湍流附面层作用下弹性板的随机振动

ON THE RANDOM VIBRATION OF ELASTIC PLATE

  • 摘要: 本文用富里叶变换和特征展开的方法讨论了弹性薄板在重介质(水)中的随机振动问题;在排除各振动方式通过介质相互作用的条件下,严格考虑了介质的反作用;并根据近年湍流附面层的实验结果,确定了用δ函数描写“准声”相关函数的适用范围。
    Abstract: In this paper,the random vibration of elastic plate submerged in water is discussed with the method of Fourier transform and expansion in eigenfunctions.The reaction of the medium to the vibrating plate was strictly investigated under the condition that the interaction between the different modes had been excluded.The range in which the Dirac δ function might be used to describe the correlation function of quasi-sound field in turbulent boundary layer was determined based on the experimental results in the last years.
