COMPUTE THE OLC FROM A GIVEN VEHICLE VELOCITY CURVE¶
Computes the Occupant Load Criterion (OLC) scalar value from a vehicle velocity time-history curve. The OLC is derived by integrating the velocity curve over a specified displacement window and applying an optional acceleration scale factor. Use this worker whenever a single OLC number is needed as a crash-pulse severity metric.
When to use¶
Classification: process.
Tagged: crash_pulse, displacement_window, occupant_load_criterion, olc, severity_metric, velocity.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curve | vehicle_velocity | vector | — | Vehicle velocity time-history curve (time in ms, velocity in mm/ms or m/s) used as the source signal for OLC integration; must cover the full crash event. | |
| Min Disp | min_disp | scalar | 65 | Lower bound of the displacement integration window in mm (default 65 mm); defines where OLC evaluation begins along the crush axis. | |
| Max Disp | max_disp | scalar | 300 | Upper bound of the displacement integration window in mm (default 300 mm); defines where OLC evaluation ends along the crush axis. | |
| Scale Factor | scale_factor | number | 1 | Multiplicative scale factor applied to the acceleration derived from the velocity curve (default 1.0); use values other than 1.0 only when unit conversion or signal correction is required. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_olc_number_output_1 | curve_olc_number_output_1 | scalar | Computed OLC scalar value (in g) representing the occupant load criterion over the specified displacement window. |
