Section Modulus calculation and optimization

#4 Section Modulus Calculation and Optimization

Scope

To Designed and Developed Hood as to analyze the section inertia analyse to detemine the Moment of inertia. The section modulus is proportion to the Moment of inertia and inversely proportional to Distance ( between the neutral axis and the extreme end of the Hood).

Section Modulus

Section Modulus is to measure the intersection curve on the Inner and Outer Hood.then Joint those curves and analyse

Section Modulus is to Determine the Resistance of hood against of moment,bending and Twisting.So, higher the value of moment of inertia , have higher resistance to deform under certain load, hence the moment of inertia is directly proportional to the strength of the material , and strength of the material can be calculated with the help of section modulus.

S=I/y

S is Section Modulus

I is Moment of Inertia

y is Distance between the neutral axis and end of the object

Here,Section Modulus calculation as

I_{MAX is} 8.423449X10⁵mm⁴

I_{min is} 4.616495x10³mm⁴

Total length of 'Y' value was 488.7mm

The Reference axis y is Y/2=488.7/2=244.35mm

Trail 1 : Section modulus(S)max =8.423449X10⁵mm⁴/244.35mm

Maximum of section Modulus =3.447X10³mm³

Section modulus(S)min=4.616495x10³mm⁴/244.35mm

Minimum of section Modulus =0.018x10³mm³

So the strength of an hood is from 0.018x10³mm³to 3.447X10³mm³

Now we do one more section modulus analyse,by offsetting the inner Hood 0.5mm outward to the outer Hood.

Trail 2 : Section modulus(S) max =9.598003X10⁵mm⁴/244.35mm

Maximum of section Modulus =3.927X10³mm³

Section modulus(S) min=5.580716x10³mm⁴/244.35mm

Minimum of section Modulus =0.022x10³mm³

So the strength of an hood is from 0.022x10³mm³to 3.927X10³mm³

We did 2 trail in the section modulus analysis

from the calculation of Trail 1 section modulus is S min is 3.447X10³mm³ and S min is 0.018x10³mm³

Trail 2 section Modulus is S min is 3.927X10³mm³ and S min is 0.022x10³mm³

We compared to Trail 1 and Trail 2,Section Modulus Trail 2 is increase the strength of the Hood by offesetting of 0.5mm

Result

The design of hood is being on various factor.On those Moment of inertia is more important to determine the strengthen of the hood is withstand by load and moment.
