I am building a truck dragging a trailer model using simscape. As for building a truck (tractor) I can use the vehicle body blovk and define the parameters but now I need to attach a trailer to the model. How can it be done? do I need to use again a vehicle body block for defining a trailer and attach it to the truck's vehicle body at the H coonnection port? Will this simscape model resembel to the truck and trailer physical model.

I want to build a vehicle body model in simscape using the driveline library. My objective is to build a tractor with a trailer (a reference image attached from google). Using simscape I can simply build the tractor and run it by giving torque input. (Image attached for a 4x2 and optional 6X4 drive simscape model). Now like a real physical application I want to attach a trailer to this and run the whole vehicle in longitudinal direction. The trailer susbsystem attached in the end is the

one I am trying to figure out. Screenshot 2019-07-30 at 10.28.17 PM.png

Hello Rahul,

Did you figure out how to attach the trailer to the vehicle body. Because I have the same question.

Rahul,

I see this is an old thread, but I at least wanted to let you know there are some additional capabilities since you posted your question. There is a tractor towing a trailer demo in the Vehicle Dynamics Blockset. Simscape Multibody is a much more general purpose tool that can model just about any system you can think of, but if you just want a pre-built tractor / trailer model, the Vehicle Dynamics Blockset may provide an alternative starting point for you.
