The metal honeycomb is a kind of material which has multi-cellular honeycomb nest structure,it is the ideal energy-absorbing materials for its advantages such as low density,low stiffness, strong shock resistance and controllable compression.Metal honeycomb plays an important role in the field of high-speed trains for it can effectively absorb tremendous impact energy when collision between trains occurs,it is the ultimate security guard to protect the passengers or other payloads from significant harm,and an important part of high-speed train passive safety technologies.In recent years,because the manufacturing of high-strength metal honeycomb is very difficult,the research and application of energy absorbing material which based on high-strength metal honeycomb has become an important high-tech industries.
