论文摘要
在存在浮动弹性板的情况下,在垂直垂直振荡的容器中,矩形垂直振荡的容器中的站立表面波在实验和理论上研究了。图案的不稳定性和波长的阈值幅度是频率的函数。基于哈密顿方法的理论模型用于描述系统。使用实验性衰减系数,我们看到该理论与实验之间的阈值幅度相当一致。同样,从该理论获得的分散关系与实验一致。
The standing surface waves in a rectangular vertically oscillating vessel filled with water (Faraday waves) in the presence of a floating elastic sheet are studied experimentally and theoretically. The threshold amplitude of the instability and the wavelength of the patterns are measured as a function of the frequency. A theoretical model based on Hamiltonian method is used to describe the system. Using the experimental attenuation coefficients, we see a very good agreement between the theory and the experiment for threshold amplitude. Also, the dispersion relation obtained from the theory is consistent with experiments.
