- COMPUTE THE IIHS DISPLACEMENT INTRUSIONS OF THE POINT BASED ON THE AVERAGE SEAT MOTION*
Computes the IIHS displacement intrusion of a structural node relative to the average seat motion by differencing the node’s X/Y/Z displacement curves from the corresponding seat reference curves. Use this worker to derive intrusion time-histories for IIHS small-overlap or side-impact evaluations where seat-relative displacement is the relevant metric.

Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Avg Seat X Displacement | avg_seat_x_displacement | vector | — | Time-history curve of the average seat X-axis displacement (mm vs. time); used as the seat reference baseline in the longitudinal direction. Optional — omit if the X component is not needed for the intrusion calculation. | |
| Avg Seat Y Disp | avg_seat_y_disp | vector | — | Time-history curve of the average seat Y-axis displacement (mm vs. time); used as the seat reference baseline in the lateral direction. Optional — omit if the Y component is not needed for the intrusion calculation. | |
| Avg Seat Z Disp | avg_seat_z_disp | vector | — | Time-history curve of the average seat Z-axis displacement (mm vs. time); used as the seat reference baseline in the vertical direction. Optional — omit if the Z component is not needed for the intrusion calculation. | |
| Location X Disp | location_x_disp | vector | — | Time-history curve of the intrusion-point node X-axis displacement (mm vs. time); the seat-relative X intrusion is computed by subtracting the seat X reference curve from this curve. | |
| Location Y Disp | location_y_disp | vector | — | Time-history curve of the intrusion-point node Y-axis displacement (mm vs. time); the seat-relative Y intrusion is computed by subtracting the seat Y reference curve from this curve. | |
| Location Z Disp | location_z_disp | vector | — | Z coordinate curve for the Node <a class=’btn btn-xs btn-default’ target=’_blank’ href=’https://www.d3view.com/docs/master/workflows/Glossary.html#curveinput’> <i class=’fa fa-external-link’> </i> View more </a> | |
| Location Type | location_type | scalar | lower-hinge | Node Location | |
| Intrusion Type | intrusion_type | scalar | raw |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curves_iihsintrusion_disp_output_1 | curves_iihsintrusion_disp_output_1 | vector | Resulting IIHS intrusion displacement time-history curve (mm vs. time) for the specified node location, expressed relative to the average seat motion; the scalar component or resultant returned depends on the return_type argument supplied to the transformer. |
