Free to use LS-DYNA Finite Element Vehicle Models from NHTSA

Here is how to download and use a selection of free to use finite element vehicle models, developed by NHTSA. These models are extremely well designed and can be a useful learning tool for beginners to LS-DYNA and finite element analysis (FEA) modeling techniques. The model that I will highlight in this video is the Chevy Silverado Truck FEA model. Note, that these models are large and complicated and will be challenging to run on a local computer.
Finite element analysis uses the finite element method to simulate physical events through computational modeling. These models are a perfect example to how finite element models can be used for real-world applications.
The link to the models is below:

7:14 "Look at all of those bolts! That´s just nuts!" YEEES, bolts and nuts usually go well together. My man did a pun without even knowing.

pun intended?

Can you please let me know how can I find a model of a large trucks? I am looking for a model of over-height vehicles/trucks. I hope you can help with that.

[@sabhajeetyadav9726]

Please upload a detailed video of crash simulation

[@nik9643]

Please upload more tutorials regarding cards and problems faced during analysis

May I ask how to put the airbag and dummy into the car

[@adanegashu801]

thanks for this video, if you have more tutorials on LS DYNA please upload specially on impact simulation

[@Evanyali]

May I ask what's the difference between the baseline model and the lightweight model? Is that means model's mass? Thanks.

[@muhammadaffanarif9066]

I want to run a crash analysis of my robot, can you please suggest me if I should first import my robot model assembly from Solidworks to Ansys Spaceclaim, and then export to LS Dyna? And if all the components are OK as Solid? Or else, do I need to change all of the components to shell? Thank you very much for your time.

[@anshulgoswami1275]

please post the link for videos of models on their website which you are talking about, i cant find em

[@ShubhamMishra-ed7mb]

Hi, does anyone know where i can get cad files (sheetmetal, plastic trim parts for vehicles interior ) for meshing practices?

[@UnpopularMechanics]

grabcad.com is a great place to find all kinds of CAD files. I’m sure you can find what you are looking for there.

[@ShubhamMishra-ed7mb]

@@UnpopularMechanics i know that one but I'm not being able to find properly modeled parts, they are mostly modeled for rendering, aesthetics.

[@viveknair0708]

Sir Can u give me the link where I can download free dummy model for our project..I have tried but I didn't get the link

[@dimasbagussetiawan4484]

is it possible to simulate a large deformation analysis ? Such as crash test analysis and evaluate all of the parts in the car. Because there is so much the results in CZcams, but no one thatgive the tutorials out

[@UnpopularMechanics]

Yes it is but the issue is simulating it on a personal computer. It takes quite a lot of resources to simulated a fully deformable vehicle crash

[@dimasbagussetiawan4484]

@@UnpopularMechanics Thank you for replying. Could you teach and share to us about the step to simulate in LS-DYNA ? It is OK and enough just the steps, then the viewers can evaluate their models by themself.

[@jfernan751]

Hi, could you please show how to initialize the calculation and actually run the case?

[@ManuelGarcia-ef1cc]

Hi, thanks for the video.
Is there any form to open this model with SolidWorks?

[@ManuelGarcia-ef1cc]

Which program do you use?

[@TheSundara44]

this is FE model you can use Hypermesh or ANSA or any pre processor tool to open it

[@ashespokhrel1457]

can you do a tutorial to run this simulation?

[@UnpopularMechanics]

I’ll try to get around to this. The issue is that this isn’t a “simulation” per say. It’s a FEA model that you can use in a set of boundary conditions. Meaning if you simulated this it will just sit there and not do anything. You need to define what you want the vehicle to do.

[@srishtibhutani6242]

@@UnpopularMechanics Can you post a tutorial of a vehicle like this running into a rigid wall?

[@z4961]

Dear sir
Thanks for the video.
Do you think it is possible to get a free dummy model to play with ?
