英文摘要： Battlefield survivability of military wheeled tactical vehicles (referred to as military vehicles) as victims of landmines or the improvised explosive devices (IED) attacks is directly related to the vehicle occupants and military equipment safety, and it will also affect established tactical missions. Enhancing the anti-mine protection capacity of our military vehicles through independent research and development as soon as possible is of great significance to reduce casualties and to protect the operational capability of our army and so as to national defense and security. The core aim of this project is to improve the vehicles' occupant damage protection capability subjected to landmine blast wave and fragments penetration coupling loads. Experimental tests, theoretical analyses combined with numerical simulations, together with the integration of functionally graded material (FGM) design and advanced composite structural design, are used in the design optimization of the innovative anti-mine armor for military vehicles. This armor with metal lattice material core has excellent impact energy absorption characteristics and anti-fragment penetrating capability. This work and its application can provide new ideas and theoretical basis for the lightweight design of vehicle anti-mine armor, and are expected to effectively enhance the anti-mine capability of China-made military vehicles, while promoting the application of new functional materials such as the composite metal lattice in the field of explosion safety and protection.
