Section Modulus calculation and optimization

Objective: TO calculate Section Modulus & optimizing section.

now, we do calculate the section using NX_CAD.b and we get a 3d curve. using this we will create a sketch using project curve.

now creating sketch:

and we take only outer most curve and join to make it close curve only.

by using section inertia tool calculating inertia :

now calculation centeroid of the section : i.e. = y

=485.9667/2= 242.98335

Section modulus = I / Y =

S1(max)= 8.569550339*10^5 mm2

S1(min)= 5.971373145*10^3 mm2

this is our, initial section modulus max & min.

Optimizing the section:

we will trying to change / increase the section, i have offset inner pane by 0.5 by some sectioon only and hence i have another increased section :

calculation inertia :

S2(max)= 8.581165723*10^5 mm2

S2(min)= 6.204287187*10^3 mm2

hence, S2>S1 which states , material secion modulus increases the strength of the structure increases
