Hood design-Week 2

CAR HOOD DESIGN:

Aim:

To design a car hood with reference to the given master section and styling surface given by styling team. It is created with base of safety measures by development team. 

The tasks to be performed:

• Creating hood inner panel with reference to the master section and adding the embosses for strengthening purpose.
• Creating hood outer panel with styling suface and make the hemming region for manufacturing processes. 
• Make a position of hinge and stricker properly. 
• Providing a mastic data for pasting outer and inner panel together. 
• Creating a detailed report about car hood designing. 

Given data for creating hood:

• Outer panel thickness: 0.75mm
• Inner panel thickness: 0.75mm
• Reinforcement thickness: 1.5mm

Car Hood:

Introduction:

• It is hinged at front or rear area edge of the car biw body. 
• It is protect the engine assembly area and give asthetic look to the car
• It is a main part of pedestrian safety
• It gives aerodynamics to the car

HOOD MAIN PARTS:

• Inner panel
• Outer panel
• Reinforcement
• Embosses
• Latch and stricker mechanism
• Mastic sealant

Detail of the parts:

INNER PANEL:

Here given thicknesses is 0.75mm, it had embosses for stiffness and strongness of the hood.we are giving Y embosses for force distribution, because it diverts the force inside the inner panel efficiently.The holes given in a hood is gives more stiffness and strongness.

Outer panel:

It is a protection cover of inner panel, it was combine with inner panel by hemming process.It is a outer aesthetic of the car, the surface was design by a styling team.It is also have 0.75mm thickness. 

Embosses:

It give more strength to the inner panel, and it gives also for aerodynamic property to the car, after using geometric master section we will make the embosses for strengthening purpose. 

Mastic sealant:

Mastic sealant is use for stick the outer and inner panel, the inner panel had mastic region for applying sealant.

Hemming process:

Hemming process is used for joining outer and inner panel by folding the edges of outer panel to the inner panel, at the corner of folding edges have given minimal area because to make manufacturing processes easier. 

Position of hinge and stricker:

To positioning hinge and stricker tragetry point of hinge and stricker in one single tangencial point, it should be maintain because then only it will close smoothly.

Reinforcement things:

We need to give reinforcement for hinge and stricker for strengthening the parts of joining and locking point of the hood.it should be maintain 1.2mm thickness. 

Conclusion:

As per given data we develop the hood design with master section, hemming data and assemble all part together in the final output.
