HPM – Oasys H-Point Machine

A JavaScript tool for prediction of the H-Point of a seat,
based on the SAE J826 regulation, used in conjunction
with Oasys PRIMER and Ansys LS-DYNA.


The Oasys HPM Positioning Tool provides an interactive
environment to set-up and analyse the positioning of the
H-Point Machine (HPM) in a seat.
All pre-simulation positioning of the HPM is completed
automatically within Oasys PRIMER and the output is
a ready-to-run LS-DYNA model. Once the analysis is
completed, Oasys PRIMER is used for interpretation of
the results to report the H-point co-ordinates and back
angle of the HPM.

Crash Prediction Accuracy

Using the Oasys HPM positioning tool gives seat
engineers confidence in the H-Point of a new seat
design and allows them an opportunity to adjust the
design if necessary.
This improved understanding of the seat will allow more
accurate predictions of whiplash performance and other
crash test simulations where dummy positioning
is critical.
