Scenario: four prescribed corner road inputs. Initial conditions and solver settings belong to the scenario.

Planar handling consumes applied lateral tires and yaw inertia (2500 kg m² · generic default). Longitudinal and combined-slip configurations remain inspection only. No dynamic vertical/planar coupling is installed.

Model assumptions and limitations

Passive Full-Car with rigid Double-Wishbone kinematic force mapping: sprung-body heave, pitch and roll plus four independent unsprung vertical motions (7 DOF / 14 interleaved states).
Small pitch/roll increments from the supplied design datum; upward heave, nose-up pitch and left-side-up roll. Body attachments: front z + a*theta, rear z - b*theta, with left + track/2*phi and right - track/2*phi.
Four independent prescribed temporal corner road inputs. They are not a traveling spatial road surface; no spatial-road reconstruction.
Linear installed spring/damper elements and tire stiffness; geometry-dependent passive corner forces. Fixed-heading chassis-forward-projection constraint; no tie rod, steering linkage, true toe/K&C, compliance bushings, chassis flexibility, bump/rebound stops, static preload/gravity ride-height solve or tire contact-loss mechanics.
No lateral dynamics, yaw, longitudinal tire dynamics or active control.
Generic passenger-car preset has no measured-vehicle correlation or production-vehicle validation claim. Independent numerical verification is not physical validation.
Full-Car release 1.19.0 Rig supports Transient Study with completed-evidence Model and Vehicle Motion and Report/data. Rig Engineering Video, Frequency, Explore and Compare remain unavailable.

Model & evidence

Evidence and documentation open in a new tab so this engineering session stays here.

Passive 7-DOF body and four wheel motions with geometry-coupled spring/damper forces. Generic presets are uncorrelated. Evidence covers named cases; it does not certify a custom vehicle.
