• 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.

When to use

Classification: process.

Tagged: crash, displacement, iihs, intrusion, relative_displacement, seat_motion, side_impact, small_overlap.

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>

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.
