Research on the vibration characteristic of a percussion instrument cymbal by modal analysis : Verification of experiment modal analysis and theoretical modal analysis, comparison, and structure optimization

非線形最適化法は周波数領域で多点応答に拡張したものである。この手法をMATLAB言語を使用して組み込んだシステムを打楽器のシンバルに適用し、それと同時に有限要素法の結果と比較した。また、今回はさらに発展して構造変更の最適化を行った。Using nonlinear optimum method, maximum likelihood modal parameters in statistics are identified in the frequency domain with multiple frequency response functions. User interfaces are constructed with MATLAB in personal computer. This system is applied for percussion cymbals and compared with FEM results. Moreover, it developed further and structure change was optimized this time
