Abstract
Description
Technical Field
[0001] This invention relates to the field of vibration control technology, and in particular to a vibration damping base and an adjustment system for the vibration damping base. Background Technology
[0002] With the development of larger and faster ships, the vibration and noise intensity of ship machinery and equipment has increased significantly. Meanwhile, the requirements for ship quietness and comfort are also becoming increasingly stringent, making vibration and noise a crucial indicator that cannot be ignored in ship design and manufacturing. Ship radiated noise primarily originates from the vibration of various mechanical equipment on the hull. Currently, measures to control ship vibration and noise mainly focus on isolating the vibration of mechanical equipment, such as through structural optimization design, the installation of vibration isolation systems, and the use of vibration-damping steel and materials. The aim is to reduce or isolate the further transmission of vibration to surrounding structures, thereby reducing vibration and radiated noise throughout the entire ship. Therefore, based on the needs of ship quietness development, it is essential to improve the vibration isolation performance of the vibration isolation base to effectively enhance the ship's working environment conditions.
[0003] Traditional vibration damping bases are often designed for specific operating conditions of marine machinery and equipment. In other words, once designed and manufactured, the base only provides good vibration damping performance for that specific type of equipment. As ship navigation conditions become increasingly complex, traditional bases are gradually becoming unable to meet the multi-condition operating requirements of marine machinery and equipment.
[0004] Therefore, there is an urgent need to design a vibration-damping base that can adapt to multiple operating conditions for the equipment base. Summary of the Invention

[0017] The correspondence between the multiple adjustment gears of the drive motor and the vibration intensity sensed by the vibration sensor after passing through the vibration damping base is determined as the relationship between gear and vibration intensity;
[0018] Based on the relationship between the adjustment level and the vibration intensity, the adjustment level corresponding to the minimum vibration intensity is selected as the most suitable adjustment level.
[0019] In some embodiments, the drive motor is fixedly connected to the bracket, and the bracket is fixedly attached to the upper surface of the lower stiffener; the upper surface of the lower stiffener is the surface in contact with the shock-absorbing interlayer.
[0020] In some embodiments, the drive motor is fixedly connected to the bracket, and the bracket is fixedly attached to the lower surface of the upper stiffening plate; the lower surface of the upper stiffening plate is the surface in contact with the shock-absorbing interlayer.

Detailed Implementation
[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0036] Figure 1 This is a schematic cross-sectional view of the vibration damping base provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the vibration damping base includes: a damping interlayer 130, an upper stiffening plate 110, and a lower stiffening plate 120; the damping interlayer 130 has a hexahedral structure and is disposed between the upper stiffening plate 110 and the lower stiffening plate 120, and the interior of the damping interlayer 130 is filled with micro elastic rubber particles; one side of the hexahedral structure of the damping interlayer 130 perpendicular to the upper stiffening plate 110 and the lower stiffening plate 120 is a movable sealing surface, and the other sides are fixed sealing surfaces; the movable sealing surface is used to adjust to the position that minimizes the vibration intensity after passing through the vibration damping base according to the ship's navigation conditions.
[0037] In actual implementation, the vibration damping base consists of two layers of high-strength stiffening plates and a hexahedral damping interlayer sandwiched in the middle. Typically, the hexahedral damping interlayer 130 has two faces that are in direct contact with the upper stiffening plate 110 and the lower stiffening plate 120, and these two faces are immovable, that is, they are fixed to the lower surface of the upper stiffening plate 110 and the upper surface of the lower stiffening plate 120, respectively.
[0038] In this embodiment of the invention, the shock-absorbing interlayer 130 is filled with micro-elastic rubber particles, which have the characteristics of moderate elasticity, anti-slip, good water permeability, wear resistance, flame retardancy, non-toxicity, non-radioactivity, anti-aging, and long service life. In the initial state, the position of the movable sealing plate of the shock-absorbing interlayer 130 allows the micro-elastic rubber particles filled inside the shock-absorbing interlayer 130 to remain in a natural state, that is, not compressed.
[0039] The top stiffener 110 can be a thin panel with high strength, which can be a high-strength composite material, such as high-strength carbon fiber composite material, high-strength resin composite material, high-strength nanocomposite material, etc. The size of the top stiffener 110 can be set according to the actual situation and is not specifically limited here.
[0040] The lower stiffener 120 can be a thin panel with high strength, which can be a high-strength composite material, such as high-strength carbon fiber composite material, high-strength resin composite material, high-strength nanocomposite material, etc. The size of the lower stiffener 120 can be set according to the actual situation and is not specifically limited here.
[0041] The six sealing surfaces of the shock-absorbing interlayer 130 can also be made of the same material as the upper stiffening plate 110.
[0042] Figure 2 This is a three-dimensional schematic diagram of the vibration damping base structure provided in this embodiment of the invention; the movable sealing surface 131 in the hexahedral structure of the vibration damping interlayer 130 can move horizontally between the upper stiffening plate 110 and the lower stiffening plate 120; the upper fixed sealing surface 133 in the hexahedral structure of the vibration damping interlayer 130 is fixed to the lower surface of the upper stiffening plate 110; the lower fixed sealing surface 134 in the hexahedral structure of the vibration damping interlayer 130 is fixed to the upper surface of the lower stiffening plate 120; the left fixed sealing surface 132 in the hexahedral structure of the vibration damping interlayer 130 is distributed parallel to the movable sealing surface 131 in the hexahedral structure of the vibration damping interlayer 130; the vibration damping interlayer 130 is filled with micro elastic rubber particles, which can be of any shape, such as spheres, cubes, or other irregular shapes, and are not specifically limited here.
[0043] In the hexahedral structure of the damping interlayer 130, the movable sealing surface 131 moves horizontally between the upper stiffener 110 and the lower stiffener 120 after being subjected to external force, causing the volume of the damping interlayer 130 to change. This causes the micro elastic rubber particles filled inside the damping interlayer 130 to deform. When the same vibration force is transmitted to the damping interlayer 130, the deformation of the micro elastic rubber particles inside the damping interlayer 130 changes the material parameters, cross-sectional dimensions, and structural forms encountered by the vibration wave during its transmission to the base, thereby improving the matching degree of structural impedance. This, in turn, increases the degree of reflection of the elastic wave at discontinuities, resulting in energy attenuation and ultimately achieving vibration reduction of the base.
[0044] The vibration damping base provided by this invention features a vibration damping interlayer between the upper and lower stiffeners of a conventional base. This interlayer is filled with micro-elastic rubber particles, and its hexahedral structure includes a movable sealing surface. This surface can be adjusted to the position that minimizes the vibration intensity after passing through the base, depending on the ship's navigation conditions. This allows for effective dynamic adjustment of the vibration damping interlayer according to the ship's navigation conditions, achieving rapid vibration reduction and improving the adaptability and flexibility of the vibration damping base.
[0045] Figure 3 This is one of the structural schematic diagrams of the adjustment system for the vibration damping base provided in an embodiment of the present invention. For example... Figure 3 As shown, the adjustment system of the vibration damping base includes: vibration damping base 310, control and adjustment device 320 and vibration sensor 330;
[0046] The control and adjustment device 320 is in perpendicular contact with the movable sealing surface 131 of the vibration damping base 310. This contact can be a point contact or a surface contact. The contact point can be any point on the movable sealing surface 131, and the contact surface can be any area of the movable sealing surface 131. However, for force balance, the contact point between the control and adjustment device 320 and the movable sealing surface 131 is the center of the movable sealing surface 131, or the contact surface is the central area of the movable sealing surface 131. This central area can be a symmetrical shape centered on the center of the movable sealing surface 131, such as a circle, square, or hexagon, or an asymmetrical shape centered on the center of the movable sealing surface 131. Furthermore, the area of this central area is smaller than the area of the movable sealing surface 131.
[0047] The control and adjustment device 320 is used to adjust the position of the movable sealing surface 131 so that the vibration intensity transmitted through the vibration damping base 310 to the vibration sensor 330 is minimized.
[0048] Vibration sensor 330 is disposed on the lower surface of lower stiffener 120, and the upper surface of lower stiffener 120 is in contact with the lower fixed sealing surface 134 of damping interlayer 130; the vibration sensor 330 is used to sense the vibration intensity after passing through damping base 310. Figure 3 To more clearly illustrate the position of the vibration sensor 330, in practical applications, the vibration sensor 330 is generally a patch structure, directly attached to the lower surface of the lower stiffener 120, specifically at any position on the lower surface of the lower stiffener 120. Of course, to obtain more accurate vibration intensity measurements, the vibration sensor 330 is best positioned at the center of the lower surface of the lower stiffener 120.
[0049] Figure 4This is a partially enlarged structural schematic diagram of the control and adjustment device provided in an embodiment of the present invention. (See attached diagram.) Figure 4 As shown, the control and adjustment device 320 includes: a rigid support rod 410, a drive motor 420, and an industrial computer 430;
[0050] The drive motor 420 is electrically connected to the rigid support rod 410 and is located on the same horizontal axis; the rigid support rod 410 is in perpendicular contact with the movable sealing surface 131 of the vibration damping base 310; the extension and retraction length of the rigid support rod 410 is controlled by the drive motor 420, which means that the movable sealing surface 131 of the vibration damping base 310 can be moved, thereby changing the volume of the vibration damping interlayer 130. The industrial control computer 430 is electrically connected to the drive motor 420 and the vibration sensor 330. On the one hand, the industrial control computer 430 receives the vibration intensity after passing through the vibration damping base 310 as sensed by the vibration sensor 330. On the other hand, the industrial control computer 430 controls the drive motor 420 according to the ship's navigation conditions, adjusting the adjustment range of the drive motor 420. Different adjustment ranges result in different extension and retraction lengths of the rigid support rod 410, which in turn results in different positions of the movable sealing surface 131 of the vibration damping base 310, thus changing the volume of the damping interlayer 130, until the most suitable range is adjusted to minimize the vibration intensity after passing through the vibration damping base 310 sensed by the vibration sensor 330.
[0051] It should be noted that the industrial control computer 430 in the vibration damping base adjustment system provided in this embodiment of the invention can also be an electronic device, a component in an electronic device, an integrated circuit, or a chip. The electronic device can be a mobile electronic device or a non-mobile electronic device. For example, mobile electronic devices can be mobile phones, tablets, laptops, handheld computers, in-vehicle electronic devices, wearable devices, ultra-mobile personal computers (UMPCs), netbooks, or personal digital assistants (PDAs), etc., while non-mobile electronic devices can be servers, network attached storage (NAS), personal computers (PCs), televisions (TVs), ATMs, or self-service machines, etc. This invention does not impose specific limitations.
[0052] In some embodiments, the industrial control computer is used to control the drive motor to adjust to the most suitable adjustment level according to the ship's navigation conditions, so that the vibration intensity sensed by the vibration sensor after passing through the vibration damping base is minimized, including:
[0053] When the ship's navigation conditions change, the industrial control computer controls the drive motor to adjust the extension length of the rotating screw according to the multiple adjustment gears of the drive motor, so that the movable sealing surface of the shock-absorbing interlayer moves, changing the volume of the shock-absorbing interlayer, and after the volume of the vibration interlayer changes, records the vibration intensity sensed by the vibration sensor after passing through the vibration-damping base.
[0054] The correspondence between the multiple adjustment gears of the drive motor and the vibration intensity sensed by the vibration sensor after passing through the vibration damping base is determined as the relationship between gear and vibration intensity;
[0055] Based on the relationship between the adjustment level and the vibration intensity, the adjustment level corresponding to the minimum vibration intensity is selected as the most suitable adjustment level.
[0056] Specifically, the drive motor 420 has n adjustment levels, where n is a positive integer greater than or equal to 1. When the ship's navigation conditions change, the industrial control computer 430 controls the drive motor 420 to adjust the extension length of the rigid support rod 410 by changing the adjustment level of the drive motor 420. This causes the rigid support rod 410 to push the movable sealing surface 131 of the damping interlayer 130 to move. While the other fixed sealing surfaces of the damping interlayer 130 in the damping base 310 remain stationary, the volume of the damping interlayer 130 changes. Consequently, the micro-elastic rubber particles filled within the damping interlayer 130 are compressed. This causes the external vibration force acting on the damping base 310 to be transmitted through the compressed micro-elastic rubber particles in the damping interlayer 130 of the damping base 310. As a result, the reflectivity of the vibration wave increases, meaning the attenuation of the vibration force energy increases, thus achieving a vibration reduction effect.
[0057] Each time the industrial control computer 430 changes the adjustment level of the drive motor 420, it controls the drive motor 420 to adjust the extension length of the rigid support rod 410. This causes the rigid support rod 410 to push the movable sealing surface 131 of the shock-absorbing interlayer 130 to move. Simultaneously, the vibration intensity sensed by the vibration sensor 330 is recorded. This vibration intensity is the vibration intensity of the external vibration force transmitted to the lower stiffener 120 through the shock-absorbing base 310 of the shock-absorbing interlayer 130 after a volume change. The correspondence between each adjustment level and the corresponding vibration intensity is recorded as the relationship between the adjustment level and the vibration intensity. Then, under this operating condition, the adjustment level corresponding to the minimum vibration intensity is selected as the most suitable adjustment level. In other words, through the above method, the shock-absorbing base 310 proposed in this invention is automatically adjusted according to the operating condition, so that the shock-absorbing base 310 produces the optimal vibration reduction effect for the ship's mechanical equipment under the current operating conditions, effectively ensuring a quiet working environment for the ship.
[0058] Figure 5This is a second schematic diagram of the structure of the adjustment system for the vibration damping base provided in this embodiment of the invention, as shown below. Figure 5 As shown, the drive motor 420 is fixedly connected to the bracket 440, and the bracket 440 is fixedly connected to the upper surface of the lower stiffener 120; the upper surface of the lower stiffener 120 is the surface in contact with the shock-absorbing interlayer 130.
[0059] Figure 6 This is the third schematic diagram of the structure of the adjustment system for the vibration damping base provided in this embodiment of the invention, as shown below. Figure 6 As shown, the drive motor 420 is fixedly connected to the bracket 440, and the bracket 440 is fixedly connected to the lower surface of the upper stiffening plate 110; the lower surface of the upper stiffening plate 110 is the surface in contact with the shock-absorbing interlayer 130.
[0060] Of course, the drive motor 420 may also be fixedly connected to the upper surface of the lower stiffener 120 or the lower surface of the upper stiffener 110 in other ways. This is mainly to ensure that the position of the rigid support rod 410 does not change after the drive motor 420 adjusts the gear and changes the extension length of the rigid support rod 410.
[0061] In some embodiments, such as Figure 5 As shown, the fixed sealing surface 132, parallel to the movable sealing surface 131 of the vibration damping interlayer 130, is disposed at the edges of the upper stiffening plate 110 and the lower stiffening plate 120; or as shown... Figure 6 As shown, the fixed sealing surface 132, parallel to the movable sealing surface 131 of the vibration damping interlayer 130, is positioned at a preset distance from the edges of the upper stiffening plate 110 and the lower stiffening plate 120; this preset distance is dynamically set according to application requirements. The preset distance is less than 10% of the length of the upper stiffening plate 110 and the lower stiffening plate 120.
[0062] In some embodiments, the rigid support rod 410 is a rotating screw.
[0063] In some embodiments, the rigid support rod 410 is in perpendicular contact with the center of the movable sealing surface 131 of the vibration damping base 310.
[0064] The vibration damping base adjustment system provided by the present invention sets a vibration damping interlayer between the upper and lower stiffening plates of a conventional base. The vibration damping interlayer is filled with micro elastic rubber particles, and the hexahedral structure of the vibration damping interlayer includes a movable sealing surface. It can be adjusted to the position that minimizes the vibration intensity after passing through the vibration damping base according to the ship's navigation conditions. It can effectively and dynamically adjust the vibration damping interlayer of the vibration damping base according to the ship's navigation conditions, achieve rapid vibration reduction, and improve the adaptability and flexibility of the vibration damping base.
[0065] This invention proposes a vibration damping base and its adjustment system, based on the principle of impedance mismatch, which has the following main advantages:
[0066] (1) A hexahedral vibration damping interlayer, such as a cuboid interlayer, is set between the upper and lower stiffening plates of the base. Five sides of the hexahedral vibration damping interlayer are set as static sealing surfaces, and one side is set as a dynamic sealing surface. The interior is filled with micro elastic rubber particles. The dynamic sealing surface can be translated under the action of the drive motor (with n adjustment positions) and the rotating screw, thereby adjusting the overall material parameters and cross-sectional dimensions of the cuboid interlayer and realizing the adjustment of the impedance matching characteristics of the base structure.
[0067] (2) A vibration sensor is deployed at the center of the lower stiffening plate of the base, and an industrial control computer is deployed to monitor the vibration intensity V of the ship's mechanical equipment after it passes the base in real time;
[0068] (3) Since the impedance matching characteristics of the base structure have an important impact on its vibration reduction effect, for a certain operating condition of the marine machinery equipment, the dynamic sealing surface of the rectangular interlayer of the base is translated and adjusted by the drive motor. The drive motor is set with n adjustment positions. The vibration intensity V of the center of the lower stiffener of the base is recorded by the industrial control computer at each adjustment position. The adjustment position corresponding to the minimum vibration intensity V is the optimal position suitable for the current operating condition, which can produce the best vibration reduction effect for the marine machinery equipment under this operating condition.
[0069] (4) Finally, after each change in the operating conditions of the ship's mechanical equipment, the drive motor can be adjusted to the appropriate adjustment gear according to the above steps, so that the base can produce the best vibration reduction effect on the ship's mechanical equipment under the current operating conditions, effectively ensuring the quiet working environment of the ship.
