Abstract

The invention provides an active protection system with the state reversible. The active protection system contains electrorheological fluid. Due to the fact that the electrorheological fluid has flowability and the characteristic that the liquid state and the solid state can be switched under excitation of high-voltage electric energy, when being subjected to current excitation, the electrorheological fluid can be rapidly changed into the solid state; in addition, the solid electrorheological fluid is quite high in strength; and therefore, the active protection system can effectively resist to impact of projectile bodies. According to the active protection system, material characteristics are utilized, and effective repeated defense against projectile body impact is achieved through electric energy. The active protection system is combined with a radar monitoring system, the projectile bodies can be monitored; and active and advance defense can be conducted conveniently. The active protection system is applicable to occasions where explosion is likely to be caused such as a chemical plant, a fire scene and a battlefield.

Description

technical field [0001] The invention relates to the field of anti-shock technology, in particular to an active protection system with reversible state. Background technique [0002] In places prone to collision or explosion, such as chemical plants and battlefields, the collision or explosion will cause serious casualties to vehicles and personnel, and it is necessary to protect armored vehicles or personnel. Therefore, protective devices are essential. [0003] The current protective devices mainly include metal materials, ceramic materials, and high-performance fiber composite materials. For metal materials, after being hit by flying pieces produced by impact or explosion, they will deform and reduce their subsequent protection ability. For ceramic materials, it is easy to break and has weak continuous protection ability. For high-performance fiber composite materials, their protective ability benefits from their high tensile strength, but this material is easily punctu...
