The authors used Mindlin's equation, and calculated the circular plate natural mode with a solid shaft under the boundary condition of a fixed inner diameter. As the result, the caclulated natural frequency of the low mode of the thick circular plate differed greatly from the one measured by model analysis. The causes were analyzed on the (1,0) mode of vibration, which had the biggest error of 78 percent. It was revealed that the elastic deformation on the boundary between the circular plate and the solid shaft, and the bending deformation of the had a strong influence on the natural frequency. By taking both influences into account, the natural frequency of the (1,0) mode was corrected to within a 5 percent error.
