3322 被衝撃体から発生する放射音測定による衝撃力の同定 : FEM解析による伝達関数の決定(G03-1 衝撃・動的挙動,G03 材料力学)

抄録

It has been studied about the identification of the impact force by measuring the sound pressure. In these studies, the transfer functions between the impacted force and the sound pressure were obtained by the experimental method. In this study, the relationship between the impact force and the sound pressure is obtained by the analytical and the numerical calculations. Thus, the transfer function can be obtained without the extra experiment. And the impact force can be given by measuring the sound pressure only.
