Project 1 Hood
You will work on a detailed report about the Hood Design includes a detailed explanation about the hood and its components, Latch trajectory, Mastic data, Emboss definitions, manufacturing process like deep drawing, hemming, etc. and all the parameters followed in the design.
ANS:- Hood falls under the crumple zone. So it needs to design with lower thickness material. Following are some points to consider while designing:-
1. Latch trajectory is circular path with radius equals to distance between axis of hinges and center of locker. Locker in the hoods follows this trajectory while opening of hood.
2. Mastic points are points to attach outer and inner hood with glue. We need to intersect 80 mm diameter circles drawn around mastic points for better strength. There are generally provided around center embosses.
3. Embosses:- It is metal forming operation in which sheet metal is drawn to form shallow surface which is use for various applications. There are various types of embosses provided for different type of applications. V and Y embosses are provided to protect pedestrian from major impact and to transfer forces to hinges. Latch emboss is use to fit the latch. While hinges embosses are provided to fix hinges. All the embosses are of 5mm height with 25 degree of slanted edges.
4. Hemming:- It is bending process in which bend of 180 degree is produced. We use hemming to inclose inner panel by hemming to outer panel.
5. Drawing:- It is process to form sheet metal in particular shape. We use punch and die to form specific shape on sheet metal.
Learnings:- I need to update NX7 to NX12. Beacuse there are various features and easiness which is not in NX7. I got various errors while first time working on surfacing tools, but there are not enough material on you tube which can resolve my problems. Due to such a error I cannot thicken outer panel and cannot emboss with emboss comand, even I tried my best. So please kindly guide me over that. Even i have design reinforcements but cannot assemble it, becuase didn't get peoper knowledge on you tube. Thanks Sir.
