| 摘 要： | 应用有限元软件ANSYS,分析树脂柱对点阵增强型复合材料夹层板力学性能的影响.对夹层板建立物理模型,采用8节点SOLID45实体单元,计算夹层板的屈曲、自由振动以及受冲击荷载时的瞬态动力响应.研究了树脂柱的材性及分布对夹层板屈曲载荷及自振频率的影响,讨论了瞬态冲击荷载作用下树脂柱对降低竖向动力位移的正面作用.结果显示,树脂柱的存在对夹层板的力学性能有一定影响,其中树脂柱的材性对夹层板屈曲及动力学特性的影响有限,而树脂柱的疏密程度对点阵增强型复合材料夹层板的力学性能有着明显的改进作用.

| Abstract: | 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 column... |
