crash box simulation

aim:

to simulate the crash test and plot result.

procedure:

for thickness 1.2 mm

1. import the given model and create the material for the component in keyword manager.

2. create the section id for the material in key word manager wtih tickness 1.2mm

3. assign the material and section for the model by choosing part in keyword

4. create the rigid wall for the model by choosing rigid wall planar in entities

5. create the initial velocity for the model by intial velocity in entities area.

6. create the contact for the model by choosing automatic single surface in key word manager and also give master and slave for the contact.

7. create the ascii values , cross section set , binary d3 plot and history node in database.

for thickness 1.5 mm follow the same procedure by changing 1.2 to 1.5 tickness in section and run the simulation.

conclusion:

for 1.2 mm thickness the out put results

cross section force:

acceleration:

energy:

for 1.5mm thickness

cross section force:

acceleration

energy:

from the above result the resistance will be higher when the thickness is increased from 1.2 to 1.5 thickness.

result :

thus the result are been ploted and simulation is runned for the given mesh.
