Our Research
Development of vibration / noise prediction technology
Felt and urethane foam are widely used as soundproofing materials for automobiles. In order to improve sound absorption and insulation performance, it is often used by laminating with rubber sheets, vinyl films, felts, etc. With commercially available analysis software for performance prediction, the measurement results and prediction results show good agreement with felt and urethane foam alone, but the analysis accuracy is poor and the acoustic characteristics are poor in the laminated state (especially when non-breathable materials are laminated). Is not fully predictable.
In this research, we are conducting technical research to make it possible to predict the sound absorption and insulation performance of laminated soundproof materials including felt and urethane foam.
Quietness of automobiles (reduction of noise)
Various noises such as engine noise, tire noise, and wind noise come into the inside of a car. We will research technologies for predicting and quieting these in-vehicle noises. Specifically, using commercially available hybrid SEA (statistical energy analysis) software, it is possible to create an analysis model, compare experimental measurement results and calculation results, and investigate the relationship between changes in acoustic characteristics and changes in vehicle interior sound due to component changes. I am studying.
Vibration acoustic analysis of stringed instruments
Stringed instruments are handmade by craftsmen or manufactured in factories, but the current situation is that they are manufactured and adjusted based on past experience and intuition of craftsmen. How the structure (shape and thickness of the plate) and materials will affect the sound (vibration), the difference in tone due to the difference in musical instruments, and what kind of tone is comfortable for humans to hear. We are conducting engineering research using experiments and CAE.
