Abstract
Description
Technical Field
[0001] This disclosure relates to the field of vibration control technology, and in particular to an automatic vibration damping system for a flexible rotating shaft with one end constrained, and its control method, device, storage medium and electronic equipment. Background Technology
[0002] According to the basic theory of rotor dynamics, a general synchronous precession problem will exist in the actual operation of a dynamically unbalanced impeller and its flexible shaft, such as... Figure 1 As shown, with the widespread use of modern high-speed fans, the speed of more and more fans is approaching or completely exceeding the first critical speed of the rotor. The synchronous precession of the impeller rotor running near the critical speed will more easily excite its corresponding modes, thus leading to greater vibration problems.
[0003] Before mass production and installation, wind turbine impellers undergo dynamic balancing to reduce vibration caused by dynamic imbalance during assembly and operation. However, this does not guarantee complete dynamic balance. Even for low-speed impeller shaft systems, due to the specific nature of their working environment, such as oil fume environments, the accumulation of oil stains or dust over time can deteriorate the rotor's original dynamic balance, leading to increased impeller rotor vibration.

When the adjusting disc is attached to the rotating shaft electromagnet, the drive motor drives the axial adjusting device, causing it to rotate the balancing device axially. By adjusting the center of gravity of the balancing device during rotation, the optimal position is found, further offsetting the eccentric force during the rotation of the flexible shaft and reducing vibration. Under the combined adjustment of the lateral and axial adjusting devices, the optimal position for the balancing device to offset the eccentric force is determined, achieving vibration minimization control, reducing noise generated by vibration in the system containing the flexible shaft, and increasing system stability.

[0108] Figure 2 and Figure 3 This diagram illustrates the structure of an automatic vibration damping system for a flexible rotating shaft with one end constrained according to an embodiment of the present disclosure. Figure 2 and Figure 3 As shown, the above system includes:
[0109] 1. Drive motor, 2. Rotary shaft electromagnet, 3. Balancing device, 4. Adjusting disc, 5. Axial adjustment device, and 6. Lateral adjustment device;
[0110] Drive motor 1 is used to drive shaft electromagnet 2. Lateral adjustment device 6 is fixedly connected to shaft electromagnet 2. Adjustment disk 4 is fixedly connected to axial adjustment device 5. Balancing device 3 is slidably connected to axial adjustment device 5. Balancing device 3 and lateral adjustment device 6 are partially connected.
[0111] When the adjusting plate 4 is not attracted to the rotating shaft electromagnet 2, the lateral adjusting device 6 is driven by the drive motor 1 so that the lateral adjusting device 6 drives the balancing device 3 to move laterally.
[0112] With the adjusting plate 4 attracted to the rotating shaft electromagnet 2, the axial adjusting device 5 is driven by the drive motor 1, so that the axial adjusting device 5 drives the balancing device 3 to rotate axially.
[0113] The rotating shaft electromagnet 2 can rotate under the drive of the drive motor 1, and it becomes magnetic when energized, losing its magnetism when de-energized. The balancing device 3 is the object to be adjusted by the lateral adjustment device 6 and the axial adjustment device 5; it affects the eccentric force during the rotation of the flexible shaft. The adjusting disc 4 can be attracted by the energized electromagnet. The axial adjustment device 5 can adjust the balancing device 3 laterally, and it can also adjust the balancing device 3 by rotation.
[0114] In some embodiments, the drive motor 1 and the rotating shaft electromagnet 2 are drivenly connected. When the drive motor 1 is turned on and rotates, it drives the rotating shaft electromagnet 2 to rotate. The adjusting disk 4 is fixedly connected to the axial adjustment device 5. When the adjusting disk 4 and the rotating shaft electromagnet 2 are not connected, the rotating shaft electromagnet 2 cannot drive the adjusting disk 4 to rotate when it rotates, and therefore cannot drive the axial adjustment device 5 to rotate.
[0115] When the rotating shaft electromagnet 2 is de-energized, it does not have an attraction function. When the adjusting disk 4 and the rotating shaft electromagnet 2 are disconnected, and the drive motor 1 starts rotating, it drives the rotating shaft electromagnet 2 to rotate. The rotating shaft electromagnet 2 then drives the lateral adjustment device 6 to rotate, thereby causing the balancing device 3 to move laterally. During the rotation of the flexible shaft, the lateral adjustment device 6 moves the balancing device 3 laterally to find the optimal lateral position, minimizing the vibration of the flexible shaft rotation.
[0116] like Figure 4 As shown, when the rotating shaft electromagnet 2 is energized, it has an adsorption function and is adsorbed to the adjusting plate 4. When the drive motor 1 starts rotating, it drives the rotating shaft electromagnet 2 to rotate. The rotating shaft electromagnet 2 drives the axial adjusting device 5 and the lateral adjusting device 6 to rotate together, thereby causing the balancing device 3 to rotate accordingly. During the rotation of the flexible shaft, the lateral adjusting device 6 rotates the balancing device 3 to find the optimal position during rotation, minimizing the vibration of the flexible shaft.
[0117] In some embodiments, the adjusting disk 4 may be disc-shaped, the rotating shaft electromagnet 2 may be cylindrical, and the radius of the adjusting disk 4 may be the same as the radius of the rotating shaft electromagnet 2.
[0118] In some embodiments, the drive motor 1 is fixedly connected to the tightening nut, and the tightening nut is fixedly connected to the unconstrained end of a constrained flexible rotating shaft.
[0119] In some embodiments, the automatic vibration damping system 100 can be applied to a wind turbine impeller shaft system. (See also...) Figure 5The automatic vibration damping system 100 is installed in the fan inlet channel and the tightening nut of the impeller as one unit. The tightening nut fixes the automatic vibration damping system 100 to the front end of the impeller.
[0120] In some embodiments, the automatic vibration damping system 100 further includes a vibration detection device mounted on the mounting plate of the main drive, which is a drive for driving the flexible shaft, and the vibration detection device is used to monitor the vibration data of the system in which the flexible shaft is located.
[0121] In some embodiments, the vibration monitoring device may be a vibration sensor.
[0122] The above technical solution cleverly adjusts the position of the balancing device 3 in the system through the structure of the automatic vibration damping system 100, thereby minimizing the vibration during the rotation of the flexible shaft. The structure is simple and cost-effective.
[0123] Please see Figure 4 In some embodiments, the axial adjustment device 5 includes a transmission box, which is fixedly connected to the adjustment disc 4. The transmission box is used to drive the balancing device 3 to rotate.
[0124] Furthermore, part of the lateral adjustment device 6 is located inside the transmission box. The transmission box has through holes on both sides adjacent to the connection with the adjustment plate 4, allowing the balancing device 3 to pass through from inside the transmission box. Parts of the balancing device 3 and the lateral adjustment device 6 are connected inside the transmission box by gears.
[0125] The above technical solution uses a balancing device 3 inserted into a transmission box, so that when the transmission box rotates, it can drive the balancing device 3 to rotate, thereby adjusting the position of the balancing device 3 in the direction of rotation.
[0126] In some embodiments, the lateral adjustment device 6 includes a fixing module 61, which includes a curved body and a flat body. One side of the curved body and the flat body are fixedly connected. The curved body is fixedly connected to the drive motor 1. The adjustment disk 4 is disposed between the flat body and the rotating shaft electromagnet 2. The adjustment disk 4 is attracted to the flat body or the adjustment disk 4 is attracted to the rotating shaft electromagnet 2.
[0127] In some embodiments, the fixing module 61 is an L-shaped structure composed of a curved surface and a flat surface. The fixing module 61 is made of an electromagnet, which becomes magnetic when energized and loses its magnetism when de-energized. The curved surface is suspended on the rotating shaft electromagnet 2 and fixedly connected to the housing of the drive motor 1. The flat surface is on the other side of the rotating shaft electromagnet 2. An adjusting disk 4 is disposed between the flat surface and the rotating shaft electromagnet 2, and the adjusting disk 4 can be tilted to either side of the flat surface and the rotating shaft electromagnet 2.
[0128] Furthermore, when the fixed module 61 is energized and the rotating shaft electromagnet 2 is not energized, the adjusting disk 4 and the fixed module 61 are magnetically connected, such as... Figure 6 As shown, the rotating shaft electromagnet 2 is disconnected from the adjusting plate 4. Therefore, when the drive motor 1 drives the rotating shaft electromagnet 2 to rotate, the adjusting plate 4 is fixed by the fixing module 61 and does not rotate. Consequently, the axial connecting device connected to the adjusting plate 4 will not rotate.
[0129] When the fixed module 61 is de-energized, the adjustment disk 4 and the fixed module 61 are disconnected.
[0130] The above technical solution, through the coordinated action of the fixed module 61 and the rotating shaft electromagnet 2, allows switching between lateral adjustment mode and axial adjustment mode, saving costs and making adjustment convenient.
[0131] In some embodiments, the lateral adjustment device 6 further includes a drive shaft 62, which is fixedly connected to a rotating shaft electromagnet 2. The rotating shaft electromagnet 2 is also used to drive the drive shaft 62 to rotate.
[0132] Furthermore, the drive shaft 62 is housed inside the transmission box and is not in contact with the transmission box. The drive shaft 62 is connected to the rotating shaft electromagnet 2. When the rotating shaft electromagnet 2 rotates, it drives the drive shaft 62 to rotate. When the transmission box does not rotate, the balancing device 3 moves laterally.
[0133] The above technical solution allows the drive shaft 62 to rotate, which in turn drives the balancing device 3 to move laterally. This achieves lateral adjustment of the center of gravity of the balancing device 3 in a simple way, thereby reducing the vibration of the flexible shaft rotation, facilitating adjustment, and saving costs.
[0134] In some embodiments, the balancing device 3 includes a balancing arm 31, a first mass body 32 and a second mass body 33, the first mass body 32 and the second mass body 33 having the same mass, and the first mass body 32 and the second mass body 33 being respectively disposed at both ends of the balancing arm 31.
[0135] Furthermore, the balance arm 31 passes through the transmission box and is connected to the transmission shaft 62 inside the transmission box. A first mass body 32 and a second mass body 33 are respectively provided at both ends of the balance arm 31, such as... Figure 3 As shown; the initial state of the balancing device 3 is that the drive shaft 62 is at the center of the balancing arm 31, and the first mass body 32 and the second mass body 33 are symmetrical about the drive shaft 62.
[0136] In some embodiments, the weights of the first mass body 32 and the second mass body 33 are set based on actual needs. The heights of the first mass body 32 and the second mass body 33 are the same, and the heights of the first mass body 32 and the second mass body 33 are greater than the height of the gear shaft. The gear shaft can be a cylinder, and its height is the diameter of the circular side surface of the cylinder. By designing the heights of the first mass body 32 and the second mass body 33, the balancing device 3 achieves static balance in the vertical direction, which is perpendicular to the balancing arm 31.
[0137] It should be noted that the horizontal direction mentioned throughout the text refers to the direction of the longest side of the balance arm 31, that is, the straight line formed by the balance arm 31 connecting the first mass body 32 and the second mass body 33. The axial direction mentioned throughout the text refers to the direction of rotation of the rotating electromagnet 2.
[0138] In some embodiments, the balance arm 31 is in the form of a rectangular sheet. The first mass body 32 and the second mass body 33 can be cuboids or cubes, and there is no limitation on this.
[0139] The above technical solution uses the balancing device 3 to counteract the eccentric force during the rotation of the flexible shaft, thus reducing vibration simply and effectively.
[0140] In some embodiments, a gear belt is provided on the balance arm 31, and a gear corresponding to the gear belt is provided on the drive shaft 62. The drive shaft 62 moves or is fixed on the gear belt of the balance arm 31 through the gear.
[0141] Furthermore, gear belts are installed at predetermined distances from the center of the balance arm 31 to both sides of the first mass body 32 and the second mass body 33. Gears corresponding to the gear belts are wrapped around the outside of the drive shaft 62. When the drive shaft 62 rotates while the transmission box remains stationary, the drive shaft 62 moves along the balance arm 31, causing the balancing device 3 to move left and right. When the transmission box rotates, causing the balancing device 3 to rotate, the friction between the gears in the transmission box and the gear belts of the balance arm 31 can fix the balancing device 3 in place, preventing it from sliding along the balance arm 31 during rotation.
[0142] According to the second aspect of this disclosure, please refer to Figure 7 This paper provides a control method for an automatic vibration damping system of a flexible rotating shaft with one-end constraint. Based on the system described above, the method includes:
[0143] S101. Obtain the first vibration data of the flexible rotating shaft;
[0144] S102, Control the rotating shaft electromagnet to disconnect from the adjusting plate, and control the fixed module and the adjusting plate to be attracted and connected;
[0145] S103. Control the drive motor to drive the rotating shaft electromagnet to rotate by a first preset angle, so as to drive the lateral adjustment device, and make the lateral adjustment device drive the balancing device to move laterally.
[0146] S104. After the balancing device has moved laterally, acquire the second vibration data of the flexible rotating shaft;
[0147] S1041. If the first vibration data is greater than the second vibration data, the balancing device is adjusted laterally based on the second vibration data using the lateral adjustment device.
[0148] or,
[0149] S1042. If the first vibration data is greater than the second vibration data, the balancing device is axially adjusted based on the second vibration data using the axial adjustment device.
[0150] When the flexible shaft rotates, an automatic vibration damping system is used to adjust the vibration generated by the rotation of the flexible shaft.
[0151] The first vibration data A0 of the flexible rotating shaft is obtained based on the vibration detection device; the rotating shaft electromagnet is de-energized, and at the same time, the fixing module is energized, so that the rotating shaft electromagnet is disconnected from the adjusting plate, and the fixing module and the adjusting plate are magnetically connected. The drive motor is turned on, and the drive motor drives the rotating shaft electromagnet to rotate a first preset angle. This causes the lateral adjustment device to drive the balancing device to produce a certain displacement in the direction of the balance arm, and then the drive motor is turned off. After the balancing device completes its lateral movement, the second vibration data A1 of the flexible rotating shaft is acquired; it is then determined whether the first vibration data A0 is greater than the second vibration data A1. If the first vibration data A0 is greater than the second vibration data A1, the lateral adjustment device is used to adjust the balancing device laterally based on the second vibration data to determine the optimal lateral position of the balancing device, so that the vibration data detected by the vibration detection device is relatively minimized. Alternatively, the axial adjustment device is used to adjust the balancing device rotationally based on the second vibration data to determine the optimal position of the balancing device during rotation, so that the vibration data detected by the vibration detection device is relatively minimized.
[0152] In some embodiments, the balancing device is laterally adjusted using a lateral adjustment device based on the second vibration data. After the lateral position of the balancing device is fixed, the first target vibration data is acquired. The second vibration data A1 is then updated based on the first target vibration data. Finally, the balancing device is axially adjusted using an axial adjustment device based on the second vibration data A1. The optimal lateral position is first adjusted using the lateral adjustment device, and then the optimal axial position is adjusted using the axial adjustment device to achieve the final optimal position determination, thereby minimizing vibration.
[0153] In some embodiments, the balancing device is rotated using an axial adjustment device based on the second vibration data. After the axial position of the balancing device is fixed, second target vibration data is acquired. The second vibration data A1 is updated based on the second target vibration data, and then the balancing device is laterally adjusted using a lateral adjustment device based on the second vibration data A1. The axial optimal position is first adjusted using the axial adjustment device, and then the lateral optimal position is adjusted using the lateral adjustment device to achieve the final optimal position determination, thereby minimizing vibration.
[0154] In some embodiments, when acquiring the first vibration data of the flexible rotating shaft, the balancing device is in an initial state, where the drive shaft 62 is at the center of the balancing arm, and the first mass body and the second mass body are symmetrical about the drive shaft 62.
[0155] In some embodiments, the above method can be applied to a wind turbine impeller shaft system equipped with an automatic vibration damping system. The wind turbine impeller shaft system includes a flexible shaft constrained at one end.
[0156] The above technical solution, when adjusting the vibration of the system containing the flexible rotating shaft, first obtains the first vibration data before adjustment and the second vibration data after fine adjustment. If the first vibration data before adjustment is greater than the second vibration data after fine adjustment, it indicates that the adjustment method is effective. Then, axial or lateral adjustment is continued to minimize the vibration data, thereby minimizing the vibration of the system containing the flexible rotating shaft, reducing noise, and improving the stability of the system.
[0157] Please see Figure 8 In some embodiments, the method further includes:
[0158] S201. When the first vibration data is less than or equal to the second vibration data, control the fixed module and the adjustment plate to disconnect, and control the rotating shaft electromagnet to be attracted and connected to the adjustment plate.
[0159] S202. Control the drive motor to drive the rotating shaft electromagnet to rotate by a second preset angle based on the first direction, so as to drive the axial adjustment device, so that the axial adjustment device drives the balancing device to rotate along the first direction.
[0160] S2021. After the balancing device has rotated, the balancing device is laterally adjusted based on the second vibration data using the lateral adjustment device.
[0161] or,
[0162] S2022. After the balancing device has rotated, the rotation of the balancing device is adjusted by the axial adjustment device based on the second vibration data.
[0163] Specifically, if the first vibration data A0 is less than or equal to the second vibration data A1, it means that continuing in this adjustment direction will not reduce the vibration. Therefore, the fixed module is de-energized, causing the fixed module and the adjustment disk to disconnect. The rotating shaft electromagnet is energized, causing the rotating shaft electromagnet and the adjustment disk to be attracted and connected. Then, the drive motor is turned on, causing the drive motor to drive the rotating shaft electromagnet to rotate a second preset angle based on the first direction. The rotating shaft electromagnet further drives the adjustment disk and the axial adjustment device to rotate, and the axial adjustment device drives the balancing device to rotate. After the rotation is completed, the drive motor is turned off.
[0164] After the balancing device has rotated, it is adjusted laterally using a lateral adjustment device based on the second vibration data to determine the optimal lateral position of the balancing device, minimizing the vibration data detected by the vibration detection device. Alternatively, it can be adjusted by rotating the balancing device using an axial adjustment device based on the second vibration data to determine the optimal position of the balancing device during rotation, minimizing the vibration data detected by the vibration detection device. The order of these adjustment methods can be varied.
[0165] In some embodiments, the first direction is clockwise and the second preset angle is 180 degrees.
[0166] In the above technical solution, when adjusting the vibration of the system containing the flexible rotating shaft, the first vibration data before adjustment and the second vibration data after fine adjustment are first obtained. If the first vibration data before adjustment is less than or equal to the second vibration data after fine adjustment, it indicates that the adjustment method is ineffective. The position of the balancing device is changed, and vibration adjustment is continued to ensure the effectiveness of vibration adjustment.
[0167] Please see Figure 9 In some embodiments, the balancing device is axially adjusted based on the second vibration data using an axial adjustment device, including:
[0168] S421, Control the fixed module and the adjustment plate to disconnect, and control the rotating shaft electromagnet and the adjustment plate to be attracted and connected;
[0169] S422. Control the drive motor to drive the rotating shaft electromagnet to rotate a third preset angle based on the first direction, so as to drive the axial adjustment device, so that the axial adjustment device drives the balancing device to rotate along the first direction.
[0170] S423. After the balancing device has rotated, acquire the third vibration data of the flexible shaft;
[0171] S424. If the second vibration data is greater than the third vibration data, control the drive motor to drive the rotating shaft electromagnet to continue rotating a third preset angle based on the first direction.
[0172] S425. After the rotating shaft electromagnet has finished rotating, acquire the fourth vibration data of the flexible rotating shaft;
[0173] S426. When the third vibration data is less than or equal to the fourth vibration data, control the drive motor to drive the rotating shaft electromagnet to rotate by a third preset angle based on the second direction, and determine the final state of the axial adjustment of the balancing device, wherein the first direction and the second direction are opposite directions.
[0174] Specifically, the fixed module is de-energized, disconnecting it from the adjustment plate; the rotating shaft electromagnet is energized, attracting it to the adjustment plate; and the drive motor is activated, causing it to rotate the rotating shaft electromagnet in the first direction by a third preset angle. The rotating shaft electromagnet drives the adjusting plate and the axial adjusting device fixedly connected to the adjusting plate to rotate together, thereby causing the balancing device to rotate accordingly, and the drive motor is turned off. After the balancing device has rotated, based on the third vibration data A11 obtained by the vibration detection device, the magnitudes of the second and third vibration data are compared. If the second vibration data is greater than the third vibration data A11, the drive motor is turned on to continue driving the rotating shaft electromagnet to rotate the third preset angle in the first direction. Turn off the drive motor and acquire the fourth vibration data A12 of the flexible shaft; determine the magnitudes of the third vibration data A11 and the fourth vibration data A12. If the third vibration data A11 is less than or equal to the fourth vibration data A12, it indicates that the vibration data in the previous adjustment step is less than the adjusted vibration data. Turn on the drive motor so that it drives the shaft electromagnet to rotate a third preset angle based on the second direction. This allows the balancing device to return to the position of the previous adjustment step, ultimately determining the final position of the balancing device's rotation under the adjustment of the axial adjustment device.
[0175] In some embodiments, the second direction is counterclockwise.
[0176] The above technical solution utilizes an axial adjustment device and a rotational balancing device to adjust the vibration, while detecting the magnitude of the vibration data during the adjustment process, thereby optimizing the vibration data and making the adjustment method simple and effective.
[0177] Please see Figure 10 In some embodiments, the method further includes:
[0178] S4261. When the third vibration data is greater than the fourth vibration data, control the drive motor to drive the rotating shaft electromagnet to continue rotating a third preset angle based on the first direction.
[0179] S4262. After the rotating shaft electromagnet has finished rotating, acquire the fifth vibration data of the flexible rotating shaft;
[0180] S4263. Update the third vibration data based on the fourth vibration data, and update the fourth vibration data based on the fifth vibration data.
[0181] Specifically, if the third vibration data A11 is greater than the fourth vibration data A12, it indicates that the adjusted vibration data has decreased. The drive motor is then activated, continuing to drive the rotating shaft electromagnet to rotate a third preset angle based on the first direction. Turn off the drive motor and continue to acquire the fifth vibration data of the flexible rotating shaft. Determine the fourth vibration data as the third vibration data and the fifth vibration data as the fourth vibration data. Continue to judge the magnitude of the third vibration data and the fourth vibration data. Repeat the process of adjusting the rotation of the balancing device based on the first direction when the third vibration data is greater than the fourth vibration data, or adjusting the rotation of the balancing device based on the second direction when the third vibration data is less than or equal to the fourth vibration data, until the final position of the rotation of the balancing device under the adjustment of the axial adjustment device is finally determined.
[0182] If the above technical solution is effective in adjusting the vibration along the same direction, it will continue to be adjusted until the final position of the rotation of the balancing device under the adjustment of the axial adjustment device is determined, the optimal position of the rotation process is found, and the vibration is optimized.
[0183] Please see Figure 11 In some embodiments, the method further includes:
[0184] S4241. When the second vibration data is less than or equal to the third vibration data, control the drive motor to drive the rotating shaft electromagnet to rotate a fourth preset angle based on the second direction, so as to drive the axial adjustment device, so that the axial adjustment device drives the balancing device to rotate along the second direction, and the fourth preset angle is twice the third preset angle.
[0185] S4242. After the rotating shaft electromagnet has finished rotating, acquire the sixth vibration data of the flexible rotating shaft;
[0186] S4243. When the third vibration data is less than or equal to the sixth vibration data, control the drive motor to drive the rotating shaft electromagnet to rotate by a third preset angle based on the first direction, and determine the final state of the axial adjustment of the balancing device.
[0187] Specifically, if the second vibration data is less than or equal to the third vibration data, the drive motor is activated, causing the drive motor to drive the rotating shaft electromagnet to rotate in the second direction by a fourth preset angle 2. This drives the axial adjustment device to rotate, causing the balancing device to rotate accordingly, and then shuts off the drive motor; it acquires the sixth vibration data A22, and determines the magnitude of the third vibration data and the sixth vibration data. If the third vibration data is less than or equal to the sixth vibration data, it turns on the drive motor, causing the drive motor to drive the rotating shaft electromagnet to rotate a third preset angle based on the first direction. Turn off the drive motor and confirm the final state of the axial adjustment of the balancing device. The first to fourth preset angles can be set according to actual needs, and are not limited here.
[0188] The above technical solution uses an axial adjustment device to control the balancing device to rotate gradually, and compares the vibration data before and after rotation to optimize the vibration data. This method can be adjusted in real time when the system containing the flexible rotating shaft is working, and can be adjusted according to the actual operating conditions to improve accuracy.
[0189] Please see Figure 12 In some embodiments, the method further includes:
[0190] S42431. When the third vibration data is greater than the sixth vibration data, control the drive motor to drive the rotating shaft electromagnet to continue rotating a third preset angle based on the second direction.
[0191] S42432. After the rotating shaft electromagnet has finished rotating, acquire the seventh vibration data of the flexible rotating shaft;
[0192] S42433. Update the third vibration data based on the sixth vibration data, and update the sixth vibration data based on the seventh vibration data.
[0193] Specifically, if the third vibration data A11 is greater than the sixth vibration data A22, it indicates that the adjusted vibration data has decreased. The drive motor is then activated, continuing to drive the rotating shaft electromagnet to rotate a third preset angle based on the second direction. Turn off the drive motor and continue to acquire the seventh vibration data A23 of the flexible rotating shaft. Determine the sixth vibration data as the third vibration data and the seventh vibration data as the sixth vibration data. Continue to judge the magnitude of the third vibration data and the sixth vibration data. Repeat the process of adjusting the rotation of the balancing device based on the second direction when the third vibration data is greater than the sixth vibration data, or adjusting the rotation of the balancing device based on the first direction when the third vibration data is less than or equal to the sixth vibration data, until the final position of the rotation of the balancing device under the adjustment of the axial adjustment device is finally determined.
[0194] If the above technical solution is effective in adjusting the vibration along the same direction, it will continue to be adjusted until the final position of the rotation of the balancing device under the adjustment of the axial adjustment device is determined, the optimal position of the rotation process is found, and the vibration is optimized.
[0195] Please see Figure 13 In some embodiments, the balancing device is laterally adjusted based on the second vibration data using a lateral adjustment device, including:
[0196] S411, Control the rotating shaft electromagnet to disconnect from the adjusting plate, and control the fixing module and the adjusting plate to be attracted and connected;
[0197] S412. Control the drive motor to drive the rotating shaft electromagnet to rotate by a first preset angle based on the first direction, so as to drive the lateral adjustment device, so that the lateral adjustment device drives the balancing device to move laterally.
[0198] S413. After the balancing device has moved laterally, acquire the eighth vibration data of the flexible rotating shaft.
[0199] S414. If the second vibration data is greater than the eighth vibration data, control the drive motor to drive the rotating shaft electromagnet to continue rotating by a first preset angle based on the first direction.
[0200] S415. After the rotating shaft electromagnet has finished rotating, acquire the ninth vibration data of the flexible rotating shaft;
[0201] S416. When the eighth vibration data is less than or equal to the ninth vibration data, control the drive motor to drive the rotating shaft electromagnet to rotate by a first preset angle based on the second direction, so as to drive the lateral adjustment device, so that the lateral adjustment device drives the balancing device to move laterally, and determine the final state of the lateral adjustment of the balancing device.
[0202] Specifically, the electromagnet of the rotating shaft is de-energized, causing it to disconnect from the adjusting plate; the fixing module is energized, causing it to magnetically connect with the adjusting plate; and the drive motor is activated, causing it to drive the electromagnet of the rotating shaft to rotate a first preset angle in a first direction. The rotating shaft electromagnet drives the lateral adjustment device to rotate. At this time, the adjustment disc does not rotate, the axial rotation device does not rotate, and therefore the balancing device does not rotate accordingly. However, the rotation of the lateral adjustment device causes displacement in the lateral direction of the balancing device, thereby driving the balancing device to move. After the rotating shaft electromagnet rotates by the first preset angle, the drive motor is turned off. Based on the vibration detection device, the eighth vibration data A4 is obtained. The magnitudes of the second vibration data and the eighth vibration data are compared. If the second vibration data is greater than the eighth vibration data, the drive motor is turned on, causing the drive motor to drive the rotating shaft electromagnet to continue rotating by the first preset angle in the first direction. The drive motor is then turned off, and the ninth vibration data A41 of the flexible rotating shaft is obtained. The magnitudes of the eighth vibration data A4 and the ninth vibration data A41 are compared. If the eighth vibration data is less than or equal to the ninth vibration data, it indicates that the vibration data in the previous adjustment step is less than the adjusted vibration data. The drive motor is then turned on, causing the drive motor to drive the rotating shaft electromagnet to rotate by the first preset angle in the second direction. This causes the balancing device to move laterally to the position of the previous adjustment step, and finally determines the final position of the balancing device's lateral movement under the adjustment of the lateral adjustment device.
[0203] The above technical solution utilizes a lateral adjustment device to detect the magnitude of vibration data during the lateral movement of the balancing device, thereby optimizing the vibration data during the adjustment process. The adjustment method is simple and effective.
[0204] Please see Figure 14 In some embodiments, the method further includes:
[0205] S4161. When the eighth vibration data is greater than the ninth vibration data, control the drive motor to drive the rotating shaft electromagnet to continue rotating by a first preset angle based on the first direction.
[0206] S4162. After the rotating shaft electromagnet has finished rotating, acquire the tenth vibration data of the flexible rotating shaft;
[0207] S4163. Update the eighth vibration data based on the ninth vibration data, and update the ninth vibration data based on the tenth vibration data.
[0208] Specifically, if the eighth vibration data is greater than the ninth vibration data, it indicates that the adjusted vibration data has decreased. The drive motor is then activated, continuing to drive the rotating shaft electromagnet to rotate by a first preset angle based on the first direction. The process involves rotating the lateral adjustment device on the balancing device, causing the balancing device to move laterally. After the balancing device finishes moving, the drive motor is turned off. The tenth vibration data A42 of the flexible rotating shaft is then acquired. The ninth vibration data is identified as the eighth vibration data, and the tenth vibration data is identified as the ninth vibration data. The magnitudes of the eighth and ninth vibration data are then compared. If the eighth vibration data is greater than the ninth vibration data, the lateral adjustment device is used to adjust the balancing device's movement in the first direction. If the eighth vibration data is less than or equal to the ninth vibration data, the lateral adjustment device is used to adjust the balancing device's movement in the second direction. This process continues until the final position of the balancing device under the adjustment of the lateral adjustment device is determined.
[0209] If the above technical solution is effective in adjusting the vibration along the same direction, it will continue to be adjusted until the final position of the balancing device under the adjustment of the lateral adjustment device is determined, the optimal position of the movement process is found, and the vibration is optimized.
[0210] Please see Figure 15 In some embodiments, the method further includes:
[0211] S4141. When the second vibration data is less than or equal to the eighth vibration data, control the drive motor to drive the rotating shaft electromagnet to rotate a fifth preset angle based on the second direction. The fifth preset angle is twice the first preset angle.
[0212] S4142. After the rotating shaft electromagnet completes its rotation, acquire the eleventh vibration data of the flexible rotating shaft;
[0213] S4143. When the eighth vibration data is less than or equal to the eleventh vibration data, control the drive motor to drive the rotating shaft electromagnet to rotate by a first preset angle based on the first direction, and determine the final state of the lateral adjustment of the balancing device.
[0214] Specifically, if the second vibration data is less than or equal to the eighth vibration data, the drive motor is activated, causing the drive motor to drive the rotating shaft electromagnet to rotate in the second direction by a fifth preset angle 2. This drives the lateral adjustment device to rotate, thereby moving the balancing device accordingly. The drive motor is then turned off. Eleventh vibration data A51 is acquired, and the magnitudes of the eighth and eleventh vibration data are compared. If the eighth vibration data is less than or equal to the eleventh vibration data, the drive motor is turned on, causing the drive motor to drive the rotating shaft electromagnet to rotate a first preset angle based on the first direction. The drive motor is then turned off, determining the final state of the lateral adjustment of the balancing device. The fifth preset angle can be set based on actual needs and is not limited here.
[0215] The above technical solution utilizes a lateral adjustment device to control the balancing device to move gradually laterally, and compares the vibration data before and after the movement to optimize the vibration data. This method can be adjusted in real time when the system containing the flexible rotating shaft is working, and can be adjusted according to the actual operating conditions to improve accuracy.
[0216] Please see Figure 16 In some embodiments, the method further includes:
[0217] S41431. When the eighth vibration data is greater than the eleventh vibration data, control the drive motor to drive the rotating shaft electromagnet to continue rotating by a first preset angle based on the second direction.
[0218] S41432. After the rotating shaft electromagnet completes its rotation, acquire the twelfth vibration data of the flexible rotating shaft;
[0219] S41433. Update the eighth vibration data based on the eleventh vibration data, and update the eleventh vibration data based on the twelfth vibration data.
[0220] Specifically, if the eighth vibration data is greater than the eleventh vibration data, it indicates that the adjusted vibration data has decreased. The drive motor is then turned on, and the drive motor continues to drive the rotating shaft electromagnet to rotate by a first preset angle based on the second direction. The drive motor is then turned off, and the twelfth vibration data A52 of the flexible rotating shaft is acquired. The eleventh vibration data is determined as the eighth vibration data, and the twelfth vibration data is determined as the eleventh vibration data. The magnitudes of the eighth and eleventh vibration data are then determined. This process is repeated when the eighth vibration data is greater than the eleventh vibration data, and the balancing device is adjusted based on the second direction using the lateral adjustment device. Alternatively, when the eighth vibration data is less than or equal to the eleventh vibration data, the balancing device is adjusted based on the first direction using the lateral adjustment device. This process continues until the final position of the balancing device under the adjustment of the lateral adjustment device is determined.
[0221] If the above technical solution is effective in adjusting the vibration in the same direction, it will continue to adjust until the final position of the balancing device under the adjustment of the lateral adjustment device is determined, the optimal position of the lateral movement process is found, and the vibration is optimized.
