unknown error
(OP)
I am trying to model a scaled model for a tractor semi-trailer on MSC ADAMS car, in addition I have the same model in reality and I moved it and record the 6 degrees of freedom.
I will then compare between my experimental model (the real one) and the simulation model to validate the simulation model.
After the validation I will connect this model with a control system (co-simulation) with Simulink model.
I divided the tractor to seven sub-systems (front wheels, rear wheel first axle, rear wheel second axle, chassis rigid body, front steering, front suspension, rear suspension)
I didn’t model the semi-trailer yet as I need to see if the tractor will be successful, then I will model the trailer.
I change all the property files for the springs, dampers, bushing, tire model to be as same as the scaled data.
I test each system separately on ADAMS view and it didn’t give me any error
When I combine all of them together as a full vehicle assembly, then single lane change it gives me error.
I tried to see what is wrong but I couldn’t understand my fault.
I attached a folder contains everything of my model.
I hope you can help me to understand what is my fault.

RE: unknown error
---- START: ERROR ----
Static equilibrium analysis has not been successful.
The maximum number of iterations 75, has been reached.
For the last attempted iteration:
The equation with the largest error was model.tractor_rigid_chassis_modified_weight.ges_frame Comp = 8 Error = 417.483580
The variable receiving the largest increment was model.tractor_rear_suspension_modified_weight.small_lever_to_first_axle Comp = 4 Delta = 2098.154358.

I don't know what is wrong with the frame and tire.
I wish this helps you in assessing my error
