Roof challenge

Objective:

1. To design the Automotive Roof based on the given styling surface and to analyze the prepared model to check the manufacturability and the feasibility of the design.
2. To perform the section modulus study for the master sections and create for the Front roof rail, Rear roof rail, Bow roofs and center roof rail.

The roof consists of the following parts

1. Front roof rail
2. Rear roof rail
3. Bow roof rail 1
4. Bow roof rail 2
5. Reinforcement center rail

MASTER SECTION OF FRONT ROOF RAIL

REAR ROOF RAIL MASTER SECTION

BOW ROOF RAIL

Bow roof center 1 is an additional stiffening member used in the roof assembly for the localised strength improvement and it is join directly to roof itself with several spot welding or even with mastic sealant.

Here we used 2 bow roofs for better load carrying capacity.

REINFORCEMENT CENTER RAIL

Center roof rail or reinforcement center is used as a cross member between bodyside left hand and right hand respectively. In some cases, the reinforcement center is not joined with the roof and in some other cases, it is made to join in both roof and bodyside. The reinforcement center and Bow roof are joined either spot weld or by mastic sealants.

Here in this assignment, I failed to do the curvature study of the roof as I was lacking time.

Please do consider my marks for the work done here. I promise to definitely learn the remaining part and report it to my corresponding support engineer.
