Improvement of performance of Kushidango-shape MHS structure

研究了一种新型高吸能超轻多孔金属“Kushidango-shape MHS结构”的控制方法。kushidango形状的MHS是一串空心球体形状的管状组件。提出了用锡焊料在低温下进行强钎焊的固结方法。对构件排列，即表观密度和内部变形行为发生改变的结构进行固结，并通过压缩和弯曲试验估计其力学性能。根据这些结果，可以对性能进行控制。为了虚拟地评估其性能，还建立了压缩和弯曲的有限元仿真模型。

Control method of a new high energy absorbing ultra light porous metal called ‘Kushidango-shape MHS structure’was examined. Kushidango-shape MHS is a tubular component in the shape of a string of hollow spheres. Consolidation method thatthe components are strongly brazed by tin solder at low temperature without heat affect was proposed. The structures in which arrangements of the components ,that is, apparent density and internal deformation behavior were changed were consolidated and theirmechanical properties were estimated by compression and bending tests. By these results, the performance can be controlled. To estimate the performance virtually, FEM simulation models of compression and bending were also established.
