Automating HPM Setup and Analysis in Oasys PRIMER
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..

Streamline Seat Design with the Oasys HRMD Positioning Tool
The Oasys HRMD Positioning Tool provides an
interactive environment to set-up and analyse the
positioning of the H-Point Machine in a seat and to
assess the head restraint scoring.
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.
Quick-Check Your Seat Design with Automated Scoring Tools
The HRMD tool takes the static assessment
measurements according to the procedures above
and calculates the test scoring. A quick-check feature
is also provided to make the measurements using a
user-defined H-Point.
