Week 11 Car Crash simulation
AIM: To perform the Car crash simulation.
PROCEDURE:
- First we will import the given geometry to the ANSYS workbench in Explicit dynamic module.
- For this we are using Stainless Steel NL material.
- Now the model is shown below:
- So here we have to assign the thickness and material to car body. So we are using Stainless Steel Non lineat materila and thickness as 0.3 mm. As shown below:
- Now after this we will mesh the given component.
- Now after this we will fixed the car body and assign the displacement to the wall.
- Now the analysis setting is as follows:
- After this we will add the required results and run the simulation.
CASE 1: Thickness : 0.3 mm
Total Deformation
Equivalent Stress
CASE 2: Thickness : 0.4 mm
Total Deformation
Equivalent Stress
CASE 3: Thickness : 0.5 mm
Total Deformation
Equivalent Stress
| Sr No. | Thickenss(mm) | Total Deformation (mm) | Equivalent Stress (MPa) |
| 1 | 0.3 | 865.47 | 88669 |
| 2 | 0.6 | 836.14 | 45955 |
| 3 | 1 | 870.38 | 38042 |
Result:
- The simulation run successfully and the results are calculated.
- As we see as the thickness increase the equivalent stress here is decreasing.
- Total deformation is also varying as the thickness changes.
