It is possible to simulate advanced kinematics of tugger train (corner cutting) ?

Hi,

Is it actually possible in FlexSim to simulate realistic tugger train kinematics where carts cut corners on AGV curves (off-tracking), rather than all trailers following the first AGV ?

I couldn't find clear tutorials or threads on this specific behavior online.

I gonna upload the project file but I took it from another ticket.

I built a simple proof-of-concept model about this for a truck pulling a trailer. In the PreDraw trigger of the truck the coordinates of three locations are determined: The connection point on the truck, the connection point on the trailer and the pivot point of the trailer (center of axles). The trailer is rotated around the pivot so that all three points are on a line and then the trailer position is adjusted so that its connection point is at the same coordinates as the truck's connection point. You can chain this logic to accomodate multiple trailers/waggons/carts. For this to work the trailers must not be attached by the AGV system though. You would have to manually manage coupling and uncoupling of carts.

Thanks for help ! I made a simply model based on your truck-trailer. I have a problem with second trolley. It making the same moves like the first one:

Unfortunnelly I don't know what I doing wrong here. Any ideas?

Thanks in advance

@mbojdol .

Is is possible. But you should make it something using process flow or combiner object.
The vehicle has tugger as container pallet which you draw. And the tuggers are curved image like captured by default AGV feature. And you should pick up (loaded) the items on the containers pallet (tuggers) separetely by each container tugger.

You are using the function to lock the trailer to a fixed angle (msgparam1 == 2, msgparam2 == angle). Just remove the respective sendmessage() command.

Thanks everyone it works! I'm going to share a project containing 6 trailers here in case it helps anyone out.

Appreciate the support!
