Japan’s LIXIL Selects Actran to Develop Next Generation High-Performance Sound Insulation Window Sash

Software Corporation, a global leader in helping product
manufacturers to advance their engineering methods with simulation
software and services, today announced that LIXIL, manufacturer of
building materials and housing equipment, has selected MSC Software's Actran
acoustic analysis software to predict sound insulation performance and
improve the quality of next generation window sashes.
Recently, diversification of open-close design and the type of glass
used in the design and development of window sashes has made the
evaluation and experimental testing of sound insulation performance in
products difficult. As a result, the cost of product testing has
increased. For this reason, LIXIL is now relying on numerical
simulations for further validation and testing leading to a reduction in
the number of physical tests, lower costs, and a shorter development
Actran was selected because of the highly reliable support and expertise
provided by the FFT team which delivers deep acoustic application
knowledge and technological skills. LIXIL is also working on
high-precision prediction and control of sound insulation performance
through the calculation of sound transmission loss (TL) of the window
The diffuse sound field feature in Actran,
which reproduces the experimental reverberation room/box, made it
possible to improve the accuracy of TL analysis. Also, in addition to
the glass, there are various modeling features to analyze vibration and
acoustic characteristics involving the complex structure of the window
sash. For accuracy evaluation of the Actran results, TL is compared with
Actran results and experimental results, with some specification
changes, such as different open-close designs for window sashes. Good
correlations have been confirmed in these comparisons. Consequently, it
is possible to replace the process of TL evaluation in physical
experiments with virtual simulation for some of LIXIL’s products,
thereby reducing experimental costs and enabling faster time to market.
“The prediction and control of sound insulation performance is expected
to become an indispensable technology in the development process of the
window sash,” said Keiichi Kato, LIXIL Corporation, Digital Technology
Promoting Office, Analysis Technology Promoting Group, Group Leader.
“Among them, the calculation of TL using Actran is providing high
efficiencies in the product development process. With the new
enhancement in Actran, I hope that in the future we will be able to
apply the technology not only to window sashes, but to large scale
problems such as actual-size architectural spaces.”
“The majority of Actran
customers have been in automotive and aviation,” said Masatake Saitoh,
Director of the FFT Division at MSC Software. “In recent years, sound
problems have gained the attention of various fields outside of
transportation because of the need to create pleasant sounds, better
customer experiences, and compliance with regulatory requirements around
noise reduction. TL analysis, such as those being used by LIXIL, is
expected to become a new possibility for the application of Actran, as
well as creating comfortable living environments, noise control of OA
equipment, and so on.”
