在传统六边形蜂窝结构的基础上添加加强筋,提出了增强蜂窝结构,通过有限元模拟的方法对其在准静态压缩过程中的面外力学行为进行研究,并与传统六边形蜂窝结构进行了对比。研究发现,加强筋的加入显著提高了其面外抗压强度与吸能性,其中对边强化蜂窝结构的平均压缩力最多可提高166.8%,比吸能最多可提高38.53%。增强蜂窝结构在压缩过程中的变形模式均为渐进折叠式,与传统六边形蜂窝结构相比其叠缩褶皱数量增多,变形过程更为稳定,并且具有更多的塑性应变集中区。此外,通过开展参数化研究发现,比吸能与单胞壁厚呈正相关,与单胞边长呈负相关关系。通过对增强蜂窝结构力学性能进行综合分析,发现对边强化峰窝结构是最优的强化方式。

陶俑是对生人社会所对应人物的真实反映,为研究古代社会提供了重要的实物资料。骑马乐俑作为乐俑的一类,最早出现于十六国时期,是对两汉军乐俑的继承和发展,这一时期因骑兵大量出现,骑乐成为军乐队的重要组成部分。北魏时期由于孝文帝推行汉化政策,骑马乐俑几近消失,基本被立俑形象的军乐俑替代。东魏北齐在统治者强烈要求恢复鲜卑旧俗的情况下,骑马乐俑随葬性质与十六国接近,属军乐俑性质。西魏北周时期,在鲜卑文化与汉文化融合发展的时代背景下,骑马乐俑虽仍有军乐队作用,但更多为仪仗乐队功能。
