Technical Field
[0001] This invention belongs to the field of explosion-proof testing equipment, and in particular to a rapid field explosion testing device for studying the explosion-proof performance of planar plate components. Background Technology
[0002] Since the 20th century, with the deepening application of various cutting-edge technologies in the military field, the environment faced by blast-resistant armor has become increasingly complex. The greatest threat comes from various explosive impacts, and blast resistance and impact resistance are crucial components of the blast-resistant armor's viability. Therefore, evaluating the blast resistance performance of plate structures (such as strain and fragmentation under explosion conditions) is a major concern for designers. Composite materials, such as metal plates coated with blast-resistant coatings, are widely used in various engineering fields, such as aerospace and blast protection, due to their high specific strength, specific stiffness, and design flexibility. These materials are often used in critical and special locations, making the blast resistance characteristics of such structures particularly noteworthy.
[0003] Patent CN102102965A discloses a method for physical simulation of armor-piercing damage testing using electrode-induced arc micro-detonation. This method utilizes an electrode-induced arc micro-detonation device to generate high-energy detonation waves that penetrate a target plate. Based on the difference in crater depth between two different target plates under the same detonation parameters, the difference in ballistic resistance between the target plates is determined. The ratio of the penetration depths is used as the equivalent relationship of the ballistic resistance effectiveness of the two target plates, thus establishing an equivalent target plate. Its drawback is that it is only suitable for indoor testing. In actual explosion-proof processes, irregularly shaped plate components have a relatively large area, typically tens of square meters. This method cannot reproduce the actual explosion environment, and the parameters obtained are only estimates.
[0004] Chinese patent application CN 111458372 A discloses an explosion test chamber for studying the blast resistance of plate components. The chamber includes a hollow, top-opening explosion chamber body. A simulated plate component is detachably placed horizontally at the top opening of the explosion chamber body. Detachable component fixing mechanisms, adapted to the simulated plate component, are provided at the left and right ends of the top of the explosion chamber body. Detachable side panels, adapted to the simulated plate component, are provided on the front and rear sides of the top of the explosion chamber body, with the top of the side panels flush with the top of the simulated plate component. The explosion test chamber provided by this invention forms a single, controllable boundary condition at both ends of the simulated plate component. In explosion simulation tests of plate components, it can reflect the true response of the plate component under explosive loads, which is of great significance for the study of the blast resistance of plate components. Furthermore, the components of the explosion test chamber are detachable, making the chamber easy to disassemble, transport, and reusable. Its disadvantage is that the structure is relatively complex and cannot realistically simulate the specific environment of an explosion.
[0005] Patent CN 207832109 U discloses a displacement measuring device for an explosion-proof test plate-shaped specimen. The device includes a cubic support body with a specimen plate fixing assembly on top. The upper fixing rod of the specimen plate comprises an arched square tube and a hollow round tube welded inside the arched square tube. The lower fixing rod is a hollow round tube welded to the upper edge of the support body. The specimen plate is installed between the upper fixing rod and the lower fixing rod. Both ends of the upper and lower fixing rods have mounting holes, with the lower fixing rod and the upper fixing rod corresponding to each other, and their mounting holes also corresponding. The lower fixing rod and the upper fixing rod are connected by bolts through the mounting holes, and the outer ends of the bolts are secured with nuts. This invention has a simple structure, reasonable design, accurate measurement, and high data precision. However, its disadvantages include a relatively complex structure, inconvenient disassembly, high cost, limited versatility, and suitability for indoor operation; it cannot realistically simulate the specific environment of an explosion.
[0006] Patent CN 111089808 A discloses an invention related to a test device for the blast resistance characteristics of composite material laminate structures, belonging to the field of material protection characteristics technology. It includes a cement base, a steel clamp, an explosive support, and a sensor measuring device. The cement base is a prism, with a certain area at the center of its inclined surface serving as the sample contact area. A cavity is opened behind the contact area, and bolt holes are present around the perimeter of the contact area and around the steel frame clamp. Each of the four sides of the sample contact area on the cement base has a pre-fabricated groove, and the test sample is fixed to the inclined surface of the cement base with bolts. The steel clamp is a rectangular frame with built-in raised grooves, and five bolt holes are present at corresponding positions on each of the four sides. The explosive device is angled and adjustable, with the explosive installed at one end in the air. The sensor measuring device is fixed at the same height as the test sample. This invention has a simple structure, is easy to install, can ensure the fixed boundary conditions of the composite material laminate, and can simulate the blast resistance performance of the composite material laminate structure under near-field explosive loads. It often uses partial samples for indoor testing, but its disadvantage is that it cannot measure actual explosive values under real-world conditions.
[0007] In actual explosion-proof testing, irregularly shaped plate components are generally large in size and difficult to measure. To effectively measure the parameters of these components, a realistic simulation of the explosion environment is necessary to obtain accurate test parameters. This requires high-energy field explosion simulation tests. Even for the same irregularly shaped plate component, different actual explosion environments need to be simulated during explosion testing, necessitating multiple tests. Furthermore, in near-field or contact explosions, excessively strong boundary conditions can cause the test component to fail first at the boundary, resulting in significant damage. Conversely, insufficient boundary conditions can lead to overall displacement of the test component, leading to inaccurate parameter measurements. Therefore, suitable boundary conditions need to be determined based on actual field testing conditions. Field explosion simulation tests require burying the explosive material on or below the ground surface and installing testing devices weighing several tons or even tens of tons on the ground, making the installation of these devices highly dangerous. Given the large size of irregularly shaped plate components, traditional fixing and testing devices cannot meet the actual testing requirements. Research and inventions on fixing devices for composite material explosion-proof testing are limited, and existing fixing and testing devices are often overly complex in structure, difficult to operate at field explosion sites, costly, and inflexible.
[0008] In summary, the existing technology lacks a rapid field explosion testing device that can accurately measure the explosion resistance of irregularly shaped plate components. Summary of the Invention
[0009] The technical solution adopted in this invention is as follows.
[0010] An easy-to-install field testing device for the blast resistance performance of irregularly shaped plate components, including a support frame, the irregularly shaped plate component to be tested, a clamping assembly, an explosive or explosive substitute, and a remote detonation device.
[0011] The support frame includes a support frame with a "U"-shaped top surface, a support for the irregularly shaped plate component to be tested, and several support legs, with the top of each support leg connected to the support frame. The support for the irregularly shaped plate component to be tested is located below the support frame and connected to at least one support leg. The support legs are placed on the ground of the explosion test site. The irregularly shaped plate component to be tested is placed on the support for the irregularly shaped plate component to be tested, with the top of the irregularly shaped plate component to be tested located inside the support frame and flush with the top surface of the support frame. At least one pair of opposite sides of the support frame is provided with a lifting ring on its outer side.
[0012] The clamping assembly includes a rectangular cross-section clamping frame, a clamping plate, and several counterweights. The clamping frame is placed on the irregular plate component to be tested, and the four sides of the clamping frame are aligned with the four sides of the support frame. Each counterweight is placed on the clamping plate.
[0013] The explosive or explosive substitute is buried below the ground directly beneath the support frame at the explosion test site, or the explosive substitute is placed on the ground below the support frame.
[0014] The remote-controlled detonation device is located at a safe distance from the explosive or its substitute. A space is formed by a pressure frame, a pressure plate, and the irregularly shaped plate to be tested; an on-site explosion measurement device is connected to the bottom surface of the pressure plate; the on-site explosion measurement device is connected via wiring to a measurement and control device located at a safe distance from the explosive or its substitute.
[0015] The beneficial effects of this invention are: 1. Rapidly establishes test conditions in the field. In use, first, place the explosive or explosive substitute at the site. Then, at a safe distance outside the site, install the field explosion test device as needed. Use a crane with explosion-proof capabilities to lift the support frame to the ground directly above the explosive or explosive substitute, and gently place it. This quickly establishes test conditions in the field. Its advantages are twofold: firstly, it solves the inconvenience of field installation, and secondly, it is relatively safe. The pressure frame, pressure plate, and the panel to be tested form a sealed space. The bottom surface of the pressure plate is connected to the field explosion measurement device. The field explosion measurement device is set up in a sealed environment to avoid wave diffraction, resulting in more reliable measurement data.
[0016] 2. The remote-controlled detonation device is safer to detonate outside the explosion test site.
[0017] 3. An off-site explosion observation device is provided, enabling remote measurement and observation. After the explosion test is completed, the explosion resistance performance of the tested planar plate component can be calculated by measuring the components.
[0018] 4. The functions of the pressure plate are: firstly, to provide a place for an appropriate number of counterweights, preventing the massive shockwave from an explosion from causing the entire irregularly shaped plate component under test to move; and secondly, to prevent excessive weight from causing premature failure of the test component at the boundary during a near-field or contact explosion, resulting in greater damage at the boundary. Secondly, to balance the counterweights, ensuring their uniform action on the pressure frame, forming a simple peripheral fixing system for the plate component. Thirdly, the pressure plate, counterweights, pressure frame, and the flat plate component under test form a sealed space, within which an on-site explosion measurement device can be installed. This solves the problems of large flat plate components and the often overly complex, costly, and inflexible structures of traditional fixing and testing devices, which are difficult to operate.
[0019] 5. The explosion testing device provided by this invention, based on the preliminary test results of the planar plate component to be tested and similar components on-site, determines the required boundary conditions for the planar plate component to be tested, determines a reasonable number of counterweights, and the measured data is very accurate. Moreover, each component is detachable and can be quickly assembled in a safe off-site environment, making it easy to operate and highly versatile.
[0020] 7. The device is easy to disassemble, transport, and recycle. The invention also has the advantages of simple structure, convenient use, and comprehensive and accurate measurement data, and has great practical value.
[0021] As a preferred technical solution, the support frame for the irregularly shaped plate component to be tested includes two connecting rods, four vertical plates, and two horizontal rods; each of the four corners of the support frame is connected to a supporting leg; the two supporting legs on both sides of the irregularly shaped plate component to be tested are connected by a connecting rod, and each connecting rod is connected to the support frame through two vertical plates perpendicular to the ground. Each vertical plate is provided with several horizontal rod height adjustment holes at different heights from the ground; the support frame for the irregularly shaped plate component to be tested includes at least two horizontal rods parallel to the ground, and the two ends of each horizontal rod are inserted into the horizontal rod height adjustment holes of a vertical plate. Using this technical solution, the height of the horizontal rods can be adjusted to accommodate irregularly shaped plate components of different heights to be tested.

[0024] As a preferred technical solution, the off-site explosion observation device includes an off-site camera.
[0025] As a preferred technical solution, baffles are provided on each of the four sides of the bottom surface of the pressure plate to prevent horizontal displacement of the pressure plate on the pressure frame. Small through holes for wiring are provided horizontally on the pressure plate.
[0026] As a preferred technical solution, the on-site explosion measurement device includes one or more of the following: a close-range explosion-proof camera, a close-range air pressure sensor, a close-range displacement measurement device, a close-range strain measurement device, and a close-range pressure measurement device. The inner circumferential surface of the pressure frame is provided with several scale lines to facilitate observation of the movement of the planar plate component under test.
[0027] As a preferred technical solution, an on-site explosion measurement device mounting box is connected to the bottom surface of the pressure plate, and the on-site explosion measurement device is installed inside the on-site explosion measurement device mounting box.
[0028] As a preferred technical solution, the longitudinal section of the irregularly shaped plate component to be tested is arc-shaped, or the cross section of the irregularly shaped plate component to be tested is annular.
[0029] As a preferred technical solution, a foam metal board is horizontally fixed within the support frame. The explosion-proof performance of the flat panel component under test is calculated based on the degree of penetration of the foam metal board into the ruptured irregular-shaped panel component.
[0030] As a preferred technical solution, the bottom end of each support leg is screwed with a pad for adjusting the height of the irregularly shaped plate component to be tested. The pad is used to quickly adjust the distance between the flat plate component to be tested and the explosive from a safe distance in the field, which is relatively safe. Attached Figure Description
