Hood design-Week 2

HOOD      

          * The hood is an opening body panel that covers the engine in a front engine vehicle 

          * The hood is considerd as a another type of door in  a vehicle as it consist of an outer panel & inner panel 

          * The inner panel provides a strenght while the outer panel functions as the metal cover 

 

COMPONENTS OF HOOD 

                                     1. LATCH TRAJECTORY 

                                     2. MASTIC DATA 

                                     3. EMBOSS 

1. LATCH TRAJECTORY  : It specifically pertains to those latch system on hoods , which when the hood is fully opened                                                  extend at any point above a horizontal plane throgh the uppermost edge of the steering wheel in                                             the straight ahead driving position with the vehicle in a horizontal position 

                                              

2. MASTIC DATA : It can be used to jion almost anything because it will work on any surface . aslo the mastic sealant can                                    act as a protecting layer between elements. 

                                                       

3. EMBOSS :   For designers who need to limit noise, vibration, and harshness (NVH), embossing is an important part of a                             complete thermal-acoustic solution. Appearance. Embossing also helps to hide wrinkles and imperfections in                            materials, improving visual presentation.

                                                 

DEEP DRAWING : Deep drawing is a metal forming operation in which the sheet metal is stretched into a desired shape by                                 the mechanical action of a punch. The punch pushes the sheet metal blank downward and forces it into a                               die cavity which ultimately forms a shape of the desired part.
