Description of the invention (1) The present invention relates to an active control method of a suppressor "vibration (including structural bodies and weapons), which is based on the elasticity" vibration theory of vibration Sister Qi, by controlling the movement of any point, the effect of suppressing the vibration of the whole thing is achieved. When the mutual vibration occurs due to the external force due to the external force, if its vibration is large, it will easily cause fatigue of the material or the damage of the object. Therefore, K must be added to suppress and ensure the safety of structures or tools. The control of physical vibration can be divided into passive control and active control. The passive control method increases the damping of the object "or adds an absorber (absorber) M to consume the vibration generated by it. Yes • There is also an increase in the stiffness K of the object S3 to withstand strong vibrations. The active control law system applies external force or other external energy and gradually reduces its vibration. However, the active control method currently used requires the vibration analysis and multi-point measurement of the object crow *, and then the external force of multi-central control is applied to the object. Due to the errors in analysis and calculation and the external force required, it is not easy to control accurately. It is often because of active control that new vibrations other than the original dynamics are excited. This is commonly referred to as overflow vibration (spillover). Linear Vibration Theory • The object "being subjected to external forces, produces a state of forced vibration with a certain vibration state. And from the vibration state of any point on the object limb, a corresponding vibration type force (state-dependentvibrat 〇ryf 〇 "ce) can be determined. If this pair of vibration type force is placed at this point, the object" all vibration " ; If you can add another dynamic control force (dynamical control force) at the same point on the object film, M cancels the vibration-type force at this point * and generates a control vibration (state of controlled aotion) that is inverse to the applied vibration ) -4 * line, 215062 Λ f! U 6 Economic Lang Gyangyang "-Aux;), i " t Zuoshe Yinhong V. Description of invention (2), you can suppress the object "this point and all its vibration. Based on This theory • The purpose of the present invention is to provide an active control method for vibrating objects, using a sister ’s active control system • No need to go through vibration analysis and calculation of object M and multi-viscosity measurement The dynamic control force * of the opposite state of the state force can control the vibration of the object. Another object of the present invention is to provide a vibrating object "active control method, which actively controls the control system due to a closed control system The movement of the previous sticky product to achieve the suppression of the vibration of all objects «The closed-loop control system includes: a force placed on an object adjacent to the sticky body and having the same position of the same state ® transducer (electrodynamic) transducers) * —A signal adjustment and control device formed by an inverting amplifier and an adjustable irrigation source supplier. The force transducers include sensors and actuators * The sensor is connected to the input terminal of the inverting amplifier, the output of the inverting amplifier is connected to the actuator, and Yiya supplies the energy of the box of the inverting amplifier. When the sensor mounted on the object detects the object After turning to a vibration state of an external force, an energetic signal representing the vibration-type force is generated. This electric signal is inverted by an inverting amplifier and amplified by a figure method * to the actuator mounted at the same point on the object. The dynamic control force generated by the actuator can be applied at this point in reverse control operation. The sum of the external force management and the control of the embedding is the actual embedding of a small amplitude object. Another object of the present invention is to provide Active control of a vibrating object Method, the power applied to the system by the added dynamic control force can be used to control the vibration of the object by canceling the vibration energy * of the object.

And have the same vibration state. When the vibration of a certain point on the object 18 is received by the sensor 10, it is converted into a dagger signal, and the gain control of the hydroxy inverting amplifier 14 is the impedance. The ratio of Z〇 to the input impedance (Zo / ZdK determines its amplification rate) and is supplied to the actuator 12 by the power supply 16 to output an inverted dynamic control force M to suppress the vibration at this point , And achieve the vibration of the inhibitor Ya 18. Figures 2 to 8 are the experimental results of using this system to control a structure (cantilever beam), which is used to illustrate the effect achieved by the present invention in the application of Yin. The test results were completed by two aluminum beams of different lengths, the dimensions of which were 500 length X 29.8 width X 32 thickness (mm) and 400 length X 29.8 width X 3.2 thickness (m) respectively (under Μ Α Beam and Β beam are shown.) As shown in FIG. 2, each cantilever beam 20 is fixed on a base 22, and the depth of embedding into the base 22 is 100 mm, so that it extends out of the base 22 The lengths are 400 and 300 mm, respectively, and M ensures the boundary conditions of the cantilever beam 20. —Sister exciter 21, which can be made of piezoelectric ceramic, and its dimensions are 2 5. 4 length X 9.9 width X 1.0 thick ( Mm), which are installed on the top and bottom surfaces of the cantilever beam 20. The mao beam 20 is intended to be assisted by external forces Signals (such as harmonics, tunneling, periodic randomness, pulse signals, etc.) generated and amplified by a generator (not shown), which is fed back to the exciter 21 to excite the cantilever beam 20 to generate vibrations. The arm 20 inspires most of the most large-scale spiders used in the Bffl family WiMCNSMM specification (2 丨 0x297 ambassador) 2150 ^ ΛΓ Λ fi W 6 V. Description of the invention (5) in Ml ifi first note t-item Sun m% This η is low in normal transverse state, preferably, the exciter 21 is placed in the central span of the suspended beam 20. At the free end of the hanging beam 20, a vibration detector 23 is placed. The vibration detector 23 may be an accelerometer, speed or displacement sensor, and is connected to the oscilloscope 24, the analyzer 25 and the recorder 26. The multiplier sensed by the vibration detector 23 can be displayed by the oscilloscope 24 to indicate the vibration of the cantilever beam 20. The analyzer 25 can determine the response spectrum of the vibration and record the result in the recorder 26. In this test, the synthetic mechanism of A beam is measured by non-contact vortex and flu sensor. B beam is measured by acceleration gauge, and the vortex and flow sensor is based on the use of magnetic force. Formed the galvanic system of induced electrical charge and object distance. In addition, the displacement response of the light mine displacement sensor (Fotonic sensor) can also be used. It can be known that although different devices are used to obtain the vibration signal, it does not affect the results obtained by the active control of the present invention. .¾ 济 郎 屮 央 # quasi / (.

The dimensions are 25.4 long X 9.9 wide and 1.0 thick (mm). When the pressure is applied to the pressure piece, the The pressure pads are subject to the expense, and the strain of the chimney depends on the polarization direction of the pressure material. For example, piezoelectric plates are used as actuators. 12 · To strengthen its action | two pressure pads can be installed, one of which is located The top surface of the cantilever beam 20 and the other are located on the bottom surface of the cantilever beam 20 * and the electric field of the compression plate is reversed, so when one of the plates produces a tensile stress, the other plate generates a compressive strain, so the suspension The bending moment of the cross section of beam 20 becomes twice. If the pressure piece is used as a sensor to detect the bending moment of 10M, it can also be installed on the opposite side of the cross section of cantilever beam 20. Since the top and bottom of the beam are « Wish to change the permanent state to maintain the inverted state, so the pressure output of each sensor 10 is also exactly 8 ^ paper 5 civilian scale happy use in a sleepy home standard (CNS) Τ Ί specification (210x297 public) V.

Amplifier action PZT-5H at the time of the actuator 12, and put it into the vibration mode to the actuator to suppress the vibration pressure. Theoretically, due to the actual force control force, therefore, for the joints, for example, at the time, the maximum is close to its roots, draw 3 tables, and suddenly cut to 0.75 seconds Figure 3 (1) the unity index; 3. As long as each sensing is different, so, and each of the forces 12M of the force to the arm beam 20 is moved. Vibration of the voltage is applied at a single time point. Because and because of the sense of all the chess moves The position of the position of the curvature in the long-sleeved direction should be placed when the exciter is broken, and the time record curve is used as the output of the bender 10 of / 3 is fed back to the cantilever beam 20. , And the top and bottom surfaces of the stalk arm 20 are installed with four actuators 12 and the sensor 10, which are parallel to the top and bottom surfaces respectively. The sensor 10 measured on behalf of its The signal is inverted and amplified by the inverting amplifier 14 The degree of control depends on the feedback to the actuator 12. It is controlled by adjusting the gain of the inverting amplifier 14. You can control the motion of all points of the vibration structure. However, in order to obtain the maximum control effect, you must choose 逋The invention uses the sensor to detect the vibration. The signal obtained by the K generator is the superposition of all vibrations. For the purpose, the sprinkler and the actuator should not be placed close to the area where high longitudinal strain can be generated. The cantilever beam's impact is proportional to the curvature of the tree and the beam vibrates at its root, so the actuator and sensor are installed everywhere (as shown in Figure 2). 29.65 Hz, the source of mildew under resonance, and the resulting time-domain initial displacement and velocity of the beam after 0.75 seconds of vibration.

Description of the invention (3) Through experimental results It is known that the present invention utilizes two sensing and actuating forces with the same linear inverting output and input aiming system "Transducer * No Phantom Vibration Analysis and Multi-Point Measurement of Objects • It is not necessary to distinguish the various stages of vibration In case of filtering out, the engraved signal representing the vibration type force directly measured by the sensor * is inverted and amplified by the inverting amplifier, and then fed back to the actuator mounted on the object, which is generated by the actuator Dynamic control force • Controlling a point of embedding on an object, you can control the vibration of the object * and it is not an individual control for a limited chess position, so you can see the overflow of vibration control. The structure and features of the present invention are more apparent from the detailed description and circled above. It should be understood that the sensing and actuating power transducers in the present invention are not limited to the piezoelectric used in this example The materials should include other magnetic isoelectric transducers. In this example, the force transducer is a juxtaposed sensor and actuator * used to control the bending vibration of the beam. The present invention includes other forces on the object that have a viscous phase and have the same vibration state. "Sister of the transducer, use K to control the vibration of the object such as stretching and torsion. These examples are only used to illustrate the better exploration of the present invention as a barking state. • It is not intended to limit the scope of the invention. Any improvements and changes that do not deviate from the spirit of the present invention belong to the present invention.
