has onyone personalized a tractor semitrailer assembly model in Adams/car to carry out a particular simulation?

Hi,

I modified the dafault assembly of tractor semitrailer in Adams/car Truck shared database to perform an analysis. In particular I created two new templates and related subsystems and adding them to the assembly. In spite of previuos runs, where I defined two temlates with same "major rules", this time the assembly compiler doesn't show any error about missing or incorrect input/output communicators. So I don't really have idea why the simulation doesn't work. I tried a straight-line maintain with "quasi-static straight-line setup" flagged and unflagged, but the error is still appearing.

Does anyone have any ideas?

Thank you all

Hi Federico,

I wonder if all the communicators of the templates you created are correctly matched to another communicator in the other template/s and none of them are "hanging" on their own (have you tested them?).

I assume the subsystem/s make sense graphically and I wonder if your vehicle achieves equilibrium??

What is the actual error it generates, can you share it, please?

Thanks,

After you run your simulation and it fails, use the event builder to open the event xml file. In there you change your static to "none" and then press "Save and Run". See if this works better. It often hangs on static due to wrong preload in your airbags or springs. With this method, you usually get at least a few dynamic timesteps out and that will help you debug your model.

Hi Alexis, Hi JSlatten,

thank you for your advices. There was a communicator not correctly matched. Now the simulation can run. If something strange will occur I'll write you…. Thank you.
