摘　　要：基于混合物冷能叠加原理,由各组分Hugoniot数据计算了密实材料的冲击压缩特性。再从等压路径出发,结合Wu-Jing模型由热力学关系得到了具有一定孔隙率多功能含能结构材料的冲击压缩特性计算方法。以W/Cu、Al/Ni、Ni/Ti和Al/Fe2O3/epoxy等典型颗粒金属材料及含能金属材料为例,计算了其冲击压缩过程中相关Hugoniot参数。计算结果与已有实验结果吻合较好,多功能含能结构材料冲击压缩特性受材料孔隙率、材料配比等影响明显。Based on the cold energy mixture theory, the equations of state were given for the compac- tion multifunctional energetic structural materials （MESMs） under shock compression by using the Hugoniot relations of the components. And combining the above method and the Wu-Jing model, the equations of state were proposed for the porous MESMs under shock compression along the isobaric paths. To verify the accuracy of the calculations, the Hugoniot relations were calculated for the typi- cal metal particle mixture （W/Cu） and the typical MESMs （A1/Ni, Ni/Ti and A1/Fe203/epoxy）, re- spectively. The theoretical calculations agree well with the corresponding experimental results. The shock compression characteristics of the MESMs can be evidently influenced by their porosities and the proportions of the components in them.
