环氧泡沫塑料易碎保护盖结构设计及实验验证
Structure Design and Verification Test for Fragile Protection Closure Made from Epoxy-foam Plastics
摘要
Abstract
The stress distribution of the fragile protection cover made from epoxy-foam plastics was analyzed under the given blast load by the method of the finite element simulation. And the strain distribution was tested under the safe load. So the two drafts of the structure were designed based on the results of the research on the destroy forms of the wing slip area of cover structure which was carried out according to the properties of the base material. The explosion experiments besides the static pressure and gas dynamic pressure were executed to the specimens. The results showed that the weakening groove laid along the structure in vertical, horizontal and edge lines contributed to root fracture and uniform segments at the critical pressure, and that the structure design was reasonable and the analysis method was accurate, which were proved to be the basis for the application of fragile protection cover.关键词
