VehicleLab 1.19.0
This release adds Suspension Engineering Comparison for physically steered Double Wishbone and MacPherson Strut. Shared physical-spindle camber, signed toe and motion ratios, geometric caster/SAI references and independent metric verification support common-input studies. Advanced geometry editing, honest rejected ranges and synchronized solved inspection accompany CSV, provenance JSON and searchable Engineering Report downloads from one completed snapshot. Comparison remains separate from Project Save/Open and passive Full-Car forces. MacPherson Full-Car dynamics, nonlinear tires, steering forces and coupled handling remain future work.
A persistent contextual Studio workspace starts with Suspension Kinematics, Vehicle Ride Simulation or Road Definition & Traversal. New, Open, Save and Export stay prominent; supported local definitions download from Save, and edited work requires confirmation before replacement. Full-Car temporal and spatial Vehicle views share viewport controls and a Suspension camera that follows the selected solved corner. Existing physics, numerical validation and the independent 1.13.0 suspension evidence are retained.
Independent Double-Wishbone verificationchecks compatible planar mechanisms against an analytical reference. Suspension views share spring seats and a translucent damper housing with a piston driven by solved endpoints. The model importer now offers a consistent drop area, file chooser and STL alignment guidance.
Full-Car uses a cleaner generic sedan with one See-through body control. Import 3D Model stages local GLB/STL exterior meshes with units, axes, uniform alignment and component exclusions. Session bodies are shared by Motion and supported spatial video; they never configure physical parameters or suspension hardpoints.
Double-Wishbone hardpoint geometry now determines spring/damper motion and passive Full-Car suspension forces while retaining the 7-DOF architecture. Results articulates the same completed suspension definition used by the simulation.
Full Car · 7 DOF supports Transient Study with body heave, pitch, roll and either four prescribed temporal corner inputs, a procedural spatial road, or a locally imported ASAM OpenCRG road from the supported subset, with straight constant-speed traversal. Completed-evidence Drive over Road Motion moves the vehicle over a stationary road with five cameras. All sources export complete engineering data, plots, provenance and reports; project.v1 save remains available for Rig only. Full-Car Spatial Engineering Video is available; Rig video, Frequency, Explore and Compare remain unavailable.
Half Car · 4 DOF is the initial Studio model, with coupled heave and pitch, explicit front and rear axle roads, and separate front and rear suspension parameters. Quarter Car · 2 DOF remains a simpler reference model. Both support Transient and Frequency Study and Compare plus Transient Explore.
Transient Study and Compare can show a Model schematic or contextual 3D Vehicle Motion. Quarter/Half-Car completed Transient Study can export a local wide or vertical engineering video. Motion uses completed numerical evidence; mirrored wheels and local axle roads are visual context, not independent corners or a reconstructed spatial road.
Study, Explore, and Compare share a clear engineering path. Deterministic runs produce completed evidence for interpretation, exact-channel CSV, per-plot PNG, and one persistent Engineering Report action. Portable projects store definitions only; importing one requires a new run. Journey remembers explored capabilities separately from engineering and project state. The public V&V evidence includes one source-audited quarter-car numerical benchmark; it does not establish measured production-vehicle correlation.
