Week 11 Car Crash simulation
Week 11: Car Crash simulation
Aim: Simulating car crash for the given model in Ansys Workbench.
Procedure:
Intially the Explicit Dynamics system is loaded in workbench.
Engineering materials used for this model:
The model imported to Geometry by RMB on geometry -> import -> car.stp
- After importing model, the model is updated to model and the next model, setup and solution is done in mechanical modeler.
Here, meshing, contacts, boundary condition setup, and solution output request are given for analysis.
Meshing:
Analysis Settings:
End time is taken as 0.001s
Boundary Conditions:
Displacement is applied on wall: 500mm
Fixed support applied on back of car where crash possibility is zero:
- Solution output request
After setting the boundary conditions, the soultion outputs as requested is included from
Only for Case 1:
solution -> insert -> Stress -> equivalent von mises
solution -> insert -> Deformation -> Total deformation
Results:
The solving is taken place and can be checked from
The results are taken for Stress and deformation for both cases
Equivalent stress:
Case 1:
Total deformation:
Case 1:
Data From Parametric study
Comparison of Equivalent stress and directional deformation for both cases:
| Car body thickness | Max Equivalent Stress, MPa | max Total Deformation , mm |
| 0.3mm | 11790 | 1035.3 |
| 0.4mm | 11824 | 14885 |
| 0.5mm | 11754 | 8589.5 |
Conclusion:
Simulation of car crash on the given model is successfully simulated using ANSYS WORKBENCH.
