Is it possible to make dynamic friction time-dependent? I need to use a changing dynamic friction coefficient to simulate the behavior of guides that are not lubricated equally.

Its possible. Apply the time-dependent friction function or table to the relevant parts or we can also use python script if yoau are comfortble with that. But its very easy to give function. Example would be create a table in excel and generate a function in excel based on the inputed variable and use that function.
You do not state if this is a joint friction or a contact friction.
The joint friction can only take a scalar value for the friction coefficient. However, when running the analysis using a solver script (or acf-file in the external solver) you can issue commands to change these values. Have a look at the online help for the Adams Solver -> C++ Version of Adams Solver -> C++ Commands.
The contact friction cannot be changed the same way as described above.
To be able to change the contact friction, you will need to use a CFFSUB subroutine to model and change the friction.
If you don't want to use a simulation script, you could also model your joint friction yourself with a force element. This way you specify the function for it yourself, and can thereby change it when needed.
Yes, I have already thought about modeling the friction with a force element. As I have only recently started working with Adams, this is perhaps the simpler version. But I'm also goingt to have a look at the online help for the Adams Solver. Thanks a lot!
