| 摘 要： | 本文是实验研究水中充气、不同离心率的铝和紫铜椭圆柱壳上的圆周波.实验观察到对称型圆周波和反对称型圆周波,发现它们的传播速度与弹性壳的曲率无关,并在理论上同水中弹性板内的对称型拉姆波和反对称型拉姆波的传播速度相一致.

| Abstract: | In this paper experimental study of circumferential waves in thin-walled air-filled aluminum and red copper elliptical cylinders with the different eccetricity in water is reported. The symmetrical mode and the antisymmetrical mode circumferential waves were found. The measured traveling velocities agree with the theoretical velocities for the symmetrical mode and the antisymmetrical mode of Lamb's waves in the elastic plate, and independent of eccentricity. |
