The common method is to design a uniform specification of vertical wall and trench according to the general performance of most armored vehicles, use concrete and other building materials for pouring construction, and form a fixed standard specification test facility. When different types of armored vehicles need to be tested, they are all carried out on this fixed specification vertical wall and trench. In addition, if the passing ability of vehicles on vertical walls of different heights and trenches of different widths needs to be tested, a set of fixed vertical wall and trench facilities needs to be built for each specific size test requirement, and each facility is independent of each other.

[0053] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

The terms “first”, “second” and similar terms used in the present application do not represent any order, number or importance. The terms “connected” or “linked” and similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms “up”, “down”, “left”, “right” and the like are only used to represent relative positional relationships, which can change accordingly when the absolute positions of the described objects change. The embodiments of the present application disclose an armored vehicle modular test field and a test method.

[0055] The core of the present application is to provide an armored vehicle modular test field.

[0056] Another core of the present application is to provide an armored vehicle test method, which adopts the armored vehicle modular test field.

[0057] Please refer to Figure 1 .

[0058] The armored vehicle modular test field provided by the application comprises a fixed test field base body 1, a modular test device 2, and a positioning connection assembly 3. The modular test device 2 comprises a plurality of modular units 21 which can be stacked or arranged side by side. The fixed test field base body 1 is arrayed with sleeves 11 with equal spacing along the length direction, and the modular unit 21 is provided with a plug-in hole 22 coaxially distributed with the sleeve 11. The positioning connection assembly 3 comprises a conical locking piece 31 which can be plugged into the sleeve 11 and the plug-in hole 22.

[0059] Specifically, the armored vehicle modular test field is composed of a fixed test field base body 1, a modular test device 2, and a positioning connection assembly 3. The fixed test field base body 1 is formed by pouring concrete, and has a fixed height at one end. A plurality of arrayed sleeves 11 are embedded on the fixed test field base body 1 as mounting and positioning pin holes of the modular test device 2. The sleeves 11 are used to cooperate with the conical locking piece 31 to fix the modular unit 21.

[0060] A plurality of first modular units 21 are stacked on the surface of the fixed test field base body 1. Different numbers of modular units 21 are stacked according to different armored vehicles. The installation position of the modular unit 21 is set along the position of the embedded sleeve 11. A plug-in hole 22 coaxial with the sleeve 11 is arranged on the outer circumferential side of each modular unit 21. The conical locking piece 31 is sequentially plugged into the plug-in hole 22 and the sleeve 11 to fix the modular unit 21 on the fixed test field base body 1. After the conical locking piece 31 is inserted into the sleeve 11 and the plug-in hole 22, a certain interference fit is generated to realize the stable connection of the modular test device 2 and the fixed test field base body 1.

[0061] The armored vehicle modular test field described above is designed in a modular manner, so that the vertical wall height can be flexibly adjusted according to the test requirements of different armored vehicles. Each modular unit 21 of the modular test device 2 can be independently manufactured and transported, which is convenient for installation and disassembly, and improves the construction efficiency of the test field. At the same time, the modular unit 21 can be reused, which reduces the test cost. The positioning connection assembly 3 ensures the stability of the connection between the modular test device 2 and the fixed test field base body 1, and ensures the safety of the test.

[0062] The armored vehicle modular test field provided by the application will be described in more detail below in combination with the drawings and specific embodiments.

[0063] In one specific embodiment, reference is made to Figure 2 and Figure 3The module unit 21 comprises a surrounding plate 211, a framework 214 and a base plate 215. The surrounding plate 211 is internally poured with concrete 212, and the surface of the concrete 212 is paved with gravel 213. The framework 214 is arranged in the surrounding plate 211, and is used to improve the overall structural strength of the module unit 21.

[0064] Specifically, the surrounding plate 211 in the module unit 21 is welded by a metal plate and has a rectangular frame shape. The surrounding plate 211 can be made of a high-strength steel plate, which can ensure that the surrounding plate 211 can withstand the impact force when the armored vehicle climbs. The surrounding plate is internally poured with concrete 212, which can increase the overall weight and stability of the module unit 21 and simulate the thickness of the vertical wall in actual combat. The surface of the concrete 212 is paved with gravel 213, which can increase the friction between the tires of the armored vehicle and the surface of the vertical wall, so that the test is closer to the actual combat environment. The gravel 213 can also be replaced by sand particles, which can also increase the friction.

[0065] Further, the module unit 21 further comprises the base plate 215 arranged at the bottom corners of the surrounding plate 211. Adjacent base plates 215 form grooves for forklift loading operations.

[0066] Specifically, the base plate 215 is arranged at the bottom corners of the surrounding plate 211. Adjacent base plates 215 form grooves for forklift loading operations, so that when the module unit is transported, the forks of the forklift can be inserted into the grooves, facilitating the movement and installation. At the same time, the base plate 215 not only facilitates the forklift loading operation, but also enables the module unit 21 to be stacked vertically, thereby effectively saving storage space.

[0067] On the basis of any one of the above embodiments, the framework 214 comprises a space truss, and the nodes of the space truss are fixed to the surrounding plate 211 by welding.

[0068] Specifically, the space truss is formed by a plurality of steel beams connected to each other to form a three-dimensional structure. The nodes of the space truss are fixed to the surrounding plate 211 by welding, which can effectively improve the overall structural strength of the module unit 21. The steel beams can be I-beams, which have good bending resistance. Alternatively, the steel beams can be channel steels, which are low in cost and easy to install.

[0069] On the basis of any one of the above embodiments, with reference to Figure 1 The surrounding plate 211 and the insertion hole 22 are provided with a reinforcing rib plate, and the reinforcing rib plate is symmetrically distributed along the circumference of the insertion hole 22.

[0070] Specifically, the reinforcing ribs are symmetrically distributed along the circumference of the insertion hole 22, and the reinforcing ribs can enhance the structural strength at the insertion hole 22 and prevent the deformation of the surrounding wall 211 when the conical locking piece 31 is inserted. The reinforcing ribs are usually welded by steel plates, and can also be cast steel pieces.

[0071] Optionally, a lifting point is arranged at the insertion hole 22, so that the insertion hole has the function of a lifting point while achieving the fixing function.

[0072] In a specific embodiment provided in the present application, the fixed test field base body 1 includes a first base body 12 and a second base body 13, and the second base body 13 is higher than the first base body 12 to form a stepped structure.

[0073] Specifically, the fixed test field base body 1 includes a first base body 12 and a second base body 13, and the second base body 13 is higher than the first base body 12 to form a stepped structure. This stepped structure can simulate different battlefield environments and increase the diversity of tests. The first base body 12 and the second base body 13 are usually poured with concrete to ensure the stability of the structure.

[0074] On the basis of any one of the above embodiments, with reference to Figure 1 , the second base body 13 is pre-buried with an angle iron 14 along the length direction of the fixed test field base body 1 at the top corner of the side close to the first base body 12.

[0075] Specifically, the second base body 13 is pre-buried with an angle iron 14 along the length direction of the fixed test field base body 1 at the top corner of the side close to the first base body 12. The angle iron 14 is usually made of steel material and can prevent damage to the corner when the armored vehicle climbs.

[0076] In summary, the armored vehicle modular test field provided in the present application directly changes the vertical wall height by increasing or decreasing the number of stacked layers of the modular test device 2 (such as laying 1 layer or 2 layers), which is simple to operate and can accurately meet the height index requirements of different vehicles (such as the differentiated requirements of light and heavy armored vehicles). The modular design realizes flexible adjustment of the vertical wall height, can accurately adapt to the individualized test indexes of different types of armored vehicles (such as light reconnaissance armored vehicles, heavy assault armored vehicles, etc.), solves the problem that the existing fixed-specification vertical wall cannot meet special test requirements, and ensures that the vertical wall passing ability of various vehicles is accurately verified.

[0077] At the same time, the armored vehicle modular test field provided in the present application does not need to build fixed vertical wall facilities for different test indexes, reduces the one-time investment in site construction, reconstruction and equipment purchase; the modules can be reused, and only need to be reorganized and adjusted when facing different test tasks, without the need for additional purchase of a large number of new equipment; at the same time, the maintenance process is simplified, and the long-term operation and maintenance cost is reduced, thereby saving test costs in the whole process.

[0078] The implementation principle of this embodiment is as follows: Through modular design, the height of the vertical wall can be flexibly adjusted according to the testing requirements of different armored vehicles. Each module unit 21 of the modular testing device 2 can be manufactured and transported independently, facilitating installation and disassembly and improving the construction efficiency of the testing range. Simultaneously, the module units 21 can be reused, reducing testing costs. The positioning and connection assembly 3 ensures the stability of the connection between the modular testing device 2 and the fixed testing range base 1, ensuring the safety of the test. Compared with existing technologies, this embodiment solves the problems of existing testing ranges being unable to adapt to diverse testing needs and the excessively high costs of traditional testing methods, providing a more effective means for performance testing of armored vehicles.

[0079] Please refer to Figure 4 This application provides a method for an armored vehicle to pass through a designated obstacle, employing the aforementioned modular test track for armored vehicles. The method specifically includes the following steps:

[0080] S1. Hoist at least one modular test device 2 to a preset position on the fixed test site base 1;

[0081] S2. A fixed connection is achieved by passing the tapered locking member 31 through the insertion hole 22 of the modular test device 2 and the sleeve 11 of the fixed test field base 1.

[0082] S3. Adjust the overall height of the vertical wall by increasing or decreasing the number of stacked layers of the modular test device 2 according to the test requirements;

[0083] S4. Arrange different types of armored vehicles to conduct climbing tests on the fixed test site base 1 and record the test data.

[0084] Specifically, in step S1, during the hoisting process, hoisting equipment such as a crane is required to ensure that the modular test device 2 is accurately placed in the preset position. The hoisting equipment can be a truck crane, which has the advantage of easy mobility, or a tracked crane, which has better stability. In step S2, when inserting the conical locking piece 31, a tool is needed to hammer or press it in to ensure a tight connection. The tool can be a hammer or a hydraulic device. In step S3, if a light reconnaissance armored vehicle needs to be tested, only a few modular units 21 may need to be stacked; if a heavy assault armored vehicle is being tested, more modular units 21 need to be stacked. In step S4, during the test, various sensors and measuring devices are needed to record data such as the armored vehicle's power output, suspension status, and tire friction. The sensors can be pressure sensors, displacement sensors, etc.

[0085] The aforementioned method for armored vehicles to traverse designated obstacles is simple to operate and allows for rapid adjustment of the vertical wall height, meeting the testing requirements of different types of armored vehicles. By recording test data, the ability of armored vehicles to traverse designated obstacles can be accurately evaluated, providing a basis for vehicle technical improvements.

[0086] Based on any of the above embodiments, before arranging different types of armored vehicles to conduct climbing tests on the fixed test range base 1 and recording test data, the test method further includes:

[0087] Interlayer position correction steps: Alignment calibration is performed using the guide reference surface at the bottom of module unit 21 and the limit marks of the lower structure.

[0088] Specifically, the guiding reference surface can be a flat surface at the bottom of the module unit, and the limiting marks can be lines or protrusions engraved on the lower structure. The interlayer position correction step ensures the accuracy of the modular test device stacking and improves the test precision.

[0089] Compared with existing technologies, this embodiment solves the problems that existing test methods cannot adapt to diverse test needs and are too costly, thereby improving test efficiency and quality.

[0090] In some embodiments, the fixed test field base 1 includes a first base 12 and two second bases 13, the second bases 13 being higher than the first base 12, and the two second bases 13 being respectively disposed at both ends of the first base 12 to form a U-shaped structure.

[0091] Specifically, the aforementioned appendix Figure 1 To be continued Figure 3 This is a test range for armored vehicle climbing tests. When two second bases 13 are provided, and the two second bases 13 are located on both sides of the first base 12, it simulates a trench test range. Detailed structure can be found in the appendix. Figure 5 , attached Figure 5 A modular testing ground for armored vehicles to cross trenches.

[0092] Based on the above embodiments, the module unit 21 includes a frame 214, a first connecting rod mounting hole 216, a second connecting rod mounting hole 217, a lifting ring 218, and a skin 219. The frame 214 is provided with a surrounding plate 211, and concrete 212 is poured into the surrounding plate 211. The first connecting rod mounting hole 216 extends along the length direction of the frame 214, and the second connecting rod mounting hole 217 extends along the width direction of the frame 214. The lifting ring 218 is located at the top of the frame 214, and the skin 219 is located at the bottom of the frame 214.

[0093] Specifically, the modular test device 3 consists of a frame 204, a first connecting rod mounting hole 216, a second connecting rod mounting hole 217, a conical locking member 31, a plug-in hole 22, a lifting ring 218, a skin 219, concrete 212, and surface gravel 213. The lifting ring 218 is positioned a certain distance above the concrete surface during hoisting; when stacked, it can be recessed below the concrete surface to avoid interference. Simultaneously, the bottom structure of the frame 214 of the modular test device 3 facilitates forklift loading operations.

[0094] Based on the above embodiment, the insertion hole 22 is provided through the module unit 21 along the height direction of the module unit 21, and the length of the tapered locking member 31 is greater than the length of the insertion hole 22.

[0095] Specifically, before the test, the modular test device 3 needs to be hoisted into the two second bases 13, so that the conical locking part 31 in the modular test device 3 is embedded into the hole of the seamless steel pipe, i.e. the sleeve 11 in the first base 12. This can change the width of the trench in the fixed trench width test field to meet the trench test requirements with different width dimensions. The multiple modular test devices 3 are connected in series in the length direction through the first connecting rod 4, which can enhance the overall structural stability.

[0096] Based on the above embodiments, the positioning connection assembly 3 further includes an adjustable support rod assembly 32, which includes a lead screw 321 and a threaded seat 322 that is threadedly connected to the lead screw 321.

[0097] Specifically, by connecting multiple modular test devices 3 in series in the width direction through the first connecting rod 4, the overall structural stability can be enhanced. The adjustable strut assembly 32 is installed between the modular test device 3 and the fixed trench width test field, which can further improve the stability and safety of the test field.

[0098] This application provides a method for an armored vehicle to pass through a prescribed obstacle, employing the aforementioned modular test range for armored vehicles. The method specifically includes the following steps:

[0099] At least one modular test device 2 is hoisted to a preset position on the fixed test site base 1;

[0100] A fixed connection is achieved by passing a conical locking member 31 through a sleeve 11 of a fixed test field base 1, and an adjustable support assembly 32 is provided between the modular test device 2 and the second base 13.

[0101] The width of the simulated trench can be adjusted by increasing or decreasing the number of columns of the modular test device 2 according to the test requirements;

[0102] Alignment and calibration are performed using the guide reference surface at the bottom of module unit 21 and the limiting marks of the lower structure;

[0103] Different types of armored vehicles were tested on the fixed test site base 1, and the test data were recorded.

[0104] Specifically, during the hoisting process, hoisting equipment such as cranes is required to ensure that the modular test device 2 is accurately placed in the preset position. The hoisting equipment can be a truck crane, which has the advantage of easy mobility, or a tracked crane, which has better stability. When inserting the conical locking piece 31, a tool is needed to hammer or press it in to ensure a tight connection. The tool can be a hammer or a hydraulic device. If a larger trench width needs to be tested, a smaller number of modular test devices 2 are set up in parallel; if a smaller trench span needs to be tested, a larger number of modular devices 2 are set up in parallel. During the test, various sensors and measuring devices are used to record data such as the armored vehicle's power output, suspension status, and tire friction. Sensors can be pressure sensors, displacement sensors, etc., the guiding reference surface can be a flat surface at the bottom of the second type of modular unit, and the limit marks can be lines or protrusions engraved on the lower structure. The inter-layer position correction step ensures the accuracy of the modular test device stacking and improves the test precision.

[0105] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this invention.
