英文摘要	According to the theory of incompressible porous elastic medium and the continuum theory of random vibration, the random vibration equations of transverse bending on fluid-saturated porous elastic plate were established with the uniform load under the condition of diffusion of pore fluids along the plane direction. Through the analysis on the response of the displacement of plate with simply supported edges, the power spectral density function and variance and other digital features of the displacement plate with simply supported edges can be obtained when the input of uniform load is stationary random process. As a numerical example, considering saturated porous plate with simply supported edges under the uniform load in an ideal white noise stationary random, the power spectral density function of the displacement response is analyzed under different parameters and the damping effect of the flow-solid coupling term on the board displacement is also discussed. The results show that random vibration in the plate can be controlled by changing the coefficient of permeability in the pore fluid.
