Hyundai Motor Company virtually tests
for seat vibrations early in the development
process thanks to ESI's Virtual Seat Solution
Improving the comfort of vehicle occupant
Paris, France - June 27, 2013 - ESI Group, pioneer and world-leading solution
provider in virtual prototyping for manufacturing industries, announces that
Hyundai Motor Company has extended its usage of Virtual Seat Solution to dynamic
comfort testing, in order to assess and improve the vibratory comfort of their
car seats.
Reducing seat vibrations greatly contributes to improving a seat's overall
dynamic comfort, by protecting the occupant from muscular fatigue; an important
issue for long journeys and with possible long-term effects on the spine. Han Ji
Won, Engineer, Body & Trim development team at Hyundai Motor Company, declares,
"Since seats contain lots of components, it's very difficult to find the factors
that influence the dynamic comfort of the seat. We tried to figure this out
using ESI's Virtual Seat Solution and reached our goal. This new way of working
will help us save money and time effectively."
ESI's end-to-end Virtual Seat Solution, dedicated to the virtual manufacturing,
testing and optimization of seats, has been used by Hyundai for many years to
conduct virtual tests in several seat performance domains; including seating
posture and body pressure and foam hardness. Recently, Hyundai's Body & Trim
development team sought to extend their usage of Virtual Seat Solution to
evaluate dynamic comfort.
Traditionally, carmakers assess seat vibrations by asking volunteers to provide
feedback on vibrations they experience; a method that delivers highly subjective
results and has poor repeatability for many reasons, including the change of
volunteer morphology with time. In an effort to overcome these drawbacks,
Hyundai engineers started by developing and calibrating a new dynamic dummy
model dedicated to vibratory tests.
With ESI's Virtual Seat Solution, Hyundai engineers now use their dynamic dummy
model to perform complete virtual dynamic tests of an occupied seat. The first
step is to simulate the dummy sitting in the seat. This step is mandatory as it
allows determination of the non-uniform compression of the foam in cushions of
the occupied seat.

The second step is to simulate the vibrations test with the seated dummy to
obtain the transfer function that describes the capacity of the seat to absorb
the vibrations. To achieve good correlation with real testing it is essential
that the seat model - in particular the foam - inherits the correct properties
from both the seat fabrication and dummy seating by "chaining" simulations of
each step in the complete process.
Thanks to this fully validated dummy model, Hyundai performs virtual dynamic
comfort testing with ESI's Virtual Seat Solution earlier in the development
process and can better arrive at the right seat design. The virtual vibration
test is accurate and partly replaces real prototypes, thus allowing the car
manufacturer to develop more comfortable seat designs in less time and at less
cost. Virtual Seat Solution also saves time and increases efficiency by using a
single core model of the seat to support evaluation of several seat performance
domains and to enable design team collaboration.
