Section Modulus calculation and optimization
OBJECTIVE:-
S = I/y
S = Section Modulus
I = Moment of Inertia
y = distance between the neutral axis and the extreme end of the object
SECTION MODULAS:-
- Ratio of minimum moment of inertia of componant to the distance between the neutral axis and the extreme end of the object is called as section modulas
- section modulas is calculation for strenght of componant and plasticity of compnante.
AS PER DESIGN BEFORE MEASURING SECTION MODULAS:-
MOI (max) = 4.814703602e+07 (mm^4)
MOI (min) = 1.560769698e+04 (mm^4)
As per the section modulus equation,
S = I/Y
I = MOI (min) value is considered
Y = Total distance /2, Total distance =876.2742mm
Y = 876.2742/ 2
= 438.1371 mm
Therefore, S = 1.560769698e+04 mm^4/438.1371 mm
S = 35.622 mm^3
AFTER MEASURING SECTION MODULAS:-
HOOD INNER PANNEL OFFSET TO 0.5MM
MOI (max) =7.191111842e+06 (mm^4)
MOI (min) = 2.473454269e+04 (mm^4)
As per the section modulus equation
S = I/Y
I = MOI (min) value is considered
Y = Total distance /2, Total distance =876.2742mm
Y = 876.2742/ 2
= 438.1371 mm
Therefore, S = 1.560769698e+04 mm^4/438.1371 mm
S = 56.4538 mm^3
CONCLUSION:-
- In first case the section modulas is minimum so we get 0.5 mm offset of inner pannel in second case and we get more section modulas as first case .
- More section modulas is good for componant.
