Section Modulus calculation and optimization

CALCULATING SECTION MODULUS AND OPTIMIZATION

Aim:

To calculate secion modulus for given hood and optimize it to get choose which one is better strength.

Section modulus:

S=I/Y

Where S=section modulus

I=Moment of inertia( max or min)

Y=Distance between neutral axis and extreme end of hood

The unit is mm^3.

Calulaton of Y:

Y=486.5 / 2

Y =243.25mm

calculating section modulus before optimization:

As per given hood

S=Imax / Y

S=1.670142522*10^6 / 243.25

S=0.00686595*10^6 mm^3

calculating section modulus after optimization:

In the given hood a change is made by offseting inner panel

S=Imax / Y

S=1.670212635*10^6 / 243.25

S=0.00686624*10^6 mm^3

Conclusion:

By calculating section modulus of before and after optimization for given hood ,after optimization section modulus is greater ,therefore increasing section area gives more strength to hood.
