CAE
is one of
the most important
competencies
which enables
our virtual
engineering
environment
and leverages
design and
engineering
process.
Our well established
CAE procedure
and standard
already has
been proved
its effectiveness
by being successfully
applied to
several vehicle
development
programs.
Our state-of-art
computer infrastructure
of super computers
for CAE gives
us just twenty
hours turn-around-time
for full dynamic
side impact
simulation
which is most
CPU intensive
crash analysis.
|
 |
|
We
are using many kinds
of commercial software
packages such as
Dyna3d, NASTRAN,
Marcs, Moldex, Adams-Car,
Fluent, HyperMesh,
Patran and Ideas
MS to cover whole
spectrum of engineering
aspects such as
crashworthiness,
NVH, ride &
handling, head &
fluid analysis and
stiffness &
durability analysis
in systematic way. |
|
|
|
| |
 |
| |
During
the whole stage of vehicle
development from platform
concept development up
to the final production,
crashworthiness and safety
related simulation support
is the most essential
and important. To develop
the structure fully complying
with diversified regulatory
and non-regulatory requirements,
CAE technology leading
structural development
discipline should be established.
In this sense, V-ENS is
fully prepared and our
excellent hardware &
software infrastructure
and human resource enables
all of these. |

Defrost
pattern, temp. linearity,
pressure drop and aerodynamic
coefficients can be simulated
to support from the style
mode development up to
detail duct design.
|
 |
|
|

Using
FEM(Finite Element Method)
and BEM(Boundary Element
Method) based NVH simulation
technologies, all kinds
of NVH performances such
as the noise level, idle
shake, wheel shake, road
shake and harshness is
assessed to define the
direction of design for
performance improvement.
And improved design will
be suggested by sensitivity
analysis, optimization
technique and even experience
based ad-hoc iterations.

As
the start of chassis engineering
activity, Kinematics and
compliance data are generated
using commercial and in-house
softwares to set-up the
initial hard points set.
And full vehicle handling
performance simulation,
durability load data generation
and tip-in / tip-out movement
analysis of the engine
mounting to improve the
dynamic behaviors of the
vehicle are performed
down the road of chassis
system development. |
 |
|
|
| |
 |

We
can predict structural
weakness of the part,
system and body structure
by performing fatigue,
damage, stress and modal
analysis. And then we
change the design to alleviate
the excessive stress level
before making parts.
