橡胶基复合靶抗贯穿特性的近似分析方法

采用体积含量加权的方法确定了复合靶等效状态方程参数,采用纤维含量平方外推的方法确定了复合靶的等效强度。然后利用球腔膨胀和柱腔贯穿相结合的方法提出了一种分析计算钢球贯穿橡胶基复合靶的近似分析模型。计算方法简明、高效,而且对剩余速度和临界穿透速度等的计算结果与已有实验有良好的符合。

AN APPROXIMATE ANALYSIS FOR ANTI-PENETRATION PROPERTIES OF RUBBER-MATRICES COMPOSITE TARGETS

In this paper the equivalent parameters of state equation and the equivalent strength for the composite targets are determined by the volume content weighted method and the fiber content quadratic exterpalation method, respectively. Then an approximate analysis model for computing the penetration of a steel ball into rubber-matrices composites targets is presented by combining the circular cavity dilatation method and the cylindrical cavity penetration method. The computational method is very concise and highly efficient,and the computational results for the residual velocity and the critical penetrating velocity show reasonable agreements with the experiments.
