Car crash simulation

Simulation Resistance of materials

Hello

I want to run a crash test simulation of an automotive chassis part on solidworks. I performed a dynamic nonlinear simulation. However, my knowledge of crashes being limited, I would like to know if dynamic nonlinear analysis is the most suitable for this kind of simulation.

About my simulation: profile recessed on a wall; application of a force on the opposite wall (in compression); Duration: 10ms.

Thank you

Florent

Hello FlorentPT

We answered you on December 20
https://www.lynkoa.com/forum/solidworks-simulation/echec-du-solveur-simulation-compression-statique

by giving you a precise indication that I summarize here:

The premium simulation module (non-PRO) only performs simulations in the elastic domain, which means that SW simulation never goes into the plastic domain.

So you won't be able to carry out the desired simulation.

I would add that the simulation software that allows you to do what you want is not accessible because only car manufacturers or their first-tier suppliers can have access to it (given the astronomical price and the very powerful machines to use them.

I see that Santa Claus didn't put the right software in your shoes and that's probably heartbreaking :-)

Kind regards

A misunderstanding of the SW doc had made me think that nonlinear analysis with large deformations corrected it ...

Thank you for your help

Kind regards

Florent I don't know if you'll have a chance to read that message. I don't think it's a misinterpretation on your part: at most a lack of attention on the page that specifies the field of use of simulation, namely the elastic domain for SW simulation To answer this question of long trips, I have created a short tutorial for you. It also shows that you can push the deformation very far if you use a particular design. In a way, this is what car manufacturers are looking for, which is a progressive deformation of the passenger compartment, except that they use both the elastic and the plastic domain.
