Types of Data
Input
The information
used by the
software to
perform a
Natural Input
Modal Analysis
includes the
geometry of the
structure, the
measured
vibration
responses and
the sampling
interval. The
geometry
information
includes a
description of
the measurement
points, the
measurement
directions and a
wire-frame /
surface
representation
of the structure
that is used for
animation of the
mode shapes.
The user can
also specify how
the unmeasured
degrees of
freedom (DOF)
should move as a
function of the
movement of the
measured DOF’s.
For instance,
the motion of an
unmeasured DOF
can be
interpolated
between two
adjacent
measured DOF’s.
Multiple
Test Setups
Using multiple
test setups allows
the user to
obtain a good
spatial
resolution of
mode shapes with
a limited number
of sensors.
During testing
one can select
one or more
sensors as
references and
then move the
remaining
sensors
throughout the
structure until
vibration
responses have
been measured at
DOF’s of
interest.
OLE
Automation
The OLE
automation
standard allows
the user to
import input
data from any
software that
supports the
standard.Typical
examples are
Microsoft Word,
Microsoft Excel,
and MATLAB. The
user can also
write customized
applications in
e.g. Microsoft
Visual Basic and
import data and
geometry
directly.
Import from
data files and
SVS
Configuration
File
All geometric
data can be
specified in the
SVS
Configuration
File, which can
be easily
generated using
a text file
editor. Response
data can be read
from ASCII files
with the data
stored in a
matrix format in
which the time
series are
organized column
by column. In
addition, data
stored in TEAC
HDR format, UFF
ascii and binary
and Microsoft
Wave file format
can be uploaded
through the use
of the
configuration
file.
This enables the
user to import
data from data
acquisition
systems storing
data various
formats.
Import from
Universal File
Format (UFF)
Input data can
be imported from
data files
stored using the
Universal File
Format.
This makes it
easy to analyse
data from
measurement
systems that
support this
standard. Nodal
information
imported via UFF
data set #15,
trace lines via
UFF data sets
#82, surfaces
via UFF data set
#2412
(triangular
plate elements).
Measurements and
DOF information
via UFF data
sets #58 (ASCII
or binary).
Import from
ARTeMIS Testor
All input data
can be
transferred
directly from
ARTeMIS Testor
by a click on a
button in the
Export task of
the ARTeMIS
Testor.
Import from
MATLAB
All input data
can be
transferred
directly from
MATLAB without
intermediate
file
storage.This
feature is
useful for
analysis of
structural
response
simulations
performed with
MATLAB.
