摘要：

Using the finite element software ANSYS, a physical model was developed for dynamic analysis of a sandwich plate reinforced with resinic columns. The SOLID45 elements were used to calculate its buckling, free vibration and transient response. The effects of their material properties and distributions of the resinic columns on the plate's buckling loads and natural frequencies were studied. The displacement response of the plate under a transient shock was also discussed. The results showed that the resinic columns have some contributions to the mechanical properties of the sandwich plate; the influence of the resinic column modulus on the buckling and vibration of the composite plate is small; however, the distribution effect of the resinic columns on the mechanical properties of the composite plate is considerable.
