COMPUTE THE OCCUPANT INJURY STAR-RATING BASED ON THE DATASET WITH VALUES FOR HICD AND PEAK VALUE SOF CHEST, FEMUR AND NECK VALUES¶
Computes the occupant injury star rating (NCAP-style) from a dataset containing HICd, peak chest deflection, peak femur load, and peak neck injury values (NIJ, tension, compression). Use this worker to translate raw injury-criterion scalars into a standardised star rating for frontal-impact occupant safety assessments.
When to use¶
Classification: process.
Tagged: HICd, NCAP, chest_deflection, dataset, femur_load, injury_criteria, neck_NIJ, neck_compression.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Dataset | dataset | dataset | — | Input dataset (tabular) containing one or more rows of occupant injury metric values — must include columns referenced by the scalar inputs below; leave unconnected only if all scalar values are supplied as literals. | |
| New Column Name | new_colname | text | — | Name of the new column that will hold the computed star-rating values appended to the output dataset; defaults to a generated name if left blank. | |
| HICd | hi_cd | scalar | — | HICd (Head Injury Criterion — dummy) value, dimensionless; select the corresponding dataset column or supply a numeric literal — used as the head injury input to the star-rating algorithm. | |
| Peak Chest Deflection in mm | peak_chest_deflectioninmm | scalar | — | Peak chest deflection in millimetres (mm); select the corresponding dataset column or supply a numeric literal — represents thorax injury severity. | |
| Peak Femur Load in kN | peak_femur_loadink_n | scalar | — | Peak femur compressive load in kilonewtons (kN); select the corresponding dataset column or supply a numeric literal — represents lower-extremity injury risk. | |
| Peak Neck NIJ in kN | peak_neck_ni_jink_n | scalar | — | Peak neck NIJ (Neck Injury Criterion) value in kN; select the corresponding dataset column or supply a numeric literal — combined tension/shear neck injury metric. | |
| Peak Neck Tension in kN | peak_neck_tensionink_n | scalar | — | Peak neck tension force in kilonewtons (kN); select the corresponding dataset column or supply a numeric literal — used alongside NIJ and compression for neck injury assessment. | |
| Peak Neck Compression in kN | peak_neck_compressionink_n | scalar | — | ||
| Occupant Type | occupant_type | string | H3-5 | Occupant dummy type string (e.g. ‘driver’, ‘passenger’, ‘Hybrid III 50th’) that governs which regulatory thresholds are applied in the star-rating algorithm. | |
| Unit System | unit_system | string | mm-kN-ms | Unit system identifier (e.g. ‘SI’, ‘US’) that controls internal unit conversions applied before threshold comparisons; must match the units of the supplied scalar inputs. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| dataset_compute_star_rating_output_1 | dataset_compute_star_rating_output_1 | dataset | Augmented dataset identical to the input dataset with one additional column (named by new_colname) containing the computed integer star rating (0–5) for each row. |
