The implemented force balance, state definition, sign convention, and model boundary are public.
VehicleLab 1.1.0
Understand suspension response in time and frequency.
Study transient road events or normalized harmonic response, explore one parameter at a time, and compare designs. Visualize motion and export engineering evidence directly in your browser.
Start with Half Car · 4 DOF for coupled heave and pitch, separate axle roads, and synchronized Motion. Quarter Car · 2 DOF remains a simpler reference model. Meet the half-car model

01 / A simpler engineering workflow
Study → Explore → Compare
Three focused workspaces keep one study, bounded design exploration, and detailed comparison separate while preserving one continuous engineering context. A compact Journey map records which capabilities you have completed without judging whether the current edited inputs match retained evidence.
- 01
Study
Understand one configuration under a transient road event or steady harmonic excitation.
- 02
Explore
Sweep one supported physical parameter over an exact candidate range under one scenario.
- 03
Compare
Evaluate Baseline and Variant A in time or on one exact shared frequency grid.
02 / Engineering trust
The assumptions stay visible.
VehicleLab keeps numerical behavior, provenance, equations, validation evidence, and the current model boundary close to the result—not hidden behind a product claim.
Review Verification & Validation evidence →Identical accepted inputs produce identical time bases, channels, metrics, and sweep candidates.
A dedicated Web Worker runs the study. Inputs and results are not sent to a VehicleLab backend.
Canonical regression checks and a source-audited published benchmark remain inspectable.
03 / Product capability
Focused ride-study decisions.
- Four prescribed road inputs and editable physical parameters
- Headline ride metrics and synchronized time-history plots
- Direct complex frequency response for both models
- Baseline/Variant frequency overlays, peak shifts, and native-point inspection
- Deterministic one-parameter sweeps with exact endpoints
- Actual-candidate response and trade-off plots with UTF-8 CSV export
- Baseline versus Variant A deltas, overlays, and shared Model / Vehicle motion
- Definition-only projects, completed-evidence CSV and plot PNG, and one persistent PDF Engineering Report action
- Published Zhao et al. numerical benchmark and visible V&V evidence
04 / Honest model boundary
A deliberately narrow model.
The preset is generic and has not been correlated to a production vehicle. The current linear passive models exclude roll, lateral dynamics, nonlinear components, contact loss, and control systems.
VehicleLab supports transparent engineering exploration. It is not a certification, safety-validation, optimization, or full-vehicle platform.
Read the complete model boundary →05 / Start a study
Move from one response to a defensible comparison.
Start with the generic preset, inspect time or frequency response, explore a bounded range, compare an alternative, and export review-ready engineering evidence. Completed transient Study evidence can also become a publication-ready wide or vertical video.
