Week 11 Car Crash simulation
Week 11 Car Crash simulation
AIM
To run the Explicit dynamics analysis for Mechanism Car Crash simulation on a total of 3 different cases with change in thickness condition terms and provide the inference on the output.
Objective
To find and compare the results of Equivalent stress, directional deformation, Equivalent elastic strain in all cases.
For this challenge, you will have to perform a parametric study using 3 different values of thickness for the car body. You need to apply the same conditions as mentioned in the video that corresponds to this challenge.Analyse the total deformation and Equivalent stresses acting on the model.
CASE 1 3MM thickness
CASE 2 4MM thickness
CASE 3 5MM thickness
In all cases thickness can be varry
CASE 1 3MM thickness
Import the model.
select the material.
structural steel for wall
And strainless steel NL for car body.
Also add thickness to it as 3MM
Mesh the component with mesh option.
Use method option for 2d is trianglar
Use method option for 3d is tetrahedral
And make face sizing of 200mm
Analysis setting
End time step = 1e-2
fixed support
displacement
z = 500
Use symmentry
CASE 1
Thickness of 4mm
Import the model.
select the material.
structural steel for wall
And strainless steel NL for car body.
Also add thickness to it as 4MM
Mesh the component with mesh option.
Use method option for 2d is trianglar
Use method option for 3d is tetrahedral
And make face sizing of 200mm
Analysis setting
End time step = 1e-2
fixed support
displacement
z = 500
Use symmentry
CASE 1
Thickness of 5mm
