Hood design-Week 2

As per the Data given for Designing and Assembly the Hood Outer Panel, Inner Panel and the necessary reinforcements by following the Master Section mentioned with the Design parameters that i will explained now.

1. What is Hood?

The Hood is an opening body panel that covers the engine in a front-engine vehicle.The hood is also considered as a another type of door in a vehicle as it consists of outer panel and inner panel.

The inner panel provides strength while the outer panel functions as the metal cover.

To joining the both Inner and outer panel , the joining process is called as Hemming process or we say HEMMING.

As per the Indian hieght the hood should be opened in between the hieght of 5.5 feet and Europeans are around 6feet.

1. For doing Assembly of the Hood inner, outer ,hinge and striker with latch and reienforcement we should follow some of these steps they are as i will try to follow it:-
2. We should open the NEW FILE in a ASSEMBLY with clicking OK.
3. After opening the Assembly screen on the monitor we should stars too ADD the Differnt Parts such as opter panel, inner panel .
4. And doing FIX CONSTRAINTS on it .
5. Then Hide the unwanted outer panel and atrats to work on the Inner panel as selecting as a working part.
6. TRIM the half of the section whichever is usefull for as a working panel.
7. Then as per the Refering the MASTER SECTION we should use the Assembly commands , Curve commands, and surface commands for the other operations.
8. From this I will explain some of these important commands whichever i learned during this sesion.

As per the MASTER SECTION :-

There are some of these important commands areused for designing they are discussed here below.

OFFSET SURFACE COMMAND:- For offseting the face at the different hieghts as given in the master sections as 1.7 mm,4 mm and 25 mm etc respectively.

OFFSET FACE ON COMMAND:- It is used for offset the curve or a boundary for shifting as it is at a certain distance ginen in the Master Section.

BRIDGE CURVE:- It is used for joining the two end sections for doing the Law extension or Through curve mesh for giving the chamfer for joing two planes of the Inner panel in a well manner.

Through curve/ Mesh:- for joing the two surfaces with each other in a well manner.

Blend command:- Blend is used as the chamfers given to the different corners during the design.Because it is a part of the SHEET METAL and as per that during the manufacturing of the panel, we should use the PUNCHING OPERATION in a differnt stages for Manufacturing process and also for reducing the Manufacturing COST.

EMBOSS COMMAND:- We should as a Emboss command same as like pad command in a Catia or we say extrude also.

Datumn palne:- Datumn plane is the plane which is a one type of the refernce plane which we should create for our guidance purpose.It will be used it in a differnt angle and in a different Curve as per its purpose during assembling or during design a product.

Mirror Geometry/Assembly: as the name suggests it is used for mirroring the part and the whole assembly by using the MIRROR WIZARD ASSEMBLY method.

• During the these all process of desing the ijnner panel we should think about the Mastic points ,Trajectory points whichever is used for paralleling the body interface and for aesthetic view.
• The Mastic circles which is creating ,they are in a same manner, which is paste it by a glue and other items for pasting or joining with each other and in lasty Hemming is done for final attatchment.
• the sheet should be of0.75 mm of size mainly which we should used in the panel manufacturing.

Some of the Cars name i will discussed here which is the best design like TATA VISTA, NEXON, etc.
