Abstract
Description
Technical Field
[0001] This invention relates to the field of equipment vibration reduction technology, and in particular to a particle damping vibration reduction base for a vibrating screen and its optimization method. Background Technology
[0002] Particle damping devices are a novel type of vibration reduction device. They consist of a closed cavity filled with a swarm of particles. When environmental vibrations occur, the particles within the cavity rub against each other, converting mechanical vibration energy into frictional heat, thus dissipating the energy. Compared to traditional vibration reduction using damping materials, this technology offers wider frequency band coverage, broader application range, and is easier to scale down.
[0003] However, in order to improve the vibration reduction effect of the particle damping device, a large number of particles are required. This not only increases the cost of the particle damping device, but also makes the device heavier and more difficult to transport and install. Summary of the Invention
[0004] This invention provides a particle damping and vibration reduction base for a vibrating screen and its optimization method, which achieves excellent vibration absorption effect with a lighter weight and facilitates transportation and installation.
[0005] In a first aspect, the present invention provides a particle damping and vibration reduction base for a vibrating screen, which includes a vibration reduction component, a vibration isolation component and a vibration damping pad stacked sequentially from top to bottom. The vibration isolation component includes a first base plate and a second base plate spaced apart, with a vibration isolation elastic element disposed between the first base plate and the second base plate. The first base plate is connected to the top of the vibration damping pad, and the second base plate is connected to the bottom of the vibration damping component. The vibration damping component includes a housing, in which several partitions are installed, dividing the cavity of the housing into multiple receiving cavities and at least one empty cavity. Damping particles are installed in the receiving cavities. A cover is installed on the upper part of the housing, covering the top of each of the receiving cavities.
[0006] In one embodiment, the box body is provided with a plurality of cavities spaced apart from each other, and at least one receiving cavity is provided between any two adjacent cavities. In one embodiment, the cover has a plurality of notches, each notch corresponding to a cavity, and the top of the cavity is connected to the notch.
[0007] In one embodiment, the damping particles in the receiving cavity are filled with 75%-95% of the material. In one embodiment, the vibration isolation assembly includes a plurality of vibration isolation elastic elements spaced apart from each other.
[0008] In one embodiment, a plurality of vertical plates are connected to the outer side of the first base plate, and the vertical plates are connected to the outer side of the first base plate to form a mounting groove. Each of the vibration isolation elastic elements is disposed in the mounting groove, and the second base plate and the box body can move in the mounting groove in the vertical direction. In one embodiment, a limiting protrusion is provided on the outer wall of the box body, the limiting protrusion is located above the vertical plate, and the limiting protrusion extends horizontally out of the mounting groove.
[0009] In one embodiment, the bottom of the damping pad is provided with several grooves.
[0010] In one embodiment, the vibration isolation elastic element is a spring.
[0011] In one embodiment, the damping pad is made of rubber, silicone, plastic, or cork.
[0012] Secondly, the present invention also provides an optimization method for a particle-damped vibration reduction base, which is used to design the particle-damped vibration reduction base, and includes the following steps: The number of wolves in the gray wolf algorithm is set according to the set number of cavities, and H sets of cavity arrangement schemes are generated, where H≥3; The arrangement of the receiving cavities is optimized using the gray wolf algorithm: Design the box body and the partitions inside the box body based on the optimized layout scheme; The optimization of the cavity layout using the Grey Wolf algorithm includes the following sub-steps: The vibration reduction effect of the particle damping damping base corresponding to each arrangement scheme was calculated, and three optimized schemes were evaluated. Update the optimal position of the individual gray wolf; The positions of α wolf, β wolf, γ wolf, and ω wolf are defined based on historical optimization results; The hierarchical mechanism of a gray wolf pack is simulated, and the vibration reduction effect of H individual gray wolves is compared. The global optimal solution is defined as the position of wolf α, the second best solution as the position of wolf β, the next best solution as the position of wolf γ, and the rest as the position of wolf ω. Determine the location for the gray wolves to hunt them down; Simulate the behavior of gray wolf packs hunting prey, and determine the next hunting position of individual gray wolves based on the positions of α wolves, β wolves, γ wolves and the historical best position of individual gray wolves; The optimal solution is optimized using the Grey Wolf algorithm until the maximum number of iterations is reached; The arrangement of the receiving cavity is determined based on the optimal solution in the last optimization scheme.
[0013] In one implementation, updating the optimal position of the individual gray wolf includes the following steps:
[0014]

[0017] In the formula, This indicates the current location of the prey obtained by the gray wolf after the t-th iteration; Let represent the current position of the gray wolf after the t-th iteration, d represent the step size parameter, ci represent a random vector used to increase the randomness of the algorithm, a is in the interval [0, 2] and decreases as the number of iterations increases, r1 and r2 are random numbers in the interval [0, 1], and |·| represents the modulus (Euclidean distance) of the two-dimensional vector.

[0019] in, (j=α, β, γ) represents the current position of gray wolf individuals α, β, and γ after the t-th iteration.
[0020] Compared with existing technologies, the advantages of this invention lie in its three-stage vibration damping structure, comprising a vibration damping component, a vibration isolation component, and a vibration buffer pad. This structure effectively isolates and dissipates vibrations, reducing the transmission of vibrations. Specifically, the vibration isolation component can be connected to the vibrating equipment, and the vibration buffer pad can be connected to the ground or floor slab. The vibrations from the vibrating equipment are first partially converted into frictional heat by the damping particles within the vibration isolation component. Any remaining vibration energy is also isolated by the vibration isolation component and the vibration buffer pad, significantly reducing the impact of the vibrating equipment on the ground or floor slab. Furthermore, compared to simple particle damping devices, fewer damping particles can achieve the same or even stronger vibration isolation effect, thereby reducing the weight of the vibration damping device and simplifying installation and transportation.

Detailed Implementation
[0024] The invention will now be further described with reference to the accompanying drawings.
[0025] See Figures 1-4 As shown, the present invention provides a particle damping and vibration reduction base for a vibrating screen, which includes a vibration reduction component 100, a vibration isolation component 200 and a vibration damping pad 600 stacked sequentially from top to bottom; The vibration isolation assembly 200 includes a first base plate 210 and a second base plate 220 spaced apart. A vibration isolation elastic element 230 is provided between the first base plate 210 and the second base plate 220. The first base plate 210 is connected to the top of the damping pad 600, and the second base plate 220 is connected to the bottom of the vibration damping assembly 100. The vibration damping assembly 100 includes a housing 110, and a plurality of partitions 120 are installed inside the housing 110. The partitions 120 divide the cavity of the housing 110 into a plurality of receiving cavities 131 and at least one empty cavity 132. A cover 140 is installed on the upper part of the housing 110, and the cover 140 covers the top of each receiving cavity 131.
[0026] When in use, the particle damping base of the vibrating screen can be placed where vibration reduction is needed, such as between the floor and the vibrating screen. When the vibrating screen vibrates, it will drive the particle damping base connected to the vibrating screen to move together, transferring part of the vibration energy of the vibrating screen to the particle damping base, causing the damping particles in the receiving cavity 131 to shake. Through the mutual friction between the damping particles, the vibration energy is converted into heat, absorbing the vibration energy more quickly and preventing the floor from vibrating significantly due to the vibration of the vibrating screen.
[0027] Vibrational energy that is not completely absorbed by the upper vibration damping component 100 will be transmitted to the lower vibration damping component 100 and the damping pad 600. Through the vibration isolation and absorption of the vibration isolation component 200 and the damping pad 600, the vibrational energy can be further consumed, thereby achieving a better vibration isolation effect, isolating the lateral transmission of vibration, and further reducing the impact of vibration on other equipment or buildings.
[0028] The technical solution of this application can initially absorb the vibration energy of the vibrating screen with a small number of damping particles. The remaining energy can then be absorbed by the vibration isolation component 200 and the damping pad 600. While achieving the same vibration reduction effect, the number of damping particles is greatly reduced, the weight of the device is reduced, and the transportation and installation of the particle damping vibration reduction base of the vibrating screen are facilitated.
[0029] Furthermore, in this application, the cavity of the box 110 is divided by a partition 120 to form a smaller receiving cavity 131 and an empty cavity 132. Compared to placing the damping particles directly in the box 110 without the partition 120, the partition 120 restricts the movement range of each damping particle, thereby preventing excessive aggregation of damping particles and affecting the stable operation of the device. That is, by setting the partition 120 to restrict the movement range of the damping particles in this application, the damping particles can always move near the filling area, so that the distribution of damping particles during operation is the same as the initial state, avoiding the reduction of vibration damping effect caused by changes in the distribution area of damping particles. Moreover, because the empty cavity 132 is not filled with damping particles, the number of damping particles can be further reduced while maintaining the same force-bearing area, thus reducing the weight of the device.
[0030] In this application, the selection of damping particles follows the properties: the friction factor is 0.01 - 0.99, the surface restitution coefficient is 0.01 - 1, the particle density is 0.1 - 30 g / m3, the elastic modulus is 1 - 300 GPa, and the Poisson's ratio is 0.1 - 1. The damping particles are one or more of spheres with a diameter of 0.001 - 30 mm, ellipsoids with major and minor axis lengths between 0.01 - 30 mm, and regular or irregular polyhedrons with side lengths of 0.001 - 30 mm. To enable the damping particles to have greater freedom of movement, increase the collision probability between particles, thereby increasing damping and having better vibration resistance, preferably, the damping particles are spheres with a diameter of 0.1 - 5 mm.
[0031] The material of the damping particles can be metal, non-metal or polymer composite material. Preferably, the damping particles are metal, and more preferably, the damping particles are alloy materials, such as copper-zinc-aluminum series, iron-chromium-molybdenum series and manganese-copper series alloys, which have a wide temperature and frequency application range.
[0032] It can be understood that the particle damping vibration reduction base of the vibrating screen provided in this embodiment can not only be used to achieve the vibration absorption of the vibrating screen, but also the particle damping vibration reduction base of the vibrating screen can be arranged in the vehicle to absorb the vibration of the vehicle.
[0033] See Figures 1-4 As shown, in some implementation manners, the accommodation cavities 131 on the box body 110 are arranged at intervals along the length direction of the box body 110, so that the notches 141 of the cover body 140 are also arranged at intervals along the length direction of the box body 110, forming a "mesh" shaped cover plate.
[0034] See Figures 1-4 As shown, in some implementation manners, the cover body 140 is provided with a plurality of notches 141, and the notches 141 are arranged in one-to-one correspondence with the cavities 132, and the top of the cavity 132 is connected to the notch 141. That is to say, when the cover body 140 is covered on the box body 110, the part of the accommodation cavity 131 filled with damping particles will be covered by the cover body 140 to prevent the damping particles in the accommodation cavity 131 from flying out, while the top of the cavity 132 not filled with damping particles corresponds to the cavity 132. On the one hand, setting the notch 141 can reduce the solid material of the cover body 140 and reduce the material cost of the cover body 140. At the same time, it can also directly connect the cavity 132 with the top space of the particle damping vibration reduction base of the vibrating screen, so that the cavity 132 forms a containing structure to contain some parts or sundries.
[0035] Understandably, in some implementations, cavity 132 can be used to receive cryogenic coolant or cold air, so that the damping particles in the receiving cavity 131 can be cooled more quickly during cooling. That is, the damping particles in the receiving cavity 131 can be cooled by circulating cryogenic coolant or cold air into cavity 132. Because cavity 132 is surrounded by multiple receiving cavities 131, when the temperature rises in the receiving cavity 131 due to friction of the damping particles, the coolant in cavity 132 can quickly carry away the heat, so that the temperature of the damping particles in the receiving cavity 131 can be maintained at a low level, avoiding melting or deformation of the damping particles due to excessive temperature, and reducing the subsequent frictional heat generation efficiency.
[0036] In some implementations, the filling rate of damping particles in the cavity 131 is 75%-95%. This allows the damping particles in the cavity 131 to fit together relatively tightly while leaving some space for movement. This allows the damping particles in the cavity 131 to move during vibration, thereby achieving mutual friction between the damping particles and converting the vibration energy into heat generated by the friction of the damping particles, thus absorbing the vibration energy.
[0037] See Figures 1-4 As shown, in some implementations, the vibration isolation assembly 200 includes a plurality of vibration isolation elastic elements 230, which are spaced apart from each other. Vibration isolation between the first base plate 210 and the second base plate 220 is achieved through the multiple spaced vibration isolation elastic elements 230. Compared with vibration isolation using a single vibration isolation elastic element 230, this not only provides better vibration isolation but also better support for the second base plate 220, improving the stability of the vibration damping assembly 100. The vibration isolation elastic element 230 is a vibration isolation spring, and the vibration isolation assembly 200 includes ten vibration isolation elastic elements 230, arranged in two columns, each column having five vibration isolation elastic elements 230. The five elastic elements in each column are spaced apart along the length of the housing 110 of the vibration damping assembly 100, achieving stable support and vibration isolation for the vibration damping assembly 100.
[0038] See Figures 1-4 As shown, in some implementations, a plurality of vertical plates 240 are connected to the outer side of the first base plate 210. The vertical plates 240 and the outer side of the first base plate 210 form a mounting groove. Each of the vibration-damping elastic elements 230 is disposed within the mounting groove. The second base plate 220 and the housing 110 can move vertically within the mounting groove. By providing the mounting groove formed by the vertical plates 240 and the first base plate 210, the probability of foreign objects contacting the vibration-damping elastic elements 230 can be reduced, thus extending the service life of the vibration-damping elastic elements 230.
[0039] See Figures 1-4As shown, in some implementations, a limiting protrusion 111 is provided on the outer wall of the box 110. The limiting protrusion 111 is located above the vertical plate 240 and extends horizontally out of the mounting groove.
[0040] By providing limiting protrusions 111 on the outer wall of the box body 110, the height of the box body 110 can be prevented from dropping too low, thus limiting the height of the box body 110. In the illustration, three limiting protrusions 111 are provided on one side of the box body 110, and three limiting protrusions 111 are provided on the other side of the box body 110. These six limiting protrusions 111 effectively limit the height of the box body 110, improving its stability.
[0041] See Figures 1-4 As shown, in some implementations, the bottom of the damping pad 600 is provided with several grooves 610. By providing grooves 610, the amount of compression deformation of the damping pad 600 can be increased, so that the damping pad 600 can achieve better vibration energy absorption.
[0042] Among them, the vibration isolation elastic element 230 can be a spring, which is not only easy to obtain, but also has good vibration isolation performance.
[0043] In some implementations, the second base plate 220 is the lower base plate of the box body 110. The box body 110, the first base plate 210, and the vertical plate 240 are all made of metallic materials, such as iron alloys, copper alloys, aluminum alloys, titanium alloys, or tungsten alloys. They possess good rigidity and toughness, can withstand dynamic loads well, and have strong resistance to deformation. They can be used to construct large-span, super-high, and super-heavy buildings. Their homogeneity and isotropy are good, best conforming to the basic assumptions of general engineering mechanics.
[0044] In some implementations, the vibration damping pad 600 is made of rubber, silicone, plastic or cork, all of which have good vibration isolation performance. When in use, the vibration damping pad 600 is connected to the first base plate 210 by bolts, expansion joints or adhesive bonding.
[0045] See Figure 5 as well as Figure 6 As shown, in a second aspect, the present invention also provides an optimization method for a particle-damped vibration reduction base, which includes the following steps: S1: Set the number of wolves in the gray wolf algorithm according to the set number of accommodating cavities 131, and generate H sets of arrangement schemes for accommodating cavities 131, where H≥3; S2: Optimize the layout of the receiving cavity 131 using the gray wolf algorithm: S1: Design the box body 110 and the partition 120 inside the box body 110 according to the optimized layout scheme; The optimization of the arrangement scheme of the receiving cavity 131 using the gray wolf algorithm includes the following sub-steps: S21: Calculate the vibration reduction effect of the particle damping base corresponding to each arrangement scheme, and evaluate the three optimized schemes. S22: Update the optimal position of the individual gray wolf; S23: Define the positions of α wolf, β wolf, γ wolf, and ω wolf based on historical optimization results; The hierarchical mechanism of a gray wolf pack is simulated, and the vibration reduction effect of H individual gray wolves is compared. The global optimal solution is defined as the position of wolf α, the second best solution as the position of wolf β, the next best solution as the position of wolf γ, and the rest as the position of wolf ω. S24: Determine the location for the gray wolves to hunt; Simulate the behavior of gray wolf packs hunting prey, and determine the next hunting position of individual gray wolves based on the positions of α wolves, β wolves, γ wolves and the historical best position of individual gray wolves; S25: Optimize the preferred solution using the Grey Wolf algorithm until the maximum number of iterations is reached; S26: Determine the arrangement of the receiving cavity 131 based on the optimal scheme in the last optimization scheme.
[0046] In each arrangement scheme of the receiving cavity 131, there are coordinate parameters of each receiving cavity 131. For example, when N receiving cavities 131 need to be arranged, and the coordinates of each receiving cavity 131 include two parameters, the horizontal and vertical coordinates, a set of arrangement schemes has 2*N parameters. That is, α wolf, β wolf, γ wolf and ω wolf actually correspond to an array with a data length of 2*N.
[0047] The Grey Wolf algorithm can find the optimal distribution scheme more quickly, thereby obtaining the optimal position coordinates of each receiving cavity 131, which actually corresponds to the setting position of each partition 120. The position of the receiving cavity 131 designed with the optimal distribution scheme can obtain a higher vibration reduction score and bring better vibration reduction effect.
[0048] In step S21, when calculating the vibration reduction effect of the particle damping base corresponding to each arrangement scheme, the corresponding arrangement scheme can be input into the vibration simulation software, and the simulation data of the vibration simulation software can be used as the vibration reduction effect score. The scheme with the best score is the α wolf scheme, the scheme with the second best score is the β wolf scheme, and the scheme with the third best score is the β wolf scheme. The score data of each time will be recorded so as to update the three optimal solutions of the gray wolf scheme by combining the vibration evaluation data of the current iteration scheme and the historical schemes. In some implementations, updating the optimal position of the individual gray wolf includes the following steps:

[0052] In the formula, This indicates the current location of the prey obtained by the gray wolf after the t-th iteration; Let represent the current position of the gray wolf after the t-th iteration, d represent the step size parameter, ci represent a random vector used to increase the randomness of the algorithm, a is in the interval [0, 2] and decreases as the number of iterations increases, r1 and r2 are random numbers in the interval [0, 1], and |·| represents the modulus (Euclidean distance) of the two-dimensional vector.
[0053] In some implementations, the encirclement model used to determine the gray wolf encirclement location is as follows:
[0054] in, (j=α, β, γ) represents the current position of gray wolf individuals α, β, and γ after the t-th iteration.
[0055] In this application, the optimized gray wolf algorithm was combined to obtain the following results: Figure 2 The arrangement of the accommodating cavities 131 shown is such that the accommodating cavities 131 surround each other to form four cavities 132, and each cavity 132 is of equal size and is spaced equally along a straight line.
[0056] Understandably, if the stress conditions are different, or the shape of the box 110 is different, other optimization schemes can be obtained to achieve the corresponding optimized arrangement and improve the vibration reduction effect.
[0057] Although the invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict. The invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
