| Abstract: | The Hoff sandwich plate theory was applied to predict the natural frequencies and modal loss factors of constrained structure. The calculating result indicated that the error of the method of predicting the natural frequencies and modal loss factors of constrained structure was very small, and was closed to ANSYS calculating result or other author's calculating result. The method based on Hoff sandwich plate theory is suitable for calculating the natural frequencies and modal loss factors of constrained structure. |
