Industry standard formats
Finite element models are imported from NASTRAN bulk data
deck files ensuring compatibility with FE meshing tools. Mechanism
drive functions can be linked with external data files in MTS
RPC III/Pro, nCode DAC or ASCII format. Simulations driven with
such external data can be switched from one event to another
simply by changing a file reference. Simulation results can
be exported in MTS RPC III/Pro, nCode DAC or ASCII format files.
Animations can be exported in MPEG-1, MPEG-2 or AVI formats,
and stills in JPG, PNG, BMP or RGB/IV(3D only) formats.
Large models and long time histories
Large FE meshes are easily handled due to the innovative
use of superelement technology utilizing a combined static and
dynamic reduction. Further, efficient modeling and post-processing
is ensured through high performance 3D graphics. The equations
of motion are only solved for the reduced system and the number
of equations are independent of FE mesh sizes. This enables
simulation of long time histories, even for models containing
large FE meshes.
Tire and road models
Tire and road models are provided to enable fully analytical
vehicle simulation. Currently, the MF-Tyre and SWIFT tyre models
developed by Delft-Tyre (TNO Automotive), and FTIRE developed
by COSIN, are supported. MF-Tyre and SWIFT are implemented through
the Standard Tire Interface (STI), while FTIRE implementation
is based on the COSIN Tire Interface (CTI). The complete Delft-Tyre
libraries are provided as add-ons.
Durability assessment with nCode
Durability assessment is provided through a seamless interface
to FE-Fatigue from nCode International. For selected elements
a peak-valley extraction is performed simultaneously with the
stress or strain recovery from the non-linear structural dynamics
solution. This is used to calculate a rainflow matrix as input
to the fatigue solver. Durability analysis results can be viewed
as contour plots on the model in the 3D graphics environment.
In addition, virtual strain gage measurements can be obtained
from the model.
Multi-event duty cycle analysis
Result sets from different simulations can be combined in
a multi-event duty cycle analysis. An intuitive user interface
provides a clear overview on available result sets and duty
cycle management.
