クラシックギターの数値モデルの構築

（主要構造部の材料特性の実験的同定）

抄録

Classical guitar has an aging effect that can be expected to improve sound quality by playing. However, the mechanism of its effect has not been clarified. Therefore, we are conducting research to clarify the structure of classical guitars and the characteristics of their components, build numerical models based on them, and elucidate the mechanism of the aging effect by numerical analysis. Here, the material properties of the component wood of a guitar with orthogonal anisotropy properties were optimized by taking into account the effect of the restraint conditions during the test. The spring elements and damping characteristics were obtained to clarify the influence of support conditions.
