Description

Technical Field

[0001] The utility model relates to the technical field of vibration force detection, in particular to a multi-directional vibration force detection device. Background Art

[0002] With the rapid development of science and technology, the harmful effects of vibration in engineering structures and mechanical equipment have received increasing attention. Reducing the adverse effects of harmful vibration has been a research focus both domestically and internationally. Active control technology is an effective means of active vibration reduction. Specifically, the core of active control technology is the active control system. This system uses sensors to collect vibration signals from the controlled equipment. After processing by a processor, the system's active actuators output a reverse signal to offset the vibration of the controlled equipment, thereby achieving the effect of stopping vibration with vibration.

[0003] Active actuators are based on electromagnetic principles. The reciprocating motion of their internal actuator components cuts through magnetic flux lines, generating a simple harmonic electromagnetic force. This, combined with the internal elastic elements, forms a single-degree-of-freedom spring motion system, generating a simple harmonic output force. The output force of an active actuator is a key indicator of its performance. Therefore, before applying the active actuator, it is necessary to measure the output vibration force.

[0004] Since the elastic elements and guide structures inside the active actuator will change in different installation postures, the output force will be affected. However, the current detection device has a single detection direction during detection and can only perform unidirectional detection on the active actuator. As a result, when the active actuator is installed in other directions, the vibration force output will be different from the measured vibration force, which can easily affect the effect of vibration-stopping.

[0005] Therefore, the above problems need to be solved urgently. Utility Model Content

[0040] See also Figure 1 and Figure 2 In this embodiment, a multi-directional vibration force detection device is proposed for detecting the vibration force output by a vibration component 100 installed in different directions. The device includes a carrier 1 and a detection unit 2. The carrier 1 has multiple first mounting surfaces 11, and the multiple first mounting surfaces 11 have different orientations; the detection unit 2 is arranged on the first mounting surface 11, and the detection unit 2 has a second mounting surface 231 for mounting the vibration component 100, so that the vibration component 100 is in different installation postures, and the detection unit 2 is used to detect the vibration force output by the vibration component 100.

[0041] It can be understood that the detection part 2 is installed on the corresponding first mounting surface 11 as needed, so that the vibration component 100 can be installed on the second mounting surface 231 facing different directions, thereby simulating the vibration component 100 in different mounting postures. With this arrangement, the vibration force output by the vibration component 100 in different mounting postures can be detected under the action of the detection part 2, so that the vibration force output by the vibration component 100 in actual use can be consistent with the measured vibration force, thereby ensuring the vibration component 100 to have the effect of vibration-stopping.

[0042] It should be noted that the vibration component 100 in this embodiment refers to an active actuator. Of course, in some other feasible embodiments, the vibration component 100 may also be other components to be detected for vibration force, which will not be elaborated here.

[0043] Exemplarily, the carrier 1 is in the shape of a rectangular parallelepiped and has multiple first mounting surfaces 11, which are respectively a top mounting surface, a bottom mounting surface and a side mounting surface. When the vibration component 100 is set on the top mounting surface, it can simulate the forward installation of the vibration component 100. When the vibration component 100 is set on the bottom mounting surface, it can simulate the inverted installation of the vibration component 100. When the vibration component 100 is set on the side mounting surface, it can simulate the lateral installation of the vibration component 100.

[0044] In this embodiment, the detection unit 2 includes multiple groups of detection structures and signal processing modules. The multiple groups of detection structures are respectively arranged on different first mounting surfaces 11, and all have a second mounting surface 231; the signal processing module is electrically connected to the multiple groups of detection structures to read the vibration force output by the vibration component 100. It can be understood that a group of detection structures is correspondingly arranged on each first mounting surface 11. During the detection process, the same vibration component 100 can be detected by different detection structures, thereby ensuring that the vibration force output by the vibration component 100 in different installation postures can be detected. Of course, in some other feasible embodiments, multiple groups of detection structures can detect multiple vibration components 100 at the same time, thereby improving the detection efficiency. Among them, the signal processing module is preferably a digital instrument in the prior art.

[0045] Specifically, any detection structure includes a first transition plate 21, a pressure sensor 22, and a second transition plate 23. The first transition plate 21 is mounted on the first mounting surface 11; the pressure sensor 22 is arranged on the side of the first transition plate 21 facing away from the first mounting surface 11; the second transition plate 23 is arranged on the side of the pressure sensor 22 facing away from the first transition plate 21, and the side of the second transition plate 23 facing away from the pressure sensor 22 is the second mounting surface 231. It can be understood that the arrangement of the first transition plate 21 and the second transition plate 23 can disperse the pressure applied to the pressure sensor 22, avoid damage or failure of the pressure sensor 22 due to excessive local pressure, and thus improve the service life of the pressure sensor 22. In addition, the parallel arrangement of the first transition plate 21 and the second transition plate 23 can avoid deviations in the installation scheme of the vibration component 100.

[0046] In this embodiment, the natural frequency of the carrier 1 is greater than the vibration frequency output by the vibration component 100. This configuration can avoid resonance between the vibration component 100 and the carrier 1 when testing the vibration force, thereby ensuring the accuracy of the vibration force detection by the detection unit 2.

[0047] Further, see Figure 3 The multi-directional vibration force detection device further includes a first clamping member 3, a second clamping member 4, and a locking member. The carrier 1 is clamped between the first clamping member 3 and the second clamping member 4, and the locking member is used to fix the carrier 1 to the first clamping member 3 and the second clamping member 4. It can be understood that during the process of detecting the vibration force output by the vibration component 100, the first clamping member 3 and the second clamping member 4 can clamp the carrier 1, thereby increasing the natural frequency of the carrier 1, thereby further preventing the vibration component 100 from resonating with the carrier 1, and ensuring the accuracy of the vibration force detection by the detection unit 2.

[0048] Among them, the locking member is preferably a bolt. After the first clamping member 3 and the second clamping member 4 clamp the carrier 1, the bolt can keep the first clamping member 3 and the second clamping member 4 in the clamping state on the carrier 1, thereby ensuring the accuracy of the detection.

[0049] For example, each of the first clamping member 3 and the second clamping member 4 includes a base 31, a clamping plate 32, and a plurality of reinforcing ribs 33. The base 31 and the clamping plate 32 are arranged perpendicularly, and the plurality of reinforcing ribs 33 are arranged between the base 31 and the clamping plate 32. This arrangement ensures the connection strength between the first clamping member 3 and the second clamping member 4, thereby increasing the service life of the multi-directional vibration force detection device.

[0050] In particular, a clamping groove 321 is provided on the side of the clamping plate 32 facing away from the base 31. The clamping groove 321 is adapted to fit the carrier 1, and the two clamping grooves 321 have openings 322 arranged opposite each other. The carrier 1 is clamped between the two clamping grooves 321 through the openings 322. It is understood that the opposite sides of the carrier 1 can respectively fit with the groove walls of the clamping groove 321 through the corresponding openings 322, thereby ensuring the clamping performance of the first clamping member 3 and the second clamping member 4, thereby preventing resonance between the carrier 1 and the vibration component 100, and ensuring the accuracy of the detection.

[0051] Furthermore, the bottom of the carrier 1 is provided with a first bonding surface 12 and a second bonding surface 13, which are perpendicular to each other. The first bonding surface 12 is bonded to the bottom of the clamping groove 321, and the second bonding surface 13 is bonded to the clamping plate 32. This arrangement can increase the contact area between the carrier 1 and the first clamping member 3 and the second clamping member 4, thereby further ensuring the clamping performance of the first clamping member 3 and the second clamping member 4.

[0052] In this embodiment, the first clamping member 3 and the second clamping member 4 are spaced apart so as to reserve a side mounting surface for mounting a detection structure between the first clamping member 3 and the second clamping member 4, thereby enabling detection of the vibration force of the laterally mounted vibration component 100.

[0053] Since the vibration component 100 is heavy, when simulating the vibration component 100 in different installation postures, the vibration component 100 is usually installed using a hanger. However, it is inconvenient to install the vibration component 100 when it is installed upside down.

[0054] Based on the above, in this embodiment, the multi-directional vibration force detection device further includes a slide 5 for supporting the vibration component 100, and the slide 5 is slidably disposed between the first clamping member 3 and the second clamping member 4. It is understood that when the vibration component 100 is installed in an inverted manner, it is first placed on the slide 5. Under the action of the slide 5, the vibration component 100 can be moved to a position facing the bottom mounting surface and then installed on the bottom mounting surface. This arrangement can improve detection efficiency.

[0055] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
