Small- and mid-size companies that are
dealing with sound and vibration issues or consulting services have always had
a limited selection of affordable software for basic statistical energy
analysis work. The supply has not become better during the last 10 years, and
licenses for available commercial products are currently quite expensive and
practically out of reach for other than really large companies which
extensively use the method.
A new version of software for basic,
“classic” SEA is presented. It is developed as an enthusiast project by the
author. It is aimed to satisfy users without the direct need for 3-D modeling
features and other features that are not really part of the basic
method. It uses a simple but illustrative network model diagram as the
graphical interface, originally introduced as a concept in the first versions
of the well known Auto-SEA™ software. This limits the programming work to the
essentials of the SEA calculations and presentation of results. It is
programmed in Microsoft Visual Basic 2005™ and relies extensively on Microsoft
SQL databases for model and general data storage and access. The software is
believed to be well adapted to educational needs as well as the needs of
analysts with a relatively good knowledge of the fundamentals of SEA and its
application limits. It runs on all Windows platforms, including 64-bit
versions.
A couple of practical examples are
presented. The use of a relatively small SEA model during the very early
concept study of a new product is shown as well as a comprehensive modeling of
a large built-up structure such as a ship or an off-shore platform.
