You didn’t explore all available options and demos carefully enough 😊.
Chrono::Vehicle provides a kinematic driveline model for an arbitrary number of driven axles (see ChSimpleDrivelineXWD<https://api.projectchrono.org/classchrono_1_1vehicle_1_1_ch_simple_driveline_x_w_d.html>) as well as a shafts-based 6x6 and 8x8 drivelines (see ChShaftsDriveline6WD <https://api.projectchrono.org/classchrono_1_1vehicle_1_1_ch_shafts_driveline6_w_d.html> and ChShaftsDriveline8WD<https://api.projectchrono.org/classchrono_1_1vehicle_1_1_ch_shafts_driveline8_w_d.html>). There are 3 wheeled vehicle models available that use that: * The 7t MAN<https://github.com/projectchrono/chrono/tree/main/src/chrono_models/vehicle/man> truck model has an option for using a 6x6 driveline (derived from ChSimpleDrivelineXWD) * The 10t MAN truck model has an option for using an 8x8 driveline (derived from ChSimpleDrivelineXWD) * The MROLE<https://github.com/projectchrono/chrono/tree/main/src/chrono_models/vehicle/mrole> model can be configured to use 2x2, 4x4, 6x6, or 8x8 drivelines (derived from ChSimpleDrivelineXWD or from ChShaftsDriveline8WD If you are interested in JSON-based specification of vehicles with more than 2 driven axles, look at the vehicle and driveline JSON files for the MAN trucks<https://github.com/projectchrono/chrono/tree/main/data/vehicle/MAN_Kat1>. You can select any of the above models in: * demo_VEH_Wheeled<https://github.com/projectchrono/chrono/blob/main/src/demos/vehicle/wheeled_models/demo_VEH_Wheeled.cpp> (using the C++ vehicle models) * demo_VEH_WheeledJSON<https://github.com/projectchrono/chrono/blob/main/src/demos/vehicle/wheeled_models/demo_VEH_WheeledJSON.cpp> (using JSON-based vehicle model specifications) Best, Radu From: [email protected] <[email protected]> On Behalf Of osman cankurtaran Sent: Friday, March 21, 2025 11:47 AM To: ProjectChrono <[email protected]> Subject: [chrono] Is it possible to model a 6x6 or 8x8 vehicle chassis in Chrono? Hi everyone, I’ve been exploring Project Chrono for off-road vehicle simulation, and I’m currently working on a concept that involves a multi-axle chassis — specifically a 6x6 or even an 8x8 configuration. I’ve seen various examples of 4x4 setups and tracked vehicles, but I was wondering: * Is it currently possible to model and simulate a 6x6 or 8x8 wheeled vehicle in Chrono? * If so, are there any recommended modules, examples, or best practices to follow for such configurations? * Are there limitations or challenges I should be aware of when extending the number of axles? Any guidance or reference to similar projects would be greatly appreciated! Thanks in advance, -- You received this message because you are subscribed to the Google Groups "ProjectChrono" group.
