Description

<p>Aiming to improve the value of cars, Mazda has been developing technologies with the concept of Material Model-Based Research (MBR) for the efficient development of innovative materials. In this study, aiming to achieve desired acoustic characteristics with a limited mass and volume of a porous sound-absorbing material that improves quietness in a car, we have developed technology that efficiently designs the microstructure of the material. This technology is a combination of the homogenization method that derives an average macro-structural property from the micro-structural property of the material and Biot model which is relatively simple prediction model for sound absorption/insulation performance. This technology enables highly accurate and efficient parametric calculations for microstructure's shape and size. Here we introduce the outline of this technology and the application of the technology to engine encapsulation.</p>
