trimming the surfaces are joined using through curve. Then filleted after sewing . The hemming and cutting is the done
as per our desing. we can desing in our own way by reducing the casuality and maximum safety.
Then hemming is done as per the values given by the same commands.After that we thicken both the inner panel and outer panel .75 mm
.The area were stricker and hinges mounetd ,we give a thickness of 1.5 mm which is called reinforcement
