Technical Field
[0001] The utility model relates to the technical field of Hopkinson bar experiments, specifically referring to a solution environment chamber for cooperating with a Hopkinson bar experiment system. Background Art
[0002] The Split Hopkinson Pressure Bar (SHPB, also known as Kolsky bar) experiment system is an important experimental technique in the fields of mechanics and materials, used to study the dynamic mechanical properties of materials under impact loads.
[0003] Traditional Hopkinson bar experiments are carried out in an air environment. However, with the continuous expansion of the field of materials science and the extensive development of materials in diverse application scenarios, the demand for conducting such experiments in a solution environment has become increasingly prominent. In particular, considering that many biological materials are surrounded by biological solutions for a long time under actual use conditions and have complex interactions with the environmental solutions, resulting in significantly different mechanical behaviors of these materials in air and solution environments, and there may also be differences between different solution environments.
[0004] Therefore, it is necessary to design a complete set of solution environment chambers for use with Hopkinson bars to achieve dynamic experiments on materials in a solution environment.
[0005] Specifically, in Hopkinson bar experiments, introducing a solution environment can simulate the solution surrounding conditions that materials may encounter in actual applications, thereby more comprehensively evaluating the mechanical properties of materials. By changing conditions such as the pH value, composition, or temperature of the solution, the effects of these factors on the dynamic mechanical properties of materials can be studied.
[0006] The choice of solution environment mainly depends on specific research purposes and material properties. For example, for biological materials, solution environments such as physiological saline and cell fluid can be selected; for geological materials such as rocks or soils, solution environments simulating groundwater or soil pore fluid can be selected.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0029] As Figure 1 shown, the solution environment box cooperating with the Hopkinson bar experimental system includes a box body 1 for loading the solution. The solution environment box cooperating with the Hopkinson bar experimental system is used in conjunction with the camera system and the detection system; an incident bar 2 and a transmission bar 3 are detachably arranged in the box body 1, and strain gauges in the detection system are arranged on both the incident bar 2 and the transmission bar 3; a perspective window 4 is opened on the box body 1, and the camera system takes pictures of the situation in the box body 1 through the perspective window 4.
[0030] In the present utility model, a solution environment box cooperating with the Hopkinson bar experimental system is provided to prepare a solution environment that meets the experimental requirements for the Hopkinson bar experiment. Before the Hopkinson bar experiment, prepare the corresponding solution according to the experimental requirements to ensure that parameters such as the pH value, composition, and concentration of the solution meet the experimental requirements, and place the bar in the box body 1 to form a simulated solution environment in the box body 1, so as to realize dynamic experiments in the material solution environment, place the test piece under the surrounding of the solution for dynamic experiments, and obtain the experimental data of the dynamic mechanical behavior of the material of the test piece in the solution environment.
[0031] When the present utility model is in use, insert the incident bar 2 and the transmission bar 3 into the box body 1, prepare the corresponding solution in the box body 1 according to the experimental requirements, and ensure that parameters such as the pH value, composition, and concentration of the solution meet the experimental requirements to form a simulated solution environment in the box body 1.
[0032] After setting up the simulated solution environment, place the test piece between the incident bar 2 and the transmission bar 3 so that the test piece is surrounded by the solution to conduct the Hopkinson bar experiment.
[0033] When conducting the Hopkinson bar experiment, under the action of the camera system, record the situation in the box body 1 through the perspective window 4, especially record the deformation process of the test piece through the perspective window 4. Under the action of the detection system, measure the force and deformation of the test piece when it is subjected to an external force through the strain gauge, and then analyze the mechanical properties of the object.
[0034] In the present utility model, the test piece can be fixed by using the friction force between the incident bar and the transmission bar; it can also be placed in the solution by means of lifting and cooperating with a telescopic support to conduct experiments between the incident bar and the transmission bar.
[0035] As an example of this embodiment, the box 1 is a square without a cover. Its specific size can be adjusted according to actual conditions. For a Hopkinson pressure bar test system with a diameter of 20 mm, a box 1 with a side length of 30 cm can be used.
[0036] In some embodiments of the present invention, a first sealing component 6 is provided around the perspective window 4 .
[0037] In detail, in the utility model, a perspective window 4 is provided on the side wall of the box body 1. When in use, the deformation process of the tested piece is recorded through the perspective window 4 in cooperation with the camera. In order to better record the deformation process of the tested piece, the setting direction of the perspective window 4 can be the same as the setting direction of the rod. Preferably, the perspective window 4 is made of a high-definition UV mirror, which can ensure the clear effect of the recording camera.
[0038] A first sealing component 6 is arranged around the perspective window 4 to prevent the liquid in the box body 1 from flowing out of the box body 1. Preferably, the first sealing component 6 is a sealing ring, and the sealing ring is embedded in the periphery of the perspective window 4 to better ensure the sealing effect.
[0039] In some embodiments of the present invention, at least two bearings 15 are provided in the box body 1, and the incident rod 2 and the transmission rod 3 are respectively and correspondingly inserted into at least one of the bearings 15, and the incident rod 2 and the transmission rod 3 are placed on the same horizontal plane.
[0040] In detail, in the present invention, the bearing 15 is mainly used to support the rod, and the rod includes the incident rod 2 and the transmission rod 3. The inner diameter of the bearing 15 is the same as the rod diameter of the rod, which can not only better support the rod, but also prevent the rod from being separated from the bearing 15.
[0041] That is, the end of the rod extends out of the box body 1, and the rod can be supported by the bearing 15 in the box body 1; the part extending out of the box body 1 is provided with the above-mentioned strain gauge.
[0042] In the utility model, the box body 1 can be of different shapes, among which a square shape is preferred. The square box body 1 can facilitate the arrangement of the incident rod 2 and the transmission rod 3, thereby optimizing the overall layout. Moreover, since the four corners of the square box body 1 are relatively flat, the internal space can be maximized, and it can stand firmly and is not easy to tip over or shake. Especially when loading heavy objects, its stability is more prominent, and it also has a certain degree of shock resistance, and the vibration of the solution can be avoided when conducting a Hopkinson pressure bar experiment.
[0043] As an embodiment of this embodiment, through-hole groups are provided on the side walls of the box body 1. The through-hole groups include two through-holes corresponding to each other in position. The incident rod 2 and the transmission rod 3 are respectively inserted into the box body 1 through one through-hole, and second sealing members 7 are provided at the connections between the incident rod 2 and the transmission rod 3 and the box body 1 respectively.

Each rod is supported by the through-hole and the bearing 15 provided on the inner wall of the box body 1, achieving the effect of fixing or restricting the position of the rod in the box body 1.
[0045] Moreover, to prevent the solution in the box body 1 from flowing out, second sealing members 7 are provided at the connections between the rods and the through-holes. The second sealing members can be sealing rings or sealing soft films. Preferably, the sealing soft film is a soft rubber film, which better reduces the influence of the sealing film on the movement of the rods.

The incident rod 2 and the transmission rod 3 are both inserted into the through grooves, and can move in the through grooves to adjust their positions, and third sealing members are provided in the through grooves.

[0048] Among them, the difference between this embodiment and the previous embodiment is that since this embodiment is a through groove, the rod can move in the through groove to adjust its position. During the experiment, the distance between the incident rod 2 and the transmission rod 3 can be adjusted. Moreover, to prevent the solution in the box body 1 from flowing out, third sealing members are provided in the through grooves. The third sealing members can be sealing soft films, which better reduce the influence of the sealing soft films on the movement of the rods; when the distance between the incident rod 2 and the transmission rod 3 is determined, the connection between the rod and the through groove, as well as other positions of the through groove, can be sealed by the sealing soft film.
[0049] It should be noted here that in the above two embodiments, one bearing 15 can be provided for one rod. The bearing 15 is provided on the inner side wall of the box body 1, and the position corresponds to the through-hole or the through groove. When it is set as a through-hole group, it is preferably set at the middle position of the inner side wall. At this time, under the combined action of the bearing 15 and the through-hole or the through groove, the incident rod 2 and the transmission rod 3 are respectively provided on the inner side wall of the box body 1. Multiple bearings 15 are at the same horizontal height.
[0050] In some embodiments of the present invention, a drainage hole 8 is provided at the bottom of the box body 1 , the drainage hole 8 is connected to a drainage pipe 9 , and a drainage valve 10 is provided on the drainage pipe 9 to achieve the effect of discharging the solution in the box body 1 .
[0051] In some embodiments of the utility model, a base assembly is provided under the box body 1, and the base assembly includes an upper base 11 and a lower base 12. The lower base 12 can be placed on a plane. The upper base 11 is connected to the lower base 12 through a plurality of adjustment screws 13, and the box body 1 is placed on the upper base 11.
[0052] In detail, the adjusting screw 13 is used in conjunction with the screw hole of the upper base 11 to adjust the height of the water tank and level the box body 1 so that the height of the two bearings 7 is the same as the rod. The adjusting screw 13 is used to adjust the height and levelness of the box body 1 to ensure that the bearing 7 is horizontal and at the same height as the incident rod 2 and the transmission rod 3.
[0053] In some embodiments of the utility model, a solvent adding mechanism for replenishing solvent into the box 1 is disposed outside the box 1, and the solvent adding mechanism includes at least one solvent bottle 5 disposed outside the box 1, and a scale is disposed on the outer wall of the solvent bottle 5. Solvent is added into the box 1 through the solvent adding mechanism to adjust the pH value of the solution in the box 1.
[0054] Different solvent bottles 5 may contain different types of solvents so that solvents can be added as needed. According to the scale, a certain amount of solvent can be added as needed to adjust and improve the solution environment.
[0055] Furthermore, the detection system includes a plurality of detection components, which are one or more of a strain gauge, an ion concentration meter, a thermometer 14 or a pH monitor.
