[0037] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. 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.

[0038] The honeycomb sandwich vibration isolation base, the adjusting system and method of the honeycomb sandwich vibration isolation base provided by the embodiments of the present application will be described below with reference to the drawings.

[0039] Figure 1 is a structural schematic diagram of a honeycomb sandwich vibration isolation base provided by an embodiment of the present application. As shown in Figure 1 the honeycomb sandwich vibration isolation base provided by the embodiment of the present application comprises an upper rib plate 110, a honeycomb core 120 and a lower rib plate 130. The honeycomb core 120 is arranged between the upper rib plate 110 and the lower rib plate 130, and the honeycomb core 120 comprises a plurality of regular hexagonal honeycomb cells.

[0040] In actual execution, the honeycomb sandwich vibration isolation base is composed of two layers of high-strength rib plates and a thick and extremely light honeycomb core layer sandwiched in the middle. Generally, the honeycomb core 120 is bonded and formed with the upper rib plate 110 and the lower rib plate 130 after processing, and the honeycomb core 120 is between the upper rib plate 110 and the lower rib plate 130.

[0041] In the embodiment of the present application, the honeycomb core 120 can be a composite material, such as glass steel, rubber, carbon fiber, etc. In order to further increase the structural impedance, a damping liquid is poured into the honeycomb core gap, which can effectively improve the structural impedance and consume part of the energy generated due to structural vibration when deforming, thereby inhibiting the vibration of the structure.

[0042] The upper rib plate 110 can be a thin panel with high strength, which can be a high-strength composite material, such as a high-strength carbon fiber composite material, a high-strength resin composite material, a high-strength nanocomposite material, etc. The size of the upper rib plate 110 can be set according to actual conditions, which is not specifically limited here

[0043] The lower rib plate 130 can be a thin panel with high strength, which can be a high-strength composite material, such as a high-strength carbon fiber composite material, a high-strength resin composite material, a high-strength nanocomposite material, etc. The size of the lower rib plate 130 can be set according to actual conditions, which is not specifically limited here

[0044] Figure 2 is a schematic diagram of a honeycomb core structure provided by an embodiment of the present application, as Figure 2 shown, the honeycomb core 120 includes a plurality of regular hexagonal honeycomb cells, which are surrounded by a plurality of cell walls with a certain thickness. The honeycomb cells are filled with damping liquid. The size and number of the honeycomb cells can be set according to actual conditions, which is not specifically limited here

[0045] Figure 3 is a schematic diagram of a rib plate structure, Figure 3 The rib plate in the rib plate structure can be the upper rib plate 110 or the lower rib plate 130. The rib plate is a thin panel with high strength, which can be a high-strength composite material, such as a high-strength carbon fiber composite material, a high-strength resin composite material, a high-strength nanocomposite material, etc.

[0046] In some embodiments, at least one cell wall of any honeycomb cell is provided with a through hole, so that all the honeycomb cells in the honeycomb core are connected to each other, and the damping liquid in the honeycomb core flows.

[0047] In an embodiment of the present application, the cell walls of the honeycomb cells are perforated, which serves to realize the interconnection of the honeycomb cells, so that the damping liquid in the honeycomb core 120 can flow. The through holes in the embodiment of the present application are designed to ensure the firmness and connectivity of the honeycomb sandwich vibration isolation base.

[0048] In actual implementation, the number, size and shape of the through holes can affect the firmness of the honeycomb sandwich vibration isolation base. The more the number of through holes, the larger the size of the through holes, the less firm the honeycomb sandwich vibration isolation base.

[0049] The shape of the through hole can be rectangular, circular, elliptical or other shapes. The number of through holes can be at least the number of through holes that can connect all the honeycomb cells in the honeycomb core to each other, and the size of the through hole can be set according to actual conditions, which is not specifically limited here.

[0050] Figure 4is one of the honeycomb core through hole design schematic diagrams provided by the embodiment of the present application. As shown in Figure 4 The structure in the dashed box 410 is used to indicate the hole wall without a through hole, and the structure in the dashed box 420 is used to indicate the hole wall with a through hole.

[0051] It can be understood that, Figure 4 The hole wall same as the structure in the dashed box 410 is the hole wall without a through hole, and the hole wall same as the structure in the dashed box 420 is the hole wall with a through hole.

[0052] It can be seen that, Figure 4 In the embodiment of the present application, all the honeycomb cells in the honeycomb core are interconnected, and the damping liquid can flow in the honeycomb core. Of course, the hole wall without a through hole can be further designed with a through hole according to actual needs, Figure 4 The through hole design in the embodiment of the present application is only used as an example and is not specifically limited herein.

[0053] In the embodiment of the present application, the through hole on the hole wall is arranged at a position close to the lower rib plate, which is convenient for the damping liquid to flow.

[0054] Figure 5 is the second honeycomb core through hole design schematic diagram provided by the embodiment of the present application. Taking any hole wall of any honeycomb cell in the honeycomb core as an example, as shown in Figure 5 A circular through hole 510 is arranged on the hole wall 530. The through hole 510 is arranged at a position close to the lower rib plate 520.

[0055] In some embodiments, the height h of the through hole 510 is not more than 1 / 8 of the height H of the honeycomb cell, and the hole diameter of the through hole 510 is not more than 1 / 5 of the width D of the honeycomb cell.

[0056] The honeycomb sandwich vibration isolation base provided by the embodiment of the present application realizes the interconnection of all the honeycomb cells by arranging a certain number of through holes on the hole walls of the honeycomb cells in the honeycomb core, so that the damping liquid in each honeycomb core can flow and can quickly reduce vibration, thereby improving the use performance of the honeycomb sandwich vibration isolation base.

[0057] Figure 6 is a structure schematic diagram of the adjusting system of the honeycomb sandwich vibration isolation base provided by the embodiment of the present application. As shown in Figure 6 The honeycomb sandwich vibration isolation base provided by the embodiment of the present application comprises the honeycomb sandwich vibration isolation base 610, the damping liquid adjusting device 620 and the vibration sensor in the above embodiment.

[0058] Figure 7 is a structure schematic diagram of the vibration sensor provided by the embodiment of the present application. As shown in Figure 7As shown, the vibration sensor 710 is arranged on the lower rib plate 720 of the honeycomb sandwich vibration isolation base 610, preferably, the vibration sensor 710 is arranged at the center of the lower rib plate 720 of the honeycomb sandwich vibration isolation base 610.

[0059] In actual implementation, the damping liquid adjusting device 620 is connected with the honeycomb core through a pipeline to realize the connection with the honeycomb sandwich vibration isolation base 610.

[0060] The damping liquid adjusting device 620 is used to adjust the total amount of damping liquid in the honeycomb core, and the vibration sensor 710 is used to monitor the vibration intensity of the target equipment after passing through the honeycomb sandwich vibration isolation base.

[0061] In actual implementation, since the total amount of damping liquid in the honeycomb sandwich vibration isolation base 610 has an important influence on the vibration isolation effect, the damping liquid adjusting device 620 can adjust the total amount of damping liquid in the honeycomb core according to specific needs, for example, the total amount of damping liquid in the honeycomb core can be increased or decreased.

[0062] It should be noted that the target equipment is the object of the honeycomb sandwich vibration isolation base 610, for example, a ship mechanical equipment or an aerospace vehicle, etc. The vibration sensor 710 can monitor the vibration intensity V of the target equipment after passing through the honeycomb sandwich vibration isolation base 610 in real time.

[0063] In the embodiment of the application, the total amount of damping liquid in the honeycomb core is adjusted by the damping liquid adjusting device 620, and then the vibration intensity V corresponding to different total amounts of damping liquid can be recorded, that is, the minimum vibration intensity V min corresponding to the total amount of damping liquid can be obtained, which can indicate that the honeycomb core is adjusted to the minimum vibration intensity V min corresponding to the total amount of damping liquid, and the optimal vibration isolation effect can be obtained.

[0064] The adjusting system of the honeycomb sandwich vibration isolation base provided in the embodiment of the application adjusts the total amount of damping liquid in the honeycomb core by the damping liquid adjusting device, and combines the vibration intensity of the target equipment after passing through the honeycomb sandwich vibration isolation base detected by the vibration sensor, to realize the flexible adjustment of the use performance of the honeycomb sandwich vibration isolation base and effectively improve the vibration isolation effect.

[0065] In some embodiments, the damping liquid adjusting device 620 comprises a first centrifugal pump, a first valve, a second centrifugal pump, a second valve, a liquid storage tank and an industrial computer.

[0066] The honeycomb core is connected with the first centrifugal pump and the second centrifugal pump respectively; the first centrifugal pump is connected with the first valve, and the second centrifugal pump is connected with the second valve; the first valve and the second valve are both connected with the liquid storage tank.

[0067] The industrial computer is used for controlling the on-off states of the first centrifugal pump, the first valve, the second centrifugal pump and the second valve; and the liquid storage tank is used for determining the total amount of the damping liquid.

[0069] As shown in Figure 6 , the first centrifugal pump can be No. 1 centrifugal pump, the first valve can be No. 1 valve, the second centrifugal pump can be No. 2 centrifugal pump, and the second valve can be No. 2 valve.

[0070] The honeycomb core in the honeycomb sandwich vibration isolation base 610 is connected with the first end of the No. 1 centrifugal pump and the first end of the No. 2 centrifugal pump through pipelines, the second end of the No. 1 centrifugal pump is connected with the first end of the No. 1 valve through a pipeline, the second end of the No. 2 centrifugal pump is connected with the first end of the No. 2 valve through a pipeline, and the second end of the No. 1 valve and the second end of the No. 2 valve are both connected with the liquid storage tank through pipelines.

[0071] The industrial computer is connected with the No. 1 centrifugal pump, the No. 2 centrifugal pump, the No. 1 valve and the No. 2 valve through communication or electricity, and the connection mode is not limited in the embodiment. The industrial computer is used for controlling the on-off states of the first centrifugal pump, the first valve, the second centrifugal pump and the second valve, so that the total amount of the damping liquid in the inside of the honeycomb core can be controlled.

[0072] A liquid level sensor is arranged in the liquid storage tank, the total amount T of the damping liquid in the inside of the honeycomb core is calculated in real time, and the total amount T of the damping liquid in the inside of the honeycomb core is the total amount of the damping liquid preset for the target device minus the total amount of the damping liquid in the inside of the liquid storage tank.

[0073] The adjusting system of the honeycomb sandwich vibration isolation base provided in the embodiment can adjust the on-off states of the two centrifugal pumps and the two valves through the industrial computer, and the total amount of the damping liquid obtained in the liquid storage tank, and the total amount of the damping liquid in the inside of the honeycomb core is calculated in real time, so that the total amount of the damping liquid in the inside of the honeycomb core can be accurately controlled.

Referring to Figure 8 , the adjusting method of the honeycomb sandwich vibration isolation base provided by the embodiment of the present application comprises:

[0080] Step 810: in the case that the target device is in a target operation condition, the total amount of the damping liquid in the honeycomb core of the honeycomb sandwich vibration isolation base is adjusted to the optimal damping liquid amount corresponding to the target operation condition.

[0081] It should be noted that the execution subject of the adjusting method of the honeycomb sandwich vibration isolation base provided by the embodiment of the present application can be an electronic device, a component in the electronic device, an integrated circuit, or a chip.

Exemplarily, the mobile electronic device can be a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), etc., and the non-mobile electronic device can be a server, a network attached storage (NAS), a personal computer (PC), a television (TV), a teller machine, or a self-service machine, etc., and the present application is not limited in this regard.

[0082] In the following, the technical solution of the present application will be described in detail by taking the computer executing the adjusting method of the honeycomb sandwich vibration isolation base provided by the embodiment of the present application as an example.

[0083] Since the traditional honeycomb sandwich vibration isolation base is often designed for a specific working condition of the ship mechanical equipment, that is, the honeycomb sandwich vibration isolation base has good vibration isolation performance for the specific working condition of the ship mechanical equipment after the design and manufacturing are completed. With the trend of complex ship sailing working conditions, the traditional honeycomb sandwich vibration isolation base gradually cannot meet the multi-working condition operation requirements of the ship mechanical equipment. Therefore, it is urgent to design a kind of adjusting method which can adapt to the multi-working condition operation for the honeycomb sandwich vibration isolation base.

[0084] In view of the multi-working condition operation requirements of the honeycomb sandwich vibration isolation base, the adjusting method of the honeycomb sandwich vibration isolation base is provided in the embodiment of the present application:

[0085] (1) The honeycomb sandwich vibration isolation base is designed to be perforated near the lower rib plate, so as to realize the interconnection of all honeycomb cells in the honeycomb core, and the damping liquid in the honeycomb core can flow;

[0086] (2) A set of damping liquid adjusting device is arranged for the honeycomb sandwich vibration isolation base, including a centrifugal pump, a valve, a pipeline, a liquid storage tank and an industrial computer, and the total amount of the damping liquid in the honeycomb core can be adjusted according to specific needs;

[0087] (3) A vibration sensor is arranged at the center of the lower rib plate of the honeycomb sandwich vibration isolation base, so as to monitor the vibration intensity V of the target equipment after passing through the honeycomb sandwich vibration isolation base in real time, and a liquid level sensor is arranged in the liquid storage tank of the damping liquid adjusting device, so as to calculate the total amount T of the damping liquid in the honeycomb core in real time;

[0088] (4) Since the total amount of the damping liquid in the honeycomb sandwich vibration isolation base has an important influence on the vibration isolation effect, for a certain working condition of the target equipment, the total amount T of the damping liquid in the honeycomb core is adjusted by the damping liquid adjusting device, and the vibration intensity V of the lower rib plate of the honeycomb sandwich vibration isolation base at each adjusting position is recorded on the industrial computer, so that the minimum vibration intensity V min Corresponding to the total amount of the damping liquid, the optimal damping liquid amount T z , can produce the optimal vibration isolation effect on the target equipment under this working condition;

[0089] (5) After the working condition of the target equipment changes each time, the damping liquid adjusting device can be adjusted to the optimal damping liquid amount T z , so that the honeycomb sandwich vibration isolation base can produce the optimal vibration isolation effect on the target equipment under the current working condition.

[0090] In step 810, the target equipment is the object of the honeycomb sandwich vibration isolation base, for example: ship mechanical equipment or aerospace vehicle, etc.

[0091] Before step 810, the optimal damping liquid amount needs to be determined. The optimal damping liquid amount is determined by the following method:

[0092] Adjust the total amount of damping fluid inside the honeycomb core based on the target operating conditions;

[0093] Determine the vibration intensity corresponding to different total amounts of damping fluid, and determine the total amount of damping fluid corresponding to the minimum vibration intensity as the optimal amount of damping fluid for the target operating condition.

[0094] Taking marine machinery as an example, since the total amount of damping fluid inside the honeycomb sandwich vibration isolation base has a significant impact on its vibration isolation effect, the total amount T of damping fluid inside the honeycomb core is adjusted by a damping fluid adjustment device according to the target operating conditions of the marine machinery. Based on the adjustable precision of the damping fluid adjustment device, there are n adjustment levels: T1, T2, T3, ..., T... n The honeycomb sandwich vibration isolation base is adjusted according to n adjustment levels using a damping fluid adjustment device. The vibration intensity V1, V2, V3, ..., V at the lower stiffening plate of the honeycomb sandwich vibration isolation base is recorded by the industrial control computer at each adjustment level by the vibration sensor. n Then the minimum vibration intensity V min Corresponding adjustment gear T z (1≤z≤n) is the optimal gear, which is the optimal damping fluid volume corresponding to the target operating condition, and can produce the best vibration isolation effect for the ship's mechanical equipment under this operating condition.

[0095] Understandably, after each change in the operating conditions of the ship's machinery, the damping fluid adjustment device can adjust to the adjustment level T corresponding to the optimal damping fluid volume according to the above steps. z This enables the honeycomb sandwich vibration isolation base to produce the optimal vibration isolation effect for ship machinery and equipment under current operating conditions, effectively improving the ship's working environment.

[0096] The adjustment method of the honeycomb sandwich vibration isolation base provided by the present invention adjusts the total amount of damping fluid inside the honeycomb core based on the target operating conditions of the target equipment, and can adjust it to the optimal amount of damping fluid to obtain the optimal vibration isolation effect and effectively improve the working environment conditions of the target equipment.

[0097] The adjustment device for the honeycomb sandwich vibration isolation base provided in the embodiments of the present invention will be described below. The adjustment device for the honeycomb sandwich vibration isolation base described below can be referred to in correspondence with the adjustment method for the honeycomb sandwich vibration isolation base described above.

[0100] The adjusting module 910 is configured to adjust the total amount of damping liquid inside the honeycomb core of the honeycomb sandwich vibration isolation base to an optimal damping liquid amount corresponding to the target operation condition when the target device is in the target operation condition.

[0101] In some embodiments, the optimal damping liquid amount is determined by the following method:

[0102] Based on the target operation condition, the total amount of damping liquid inside the honeycomb core is adjusted.

[0103] The vibration intensity corresponding to different total amounts of damping liquid is determined, and the total amount of damping liquid corresponding to the minimum vibration intensity is determined as the optimal damping liquid amount corresponding to the target operation condition.

[0104] The adjusting device of the honeycomb sandwich vibration isolation base provided by the application can adjust the total amount of damping liquid inside the honeycomb core based on the operation condition of the target device, and can be adjusted to the optimal damping liquid amount, so that the optimal vibration isolation effect is obtained, and the working environment condition of the target device is effectively improved.
