A Multi-Condition Matching Adaptive Adversarial Safety Structure

Abstract

Disclosed is a multi-working-condition matching self-adaptive opposite-trend safety structure. The safety structure comprises connectors, locking parts, a plurality of connected domain units and an inner filling material. Each connected domain unit is made of polymeric materials. The inside of each connected domain unit is a multiple connected hollow domain composed of a plurality of hole channels with different directions, different sizes and different shapes, wherein the multiple connected hollow domain is filled with opposite-trend nanogel materials. The multiple connected domain units can be connected mutually through the connectors and the locking parts to form different-structure different-size opposite-trend safety structures adapting to different working conditions. According to the multi-working-condition matching self-adaptive opposite-trend safety structure, impact energy is converted into friction internal energy between the insides of fillers, friction internal energy between the fillers and the multiple connected domain units made of the made of polymeric materials, and deformation energy of the multiple connected domain units, energy absorption is fast, and the safety protective effect is significant. The multi-working-condition matching self-adaptive opposite-trend safety structure can be reused, has a good energy absorption effect under the circumstance of repeated impacts, can deal with impacts of multidirectional complex working conditions simultaneously, can be assembled freely according to the space requirements of application occasions, and is high in adaptability.

Description

technical field [0001] The invention relates to an anti-trend safety structure, in particular to a multi-working condition matching self-adaptive anti-trend safety structure. Background technique [0002] At present, in the fields of bridge construction, rail transit, mining, shipbuilding and automobile manufacturing, engineers and technicians widely use hydraulic buffers and thin-walled components to absorb the energy brought by impact, so as to achieve the purpose of protecting the target structure. The principle of hydraulic buffer energy absorption is that the impact acts on the hydraulic device, and the viscous damping effect of the oil is used to absorb and convert part of the impact energy into the heat energy of the oil through the orifice and dissipate it. The hydraulic buffer device has a complex structure, inconvenient maintenance, high sealing requirements, and is sensitive to changes in ambient temperature, resulting in high production and maintenance costs.

Problems solved by technology

These materials can achieve better energy absorption effects when subjected to linear and low-speed impacts. However, once subjected to nonlinear and high-speed impacts, their energy-absorbing effects will be greatly reduced, mainly due to stress regionalization and slow material response.
