| 摘 要： | 理论上研究了盘形聚能器的轴对称纯径向振动和纯扭转振动。所用盘形聚能器的厚度,沿半径按阶梯形,锥形和指数形变化。我们获得了解析解,然后给出了共振频率、速度分布、振幅比和节点位置公式。最后用两例实验来验证我们的理论,实验结果与理论符合地较好。

| Abstract: | Axis symmetrical pure radial and pure shear vibrations were investigated theoretically for disk concentrators, whose thickness varying step-wise, linearly or exponentially with radial distance. Analytical solutions were obtained, and the formulae for resonance frequency, velocity distribution, amplitude ratio and node location derived. Two experimental examples showed good agreement with theory. |
