Test system for simulating anti-explosion characteristic of target under confining pressure condition

Abstract

The invention relates to a test system for simulating anti-explosion characteristics of a target under a confining pressure condition, which comprises the target and an explosion source arranged at the top of the target, the test system further comprises a plurality of pressing plates symmetrically arranged on the periphery of the target, supporting bases arranged on the sides, away from the target, of the pressing plates, flexible oil bags arranged between the pressing plates and the supporting bases, and a pressing machine connected with the flexible oil bags. The two sides of the flexible oil bag make contact with the pressing plate and the supporting base respectively, and the side, away from the flexible oil bag, of the pressing plate makes contact with the target. A plurality of flexible oil bags symmetrically arranged on the periphery of a target are pressurized through a pressing machine, and the flexible oil bags expand to apply confining pressure to the target. An explosion source is arranged on the target, impact waves act on the target in a pressed state, the anti-explosion characteristic of the target under the confining pressure condition is simulated, and dynamic and static combined loading of the target can be achieved.

Description

technical field [0001] The invention relates to a test system for simulating the anti-explosion characteristics of a target under confining pressure conditions, and belongs to the technical field of explosion damage research under confining pressure conditions. Background technique [0002] With the rapid development of earth-penetrating weapons, their strike effectiveness has become higher and higher, and the threat to protection projects and important military facilities has become more and more serious. As the penetration depth of earth-penetrating weapons increases, their damage to deep-ground protection projects becomes more and more severe. Under the action of the overlying strata, in-depth protection projects such as tunnels and chambers are always in a state of high confining pressure, and the confining pressure will have an important impact on the dynamic mechanical behavior of the protective structure. [0003] At present, there are not many studies on target conf...

Problems solved by technology

This method uses the stress wave generated by the impact of the bar to load the specimen, but is limited by the small size of the bar, so it can only realize the impact loading of the small-sized specimen under the confining pressure state, and it cannot be realized without explosive loading.
