Create tire and wheel in Adams view

Create tire and wheel in Adams view

Create tire and wheel in Adams view

(OP)

I am a beginner of Adams view. I have tried to model tire in Adams view. I came to know it requires a Tire property file ('.tir') and a road property file. I don't know these files are already built-in standard library files or we have to create it ourselves. If it is a standard library file how can I access this file? If not, How could I make myself?

RE: Create tire and wheel in Adams view

There should be a road property file called mdi_2d_flat.rdf lurking somewhere, which is enough to get you going.

Here it is in all its glory

Tire data is a lot harder to get, have a look for C:\Program Files\MSC.Software\Adams\2019_2_2\atire\tires.tbl\pac2002_175_70R13.tir where you may need to change the install directory. That's a Pacejka model so you can modify the coefficients to fit your tire.

If you don't have adams/tire, car or chassis then things start to look a bit awkward. If you want to get into generating your own tir files then https://au.mathworks.com/matlabcentral/fileexchang... is a good place to start.

Failing that random googling leads to various websites that have demo tires.
