PFC5 Wheel-Tracking and Rutting Test
Use this skill after specimen generation and Burger calibration. Prefer PFC3D because wheel width, lateral confinement, contact patch and rut geometry are intrinsically three-dimensional.
When to use
- plan a wheel-tracking/rutting model in PFC 5.0;
- choose a moving, rolling-faceted or fixed equivalent cyclic load;
- servo a wall/head to a target reaction rather than assign a read-only contact force;
- extract rut-depth histories and an edition-specific dynamic-stability metric;
- scale an RVE to a strip/pilot and then a full-size slab.
- study braking/acceleration with vertical-horizontal coupled loading, asymmetric deformation, particle migration or shear-stress depth profiles;
- audit an equivalent fixed patch or accelerated-time route against an unaccelerated moving-load pilot.
Do not use this skill for Marshall or for specimen generation.
Required inputs
- exact PFC3D 5.0 build, units and runtime budget;
- governing standard edition, method ID, clauses and machine/specimen coefficients;
- slab, mold, wheel and travel geometry;
- conditioning/test temperature;
- wheel motion definition and whether “count” means one-way pass or complete cycle;
- physical load waveform/frequency/rest history and every step used to replace it with a moving, cyclic or constant equivalent route;
- prescribed pressure/load and the physical/equivalent contact-area definition;
- vertical and horizontal load-control implementation, coordinate/sign convention, target vector-reaction ratio and tolerances;
- source and meaning of any
F_h/F_vor friction-demand factor, kept separate from wheel-contact and material-contact friction coefficients; - lateral/front/back boundary conditions and the planned free-versus-confined sensitivity comparison;
- load-ready specimen plus calibrated contact parameters;
- rut-depth measurement region/reference and stop condition;
- laboratory rut curve/dynamic-stability targets.
The current reviewed route is JTG 3410-2025 T 0719-2025, effective 2025-10-01. JTG E20-2011 T0719 is a legacy route and must not supply current default dimensions, time windows or coefficients.
Modeling hierarchy
- RVE/material check — calibrate creep/recovery and timestep sensitivity.
- Strip/pilot model — verify boundaries, contact patch, load servo, wheel motion, rut measurement and computational cost.
- Full-size model — use only after the first two gates pass.
The exact dimensions and test values come from the selected standard edition or laboratory protocol, not from a remembered default.
Loading routes
| Route | Meaning | Acceptance gate |
|---|---|---|
| moving faceted wheel/head | translation over slab | reaction and footprint match target throughout travel |
| rolling faceted wheel | translation plus angular velocity | kinematic sign, slip and facet-resolution sensitivity |
| fixed wall with facet conveyor | fictitious surface conveyance without moving facets | label as conveyor surrogate; validate against moving/rolling footprint and reaction |
| fixed equivalent cyclic patch | accelerated surrogate | correlation to moving-wheel pilot; never label as normative motion |
| fixed equivalent constant patch | creep-oriented accelerated surrogate | preserve declared impulse/dwell or constitutive invariants and pass an unaccelerated comparison |
| vertical-horizontal coupled head | intersection braking/acceleration surrogate | both reaction components, slip/work, direction reversal and boundary sensitivity pass |
In PFC5, contact force is normally an observed reaction. Apply load by a verified servo or velocity/position control and demonstrate that the reaction meets the target. Pressure-to-force conversion requires a declared reference area; the evolving DEM contact area is not automatically that area.
Workflow
- Freeze standard edition, physical parameters and numerical equivalents separately.
- Restore the load-ready specimen, audit boundaries/contact groups and equilibrate.
- Build and motion-test the wheel/head with no specimen.
For a rolling wall, PFC5 translational velocity and angular
spinare different attributes; set the center of rotation on the wheel axis and verify|v| = |omega| Rplus the sign at the contact point. The default rotation center is the global origin, so relying on it is unsafe for an offset wheel. - Run a small contact/load-servo probe; quantify reaction error and oscillation.
- Run the strip pilot for a short declared number of cycles/passes.
- Establish a vertical-only baseline. For an intersection route, add positive and negative horizontal cases and verify both reaction components before interpreting asymmetric deformation.
- Record wheel position, commanded motion, vertical/horizontal reactions, reference surface, rut depth, the seven fixed-position measurements or an approved equivalent, timestep, equilibrium/inertia indicators, one-way pass count and round-trip count.
- If time is compressed, compare
lambda=1and every candidate scale on a small model; audit rut, recovery, contact state and energy, not only the final displacement. - For coupled loading, export forward/reverse-face deformation, lateral heave, phase-separated particle displacement and a tensor-defined shear-depth profile.
- Confirm no wall penetration, particle escape, axis/sign error or callback duplication.
- Run the production duration with restart saves.
- Compute the standard metric only from the selected edition's formula, intervals and coefficients; otherwise report the raw rut history with the metric pending.
- Compare against laboratory curves and run seed/resolution/rate/load-route, contact-mixture, thickness and boundary sensitivity.
Working rules
- Keep PFC5 command/FISH syntax version-pure.
- Do not set
wall.forceas if it were a prescribed actuator without proof from the exact PFC5 API; use a verified motion/servo controller. - Do not assume a rectangular patch, accelerated cycle or fixed load is equivalent to a moving rubber wheel. Calibrate and label the surrogate.
- Do not call translation-only motion “rolling.” A rolling wall needs verified spin, axis/center of rotation and no-slip sign; a facet conveyor is another distinct surrogate because it changes contact relative velocity without moving the facets.
- Do not call a fixed constant patch a dynamic load merely because its duration came from a wheel-pass calculation. State which physical quantities the mapping preserves and which it discards.
F_h = mu F_vmay define an external braking/acceleration demand, but thatmuis not automatically a DEM contact friction coefficient. Verify commanded and measured vector reactions, slip and work independently.- A free horizontal outlet can exaggerate material migration; a fully fixed boundary can suppress it. Report at least one free/confined sensitivity pair before field interpretation.
- A measure-region “shear stress” is incomplete without tensor component, axes, sign, radius/volume weighting, overlap, sample time and empty-region handling.
- Published strip dimensions, load levels, contact fractions, friction-demand factors
and
lambdavalues are case evidence, not package defaults. - For T 0719-2025, compute DS from the current method's pass-count interval and width
coefficient. Do not use the legacy
45 min/60 minshorthand or an unverified extra correction coefficient. - Preserve RVE, strip, pre-load, pilot and production milestone saves.
- Full-size output without pilot load-control evidence is not validated.
Output contract
- PFC build/units and standard edition/method/clause;
- physical versus DEM-equivalent parameter table;
- specimen/wheel/boundary/contact assignment;
- actuator/servo pseudocode or PFC5-verified code plus reaction-error history;
- physical-to-DEM load/time equivalence ledger and accelerated-versus-unaccelerated comparison;
- rut-depth measurement definition and raw time/pass/cycle history;
- vertical/horizontal command and reaction histories, face-asymmetry/lateral-heave metrics, particle displacement fields and tensor-defined shear-depth profiles;
- edition-correct metric calculation with units/coefficients, or pending status;
- RVE/strip/full-size stage evidence and sensitivity results;
- laboratory comparison and
runtime_validatedstatus.
