MSC 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 process.

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 sash.

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.”
