I created and pushed to the main branch of the Chrono repository a set of JSON files which define the same toy vehicle as in demo_VEH_ArticulatedVehicle<https://github.com/projectchrono/chrono/tree/main/src/demos/vehicle/articulated_vehicle>. You can see these new files here<https://github.com/projectchrono/chrono/tree/main/data/vehicle/articulated_chassis>. This JSON—specified vehicle model can be used from the C++ demo_VEH_WheeledJSON<https://github.com/projectchrono/chrono/blob/main/src/demos/vehicle/wheeled_models/demo_VEH_WheeledJSON.cpp> or from the Python demo_VEH_WheeledJSON<https://github.com/projectchrono/chrono/blob/main/src/demos/python/vehicle/demo_VEH_WheeledJSON.py> (by uncommenting the appropriate lines). Like the C++ example model, this JSON-based ACV model uses a 2WD driveline connected to the front axle. To use a 4WD driveline, simply create an appropriate JSON specification file (such as this one<https://github.com/projectchrono/chrono/blob/main/data/vehicle/hmmwv/driveline/HMMWV_Driveline4WD.json>) and modify accordingly the vehicle specification JSON file (like done here<https://github.com/projectchrono/chrono/blob/4e6f407dca8fef1a4fbfab124db1c1a8b4f87ae2/data/vehicle/hmmwv/vehicle/HMMWV_Vehicle_4WD.json#L43>).

I have the following questions to ask for help. 1)In demo_VEH_TrailerJSON.py, Some contents about the json files of Sedan and Trailer are as follows， "Name": "Sedan", "Type": "Vehicle", "Template": "WheeledVehicle", "Name": "Ultra Tow 40x48", "Type": "Trailer", "Template": "WheeledTrailer", Is the beginning of the json file of the front body and rear body of the articulated vehicle the same? 2)How to write JSON files to enable four-wheel drive of articulated vehicles? The powerful function of Chrono cannot be separated from the efforts of everyone in the team, and I am very interested in Chrono. But according to the demo_ VEH_ TrailerJSON. Py is still struggling to write json files for articulated vehicle, so do I have any better references? Or does the team intend to write a json file demo for articulated vehicles in the later stage. -- You received this message because you are subscribed to the Google Groups "ProjectChrono" group.
