Hood design-Week 2

Design and Develop of Hood

Objective

To understand the concept, design and develop Hood outer panel, inner panel and the necessary reinforcements like Emboss, Mastic data, Latch Trajectory, Manufacturing process like Deep drawing and Hemming and also to assembly the Hood outer panel. Inner panel, Latch, Hinge and the Reinforcements.

Dimensions

Hood Thickness Information

• Outer Panel Thickness = 0.75mm
• Inner Panel Thickness = 0.75mm
• Reinforcement Thickness = 1.5mm

Hemming Data

What is Hood?

The Hood is the hinged cover over the engine of vehicles. It is also known as Bonnet. It can open to allow access to the engine compartment on front-engine or rear-engine of the vehicles for maintenance and repair.

Components of the Hood

• Hood Outer Panel

• Hood Inner Panel

• Hinge Re-enforcement

• Latch and Striker Re-enforcement

Latch Trajectory

It is the path which the striker will follow when the hood is open/closed while pivoting on the hinge axis. It is taken as a circle with the hinge axis as the center of the circle. The striker is placed 90 degree such that it is tangent to the circle.

Mastic Data

It is a high-grade construction adhesive and Mastic point are areas where the inner hood panel is joined with the outer panel hem using a mastic glue. This mastic glue keeps the inner panel stuck to the outer panel.

Emboss

Emboss is also known as Stamping in manufacturing industries. It is a process of bending the sheet metal into a shape.

Manufacturing process of Hood Design

• Deep Drawing
• Hemming

Deep Drawing

Hemming

It is a sheet metal forming process in which sheets are joined by bending it to 180°. In this process, usually a sheet is bent with the help of inner sheet in three different stages.

Assembly

Conclusion

I understood the Design concepts of Hood assembly and its components according to process of development the Hood design by using NX CAD and the Given dimension of the Hood master section has designed and developed with Hood outer panel, inner panel with the necessary reinforcements like Emboss, Mastic data, Latch Trajectory, Hemming and also has assembled the Hood outer panel. Inner panel, Latch and Striker, Hinge and the Reinforcements.
