Week 11 Car Crash simulation

OBJECTIVE:

To perform a car crash simulation and perform a parametric study using three different thickness for the car body and analyse the results.

METHODOLOGY:

• First import the geometry and assaign the materials to the wall and the car body.
• give the thickness to the car body.
• apply symmetry to the wall and the car body by selecting the proper edges.
• 
• apply mesh to the geometry and perform face sizing operations wherever needed.
• 
• give the fixed support on the faces of the car body and give the displacement to the wall.
• 
• 
• run the simulation and find the results for various thickness.
• 

CASE 1:THICKNESS=0.3

CASE 2 : THICKNESS=0.5

CASE 3:THICKNESS=0.65

thickness(mm)	total deformation(mm)	equivalent stress(Mpa)
0.3	886.79	19002
0.5	876.32	12480
0.65	885.3	10206

CONCLUSION:

from the above data we conclude that as the thickness of the geometry increases results in increase in mass hence stress developed in the component decreases .
