Roof challenge
Objective: For the give Roof styling, develop the essential flanges and reinforcements, Provide appropriate dimension and check for Draft analysis and also submit your section modulus report on a 0-Y section. Start with the creation of roof ditch area the tool opening angle is only 3 degree. Do a curvature study on the roof and perform calculations to determine the position of the Bow-roof.
Bow – roof prediction Formula : W = 1.73x10^-3 x L+1.85x10^-8 x (R^2)/t + 1.10x10^-3 x l-2.68 Judgement Condition : OK<2.7mm<NG
L = Roof Length in X-Direction[mm](Roof dimension in 0-Y)
R = Roof curvature
R = 2(Rx*Ry)/(Rx+Ry)
Rx = X curvature
Ry = Y curvature
t = Roof plate thickness [mm]
l = Bow Roof Span [mm]
Solution:
I made the roof, with front roof rails, rear roof rails, 2 bow roofs, and center reinforcement. Given below are the various images about the project:
The bow roofs and reinforcements:
A closer look:
The section analysis of bow roofs:
The section analysis of rear and front roof rails respectively:
As part of the project, the curvature study was also done using the heat distortion formula. The details of which is attached below:
