[0001] The present application relates to the technical field of test equipment, and in particular to a swing test platform and a swing test system. Background Art

[0002] Sway refers to the periodic angular displacement of a vessel's associated components around their transverse axis when subjected to external forces such as crosswinds and waves. Sway testing is primarily used to simulate the swaying conditions experienced by various mechanical, electrical, and electronic components on ships, submarines, tanks, and mobile artillery. Sway test benches are primarily designed to conduct sway, oscillation, and their combined testing, involving multiple parameters such as static angle, dynamic angle, and acceleration.

[0003] In existing scenarios, the inventors found that most traditional swing test benches use bearing structures. However, the inherent clearance in the bearing structure cannot be eliminated, and the swing friction and wear will accelerate the shortening of the bearing life cycle.

[0004] It can be seen that the mechanical bearing structure used in the existing swing test bench not only has high friction and cannot truly reflect the true modal response of the object being tested, but also has an extremely short lifespan due to mechanical wear. That is, the friction generated by the relative motion of the traditional swing test bench will have a great impact on the accuracy and lifespan. The above-mentioned technical problems need to be solved urgently. Summary of the Invention

[0020] The oil supply port of the first side guide static pressure chamber is used to input the oil into the guide static pressure chamber of the third plane through the corresponding oil channel;

[0021] The oil supply port of the second side guide static pressure chamber is used to input the oil into the guide static pressure chamber of the fourth plane through the corresponding oil channel;

[0022] The bottom load-bearing static pressure chamber oil supply port is used to input the oil into the load-bearing static pressure chamber of the mounting recess through the corresponding oil channel;

[0049] Although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.

[0050] In the description of this specification, the reference terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0051] As described in the background technology, in the prior art, the swing slide usually adopts a mechanical bearing structure. This structure not only has large friction, which makes the provided swing test platform unable to truly reflect the true modal response of the object under test, but also has an extremely short service life due to mechanical wear. In order to solve the above problems, the invention concept of this application was conceived.

[0052] In addition to the above-mentioned understanding of the prior art, the inventors also learned that under certain special working conditions, the test equipment has both swinging relative motion and cannot be affected by additional friction. Therefore, they creatively proposed to achieve this function by using a hydrostatic support swing table. The relative sliding surfaces are filled with a high-rigidity liquid oil film to achieve nearly frictionless relative motion. At the same time, the requirements for reliability are becoming increasingly higher. Various types of relative sliding supports using hydrostatic technology have a series of advantages such as long life, high precision, and large load, and are being increasingly adopted. Specifically in the following embodiments, a swing model using hydrostatic support technology will be further disclosed, including arc surface hydrostatic support and plane hydrostatic support. The arc surface hydrostatic support structure achieves nearly frictionless swinging motion, and the plane hydrostatic support structure achieves nearly frictionless swinging guidance, which will be specifically explained through the following embodiments.

[0053] The first aspect of the present application provides a swing test platform, such as Figure 1-Figure 3 As shown, the swing test platform includes a swing slide 1 and a fixed base 2, wherein:

[0054] The bottom of the swing slide 1 is constructed with a raised arc surface, and the two side surfaces of the raised arc surface are constructed into a first plane 11 and a second plane 12; specifically, the raised arc surface and the first plane 11 and the second plane 12 on its two side surfaces, the bottom of the swing slide 1 is similar to a part of the wheel structure. For example, the bottom of the swing slide 1 can be constructed into at least half of a wheel, the arc surface is at least a semicircular arc surface, and the two sides of the arc surface constitute the first plane 11 and the second plane 12. The swing slide 1 can be constructed into a plane to facilitate an expanded mounting surface.

[0055] Furthermore, the fixed base 2 is configured as a mounting recess that can match the raised arc surface, and the mounting recess is further provided with a third plane (not shown in the figure) parallel to the first plane 11 and a fourth plane (not shown in the figure) parallel to the second plane 12. Specifically, the fixed base 2 can be understood as a mounting recess configured to adapt to the wheel structure; in addition, the mounting recess can also be provided with at least one load-bearing static pressure cavity that can be connected to an external oil supply interface or an external oil supply device. The at least one load-bearing static pressure cavity can include three load-bearing static pressure cavities, such as Figure 3 The first load-bearing static pressure chamber 21, the second load-bearing static pressure chamber 22 and the third load-bearing static pressure chamber 23 are shown; through the above-mentioned load-bearing static pressure chamber, the external oil supply equipment can introduce oil into the corresponding load-bearing static pressure chamber on the mounting recess, so that at least the gap between the raised arc surface and the mounting recess can be filled with oil, and the oil on the corresponding load-bearing static pressure chamber can support the raised arc surface. In addition, under the guidance of the first plane 11 and the parallel third plane, and the second plane 12 and the parallel fourth plane, the raised arc surface can slide on the mounting recess along the guiding direction of the mutual planes.

[0056] In the above embodiment, the bottom of the swing slide 1 is constructed as a convex arc surface, and the first plane 11 and the second plane 12 are constructed on both sides of the arc surface, and the fixed base 2 is constructed as a mounting recess that can match the convex arc surface, and the mounting recess is further provided with a third plane parallel to the first plane 11, a fourth plane parallel to the second plane 12, and at least one load-bearing static pressure cavity that can be connected to an external oil supply interface or an external oil supply device, so that a guide structure is formed between the mutually parallel planes, that is, the first plane 11 constructed on both sides of the arc surface. 1 and the second plane 12 form a guiding structure with the first plane 11 and the second plane 12 constructed on the mounting recess, thereby enabling the swing slide 1 to slide guidedly on the swing slide 1 after oil is input into the mounting recess. It can be understood that by filling the arc surface and the mounting recess with oil, the gap seal with full oil film contact replaces the conventional sealing ring and mechanical guide. While achieving the guiding and sealing functions of the conventional sealing ring, it also achieves nearly frictionless relative motion, realizes the advantageous performance of the swing test platform such as high precision and high load, and improves the service life of the swing test platform. In addition, the innovative research of this low-friction, high-load hydrostatic swing slide 1 will play a crucial role in simulating the product's real-world operating conditions and determining the product's adaptability and structural integrity to withstand the rigors of swing operation.

[0057] In one embodiment, the third plane and the fourth plane are each provided with at least one guide static pressure cavity. Figure 3 and Figure 4 As shown, the third plane may include two pilot static pressure chambers, namely, a first pilot static pressure chamber 24 and a second pilot static pressure chamber 25. The fourth plane may include two pilot static pressure chambers, namely, a third pilot static pressure chamber 26 and a fourth pilot static pressure chamber 27. Specifically, the first pilot static pressure chamber 24 and the second pilot static pressure chamber 25 may be arranged symmetrically with the third pilot static pressure chamber 26 and the fourth pilot static pressure chamber 27, so that the oil can be more evenly filled in the gaps between the planes. It should be noted that the above embodiment is for illustrative purposes only and does not actually limit the number of pilot static pressure chambers. The configuration can be adjusted according to actual scenarios.

[0058] In the above embodiment, by configuring a guide static pressure cavity corresponding to the plane of the side, it is possible to realize the flat static pressure support on the side while realizing the bottom static pressure support of the above embodiment. In this way, the arc surface static pressure support structure can realize nearly frictionless swinging motion, and the flat static pressure support structure can realize nearly frictionless swinging guidance, thereby further improving the test performance and service life of the swing test platform.

[0059] In one embodiment, grooves (not shown in the figure) may be further provided on the mounting recess, the third plane and the fourth plane of the above embodiment, respectively. The groove of the mounting recess forms a load-bearing static pressure cavity, and the grooves of the third plane and the fourth plane form corresponding guide static pressure cavities; wherein each groove is provided with an oil channel that can be connected to an external oil supply interface or an external oil supply device.

[0060] In the above embodiment, corresponding static pressure chambers are formed by configuring corresponding grooves, and each groove is provided with an oil channel that can be connected to an external oil supply interface or an external oil supply device, so that the oil can be filled in the corresponding groove, so that even if the external oil supply fails, the swing test platform can still maintain normal operation, thereby improving the durability and flexibility of the use of the swing test plane.

[0061] In one embodiment, Figure 1 As shown, the swing test platform can also include a plurality of slit throttles 3, each slit throttle 3 is provided on the corresponding load-bearing static pressure chamber and the guide static pressure chamber, and the slit throttle 3 is used to damp the oil pressure input into the corresponding static pressure chamber to improve the stability of the swing test platform; in addition, the swing test platform also includes a plurality of pressure sensors 5, each pressure sensor 5 is provided on the corresponding load-bearing static pressure chamber and the guide static pressure chamber, and the pressure sensor 5 is used to detect the cavity pressure of the corresponding static pressure chamber, so that real-time monitoring and timely adjustment can be performed according to the corresponding pressure.

[0062] It should be noted that the multiple slit throttles 3 and the multiple pressure sensors 5 included in the above embodiment can also be configured separately, as described in the following embodiment, without specific limitation, and can be selected and configured according to actual scenarios.

[0063] In one embodiment, Figure 1 As shown, the swing test platform may further include a plurality of slit throttles 3, each slit throttle 3 being provided on the corresponding load-bearing static pressure chamber and guide static pressure chamber.

[0064] Alternatively, in one embodiment, Figure 1 As shown, the rocking test platform may further include a plurality of pressure sensors 5 , each of which is provided on a corresponding bearing static pressure cavity and a guide static pressure cavity.

[0065] In the above embodiment, by configuring the swing test platform with corresponding slit restrictors 3 and pressure sensors 5, or a separate slit restrictor 3, or a separate pressure sensor 5, the swing test platform can be made more stable and durable.

[0066] In one embodiment, Figure 1As shown, a mounting surface is further provided on the swing slide 1, and the swing test platform further comprises an inclination measuring sensor 4 mounted on the mounting surface, and the inclination measuring sensor 4 is used to measure the real-time swing angle of the swing test platform.

[0067] In the above embodiment, by disposing the inclination angle measurement sensor 4 on the installation surface of the swing test platform, real-time monitoring can be performed based on the real-time swing angle of the swing test platform.

[0068] In one embodiment, the mounting recess may be provided with a plastic coating. The plastic coating can enhance the anti-oxidation performance of the mounting recess, thereby further increasing the service life of the rocking test platform.

[0069] In one embodiment, Figure 5 As shown, the fixed base 2 is further provided with a first side guide static pressure chamber oil supply port connected to the guide static pressure chamber of the third plane, a second side guide static pressure chamber oil supply port connected to the guide static pressure chamber of the fourth plane, and a bottom load-bearing static pressure chamber oil supply port 8 connected to the load-bearing static pressure chamber, wherein:

[0070] The first side guide static pressure chamber oil supply port is used to input oil into the guide static pressure chamber of the third plane through the corresponding oil channel. The first side can be Figure 5 The left side of the first side guide static pressure chamber oil supply port is Figure 5 The left side of the static pressure chamber guide oil supply port 7; the second side of the static pressure chamber guide oil supply port for the oil through the corresponding oil channel, the oil input into the fourth plane of the static pressure chamber, the second side can be Figure 5 The right side of the second side guide static pressure chamber oil supply port is Figure 5 The right-side pilot static pressure chamber oil supply port 10 is located in the mounting recess; the bottom load-bearing static pressure chamber oil supply port 8 is used to supply oil to the load-bearing static pressure chamber in the mounting recess through corresponding oil channels. Furthermore, based on the above embodiment, each recess is provided with an oil channel capable of communicating with an oil supply device. The first-side pilot static pressure chamber oil supply port, the second-side pilot static pressure chamber oil supply port, and the bottom load-bearing static pressure chamber oil supply port 8 can all communicate with an external oil supply device through corresponding oil channels.

[0071] In the above embodiment, by designing all oil ports on the fixed base 2, the influence of the vibrating hydraulic pipeline on the actual swing posture of the sliding end can be reduced or even avoided, thereby further improving the stability of the swing test platform; in addition, it can also facilitate the external oil supply equipment to input the oil into the corresponding static pressure chamber through the corresponding oil port, so as to improve the flexibility of use.

[0072] In one embodiment, Figure 5 As shown, a gap oil drain port 9 is further provided on the fixed base 2, and the gap oil drain port 9 is used to drain the gap oil leakage of the corresponding static pressure cavity, so that the intermittent oil leakage can be adjusted in real time.

[0073] In addition, an oil return groove 28 can be processed inside the fixed base 2, and the oil return groove 28 is used to collect the oil leaked from the load-bearing static pressure chamber and / or the guide static pressure chamber, so as to ensure that the gap oil does not leak out without any mechanical sealing ring.

[0074] In one embodiment, Figure 4 and Figure 5 As shown, the interior of the swing slide 1 is constructed into a cavity structure A. Specifically, four symmetrical cavity structures A can be constructed on the swing slide 1. While reducing the weight of the swing slide 1 through the corresponding symmetrical cavity structures A, the original basic structural strength can be maintained, and installation and expansion can be performed on the corresponding cavity structures A to improve the flexibility of the use of the swing test platform.

[0075] In one embodiment, Figure 5 As shown, the fixed base 2 can also be configured with a corresponding fixed installation structure. For example, by configuring four fixed installation structures on the two side surfaces respectively, the fixed base 2 can be fixedly installed on the test basic platform through 8 mounting screws 6 to improve the flexibility and scalability of actual use.

[0076] The following is a complete working description of the above embodiment. After the external oil supply device is turned on, the first high-pressure oil enters the load-bearing static pressure chamber through the bottom load-bearing static pressure chamber oil supply port 8. The load-bearing static pressure chambers are respectively the first load-bearing static pressure chamber 21, the second load-bearing static pressure chamber 22, and the third load-bearing static pressure chamber 23. Among them, the second load-bearing static pressure chamber 22 is the main load-bearing chamber, and the load-bearing direction is radially upward along the arc surface. The first load-bearing static pressure chamber 21 and the third load-bearing static pressure chamber 23 are auxiliary load-bearing static pressure chambers. The two load-bearing static pressure chambers are arranged symmetrically, and the combined load-bearing direction is radially upward along the arc surface. After the oil flows through the slit throttle 3, a pressure drop is generated, which suspends the arc surface swing slide 1 above the fixed base 2. At this time, the arc surface swing slide 1 can swing around the center line of the arc surface. When the hydrostatic swing slide 1 is subjected to a load directed radially downward along the arc surface, the relative sliding surface gap becomes smaller, the pressure in the hydrostatic cavity increases, and the bearing capacity increases, thereby achieving dynamic balance of the hydrostatic swing slide 1 in the radial direction of the arc surface. When the load decreases, the relative sliding surface gap becomes larger, so that more hydrostatic oil flows away. When the amount of oil flowing away per unit time is greater than the amount of oil introduced from the slit throttle 3, the pressure in the hydrostatic cavity decreases, and the dynamic balance of the hydrostatic swing slide 1 in the radial direction of the arc surface is achieved again.

[0077] Furthermore, the second high-pressure oil enters the guide static pressure chambers through the left guide static pressure chamber oil supply port 7 and the right guide static pressure chamber oil supply port 10. The guide static pressure chambers are the first and second guide static pressure chambers 24 and 25 on the third plane, and the third and fourth guide static pressure chambers 26 and 27 on the fourth plane, totaling two groups. Each group of guide static pressure chambers is used in pairs. Hydraulic oil of the same pressure produces the same pressure drop after passing through the slit restrictor 3 with the same damping, and the pressure entering the guide static pressure chambers is equal. Guide static pressure chambers of the same size generate the same load. The two groups of guide static pressure chambers achieve nearly frictionless guidance in the swing direction, ensuring that the arc-surface swing slide 1 is suspended on the fixed base 2. When the arc surface swing slide 1 is subjected to a lateral load, the throttling gap of the guide static pressure chamber on the loading side becomes larger, so that more static pressure oil flows away. When the amount of oil flowing away per unit time is greater than the amount of oil introduced from the slit throttle 3, the pressure in the static pressure chamber decreases, the guide static pressure throttling gap on the other side becomes smaller, the pressure in the static pressure chamber increases, and the bearing capacity increases, thereby achieving dynamic balance of the static pressure swing slide 1 in the lateral direction and realizing a nearly frictionless swing state of the static pressure swing slide 1.

[0078] In addition, the static pressure support leakage oil is collected at the gap oil drain port 9 by the internal oil return groove 28 of the fixed base 2 and returned to the oil tank.

[0079] A second aspect of the present application provides a swing test system, wherein the swing test system includes the swing test platform in any embodiment of the first aspect.

[0080] Based on the many advantages of the swing test platform in the above-mentioned first embodiment, the swing test system also has many advantages. To avoid redundancy, they will not be elaborated here.

[0081] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.

[0082] The above specific embodiments of the present invention do not constitute a limitation on the scope of protection of the present invention.
