Roof Design
Introduction:
An automobile roof is the portion of an automobile that sits above the passenger compartment, protecting the vehicle occupants from sun, wind, rain, and other external elements. Though it just looks like a styling surface that protects from sun, wind and other elements, various environmental conditions are taken into account for designing of the same. Vehicle roof can be subjected to high heat conditions or load during snowy conditions. This ensures the safety of the passengers in the vehicle.
Objective:
The main objective of the project is to design a roof and roof reinforcements from the styling surface received. After the design is done, heat load and snow load calculations will be done on the 0Y section of the roof.
Front Roof rail:
This is the reinforcement provided at front. This part is joined to BIW body and windshield. Visibility criteria is taken in account for joining it with windshield. It is fixed to BIW with spot welds and roof surface is attached with the help of mastic sealants. A draft angle is provided for deep drawing operation. Draft analysis is also done on the section to check its manufacturing ability.
Bow roof 1:
It is an additional reinforcement provided to increase the strength of the roof. It is fixed with roof body with mastic sealants.
Centre rail roof:
Centre rail roof can be considered as reinforcement joining the left and right part of the roof. It is fixed to roof by mastic sealants and to BIW by spot welds.
Bow roof 2:
It is similar to the bow roof 1 provided for better strength.
Rear Roof rail:
It is the reinforcement provided at rear side of the roof. Backdoor and bodyside panels are attached with this part. It is also attached with mastic sealants and spot welds.
