COMPUTE THE OCCUPANT LOAD CRITERIA FROM A GIVEN VEHICLE VELOCITY¶
Computes the Occupant Load Criteria (OLC) in PSI units from a vehicle velocity time history. The OLC is derived by integrating the velocity curve over a specified displacement window and applying an optional acceleration scale factor. Use this worker to evaluate occupant loading severity in crash pulse analyses.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curve | vehicle_velocity | vector | — | Vehicle velocity time history curve (time vs. velocity, e.g. in mm/ms or m/s) used as the basis for OLC computation; must be supplied as a vector/curve object. | |
| Min Disp | min_disp | scalar | 65 | Lower bound of the displacement integration window in mm (default 65 mm); defines the start of the OLC evaluation range. | |
| Max Disp | max_disp | scalar | 300 | Upper bound of the displacement integration window in mm (default 300 mm); defines the end of the OLC evaluation range. | |
| Scale Factor | scale_factor | number | 1 | Multiplicative scale factor applied to the derived acceleration signal before OLC calculation (default 1.0; adjust to convert units or normalise the input curve). |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_olc_psi_output_1 | curve_olc_psi_output_1 | scalar | Scalar OLC value in PSI (g-equivalent occupant deceleration) computed over the specified displacement window from the input vehicle velocity curve. |
