14 DOF / 28 states
Follow the whole vehicle.
Run the prepared vehicle with moving-rack steering, suspension and tire forces. Inspect physical motion and qualified smooth-road contact.
Explore the workflow →VehicleLab 2.1.1 / Browser-native engineering
Vehicle dynamics engineering.
In your browser.
From suspension and tire studies to coupled full-vehicle dynamics. Configure a vehicle, run real physics, and connect every motion to engineering evidence.
- Native C++ / WebAssembly
- Browser-local computation
- Physical Motion & engineering plots
- Documented numerical verification
01 / Engineering range
Start with a question.
Choose the right model.
Each workflow has a defined physical scope. Add complexity when the engineering question calls for it.
2 / 4 / 7 DOF
Find the response that matters.
Study body and wheel motion, pitch and roll. Compare Quarter/Half-Car designs or drive a Full-Car Ride model over prescribed road inputs.
Explore the workflow →Geometry & tires
Look inside the mechanism.
Inspect Double-Wishbone and qualified MacPherson geometry, steering, and longitudinal, lateral and combined-slip tire studies.

From the full vehicle to the tie rod.
Vehicle & Road
Configure the assembly and select a procedural surface or supported OpenCRG file. Shared Road identity follows compatible models.
Test & Traversal
Choose prescribed Ride traversal or a prepared coupled-vehicle maneuver. Run explicitly; inspect model-specific limits before interpreting results.
Motion & Evidence
Explore synchronized physical views, response plots and traceable data. Engineering reports and video are available in their supported workflows.
Reproducible by design
Independent numerical references, convergence checks, source identities and completed-result provenance connect the implementation to its stated equations. Native and TypeScript implementations retain explicit identities.
Honest physical boundaries
Numerical verification is not measured-vehicle correlation or safety certification. The 14-DOF Road model uses point contact within a smooth, continuously loaded envelope. It rejects many rough OpenCRG files that prescribed 7-DOF Ride can use.
Read the model and contact limits →Your computation stays local
Run without installing a solver or creating an account. Models and simulation work stay in your browser; explicit exports keep engineering data portable.
Built for engineering conversations
For ride, chassis and vehicle dynamics teams. For researchers who need transparent models. For educators connecting equations to motion.
