The science · model notes

Tyre traction · friction circle

√(Fx² + Fy²) ≤ μ Fz. Each of four tyres shares a normal load; combined cornering and drive/brake demand cannot exceed its grip budget.

Grade acceleration

a = μg cos(θ) − g sin(θ) at the traction limit. Rolling resistance and aerodynamic drag are added in the time-step model.

Suspension & stability

ωₙ = √(k/m), T = 2π√(m/k). Static side-tip estimate: θtip = atan(b / hCG), with track half-width b = 1.12 m.

Braking overlay

d = v² / (2 μ g), assuming a level surface, constant grip and full braking. Actual stopping distance on the grade can be longer.

Assumptions

Planar rigid-body chassis with estimated roll/pitch response, four independent Coulomb friction circles, procedural spring-damper travel, simplified torque curve and hydraulic energy. No full multibody solver, tyre relaxation, granular compaction, or certified rollover calculation.

Not run

Educational engineering sandbox only — not an operator-training device. Primitive PBR geometry; GLB placeholders are listed in machine_rig.json. High quality default · add ?q=low for lower GPU load.
