Week 11 Car Crash simulation

CAR CRASH CHALLENGE

OBJECTIVES
In this challenge, we have to perform a parametric study using 3 different values of thickness for the car body. You need to apply the same conditionsas mentioned in the video that corresponds to this challenge. Analyse the total deformation and Equivalent stresses acting on the model.

PROCEDURE
First, we have to input the engineering materials with required properties or else by creating with required properties.

Then we have to import our model into ansys, import the model and open it in space claim and cut the model

into half so that the academic version support.

Assign symmetry to the face of the wall and edges of the car.

Connection

Then mesh the component with required mesh size in this assignment we will use
Mesh Method

Face Sizing

Analysis setting give the end time as 1e-003, maximum energy error is given as 0.1 to avoid energy error and fix the car body and give displacement to the wall.

Displacement to wall

Assign the parametric to study different cases of thickness of 0.3,0.6 and 0.9mm respective results.

RESULTS
Case 1: Thickness 0.3mm
Total Deformation

Equivalent stress.

Equivalent strain

Directional Deformation 

Conclusion

From the above stimulation results it is clearly concluded that the increase in thickness will reduce the total deformation and reduce the impact.
