there is a guidance "Use the Vehicle track parameter to specify the number of tracks'' in mathwork site for vehicle dynamics blockset/vehicle body, but I can't find any options to add an extra axle to vehicle body in simulink using vehicle dynamics blockset, having said that the example,
Three-Axle Tractor Towing a Trailer
use a mid axle but I could'nt change the vehicle body configuration in vehicle dynamics blockset. How can I add an extra axle to the 3 DOF vehicle body?

Hi Aria,
You can add axles and tracks to the Suspension blocks at will, but our Trailer and Vehicle body blocks (whether 3DOF or 6DOF) do not allow the addition of tracks or axles in a flexible manner. We have 2 and 3 axle vehicle bodies, and 2 and 3 axle trailer bodies for both 3DOF and 6DOF cases. Presently we only offer only 2 track configuration for all vehicle and trailer bodies.
Thanks,
Mike

Hello, I saw the Example already, but I want to give Torque unequally to the Trailer model, not to the Truck model, I was wondering if this is ok and if it will simulate correctly or there will be some problems?
I will check the presentation carefully and let you know if I still have questions.
Thanks!

There shouldn't be any restriction on whether or not the axle torque is applied equally to the left and right side of the trailer.
