184 Inspecting apparatus for attenuation member of moving blade JP24976498 1998-09-03 JPH11142296A 1999-05-28 PILERI PIERLUIGI
PROBLEM TO BE SOLVED: To correctly adjust a centrifugal force by a static system and enable simulation in a state close to an actual state, by arranging a hose expansible by the application of a pressure between a holding device and an attenuation member and inspecting the attenuation member. SOLUTION: An attenuation member 9 arranged below a platform 8 of a blade plate 6 is generally formed of a steel iron sheet and used to attenuate an amplitude of the vibrating blade plate 6 during driving. In order to improve amplitude attenuation efficiency, a preliminary test is conducted to a static system by a testing apparatus 1 and a weight and a rigidity are designed accordingly. Specifically, the blade plate 6 is vibrated by a vibrating apparatus and an elastic hose 10 is pressured, whereby a margin part 11 parallel to a groove 4 engaged with a projection 7 of the blade plate 6 is completely shut. As a result, a plane pressure is applied to the attenuation member 9 and blade plate 6. Accordingly, a centrifugal force up to approximately 6000N can be simulated to the attenuation member 9. If parameters (frequency, pressure) are adjusted, various kinds of attenuation members 9 can be simply exchanged and subjected to inspection. The amplitude of the blade plate 6 can be correctly measured by a laser, etc. COPYRIGHT: (C)1999,JPO

186 Method and apparatus for testing oscillation of fuselage during flight JP13325993 1993-06-03 JPH0643066A 1994-02-18 ARAN EDOWAADO SUTEIPURU; DANIERU MAREI UERUZU; ANDORIYUU RESURII JIYOODAN
PURPOSE: To test oscillation during flight by coupling a force generation actuator with a structure movable relatively at a shaking frequency, operating the actuator to apply a predetermined load at a predetermined frequency to the structure and then measuring the response of the structure. CONSTITUTION: A helicopter 11 has an electromagnetic actuator 22 integrated with each post 16, in order to input a power load to the fuselage 12 mounting an electronic actuator controller 23. One predetermined actuator 22 on the post 16 is then fed with a current through a connection member 24. In the operation, a cassette tape recorded with a specified test order is fixed to a cassette tape recorder 25. A required shaking force is inputted to one actuator 22, based on a signal from the recorder 25, and an actuator force reference signal is fed to an oscillation recorder 30. Structural response to the shaking force is sensed by a sensor 29 and recorded by the oscillation recorder 30 before being analyzed. Tests can be carried out in various testing orders, by replacing the cassette tape.
187 Vibration testing method JP411485 1985-01-16 JPS61164135A 1986-07-24 YOKOTA AKIHIKO
PURPOSE:To eliminate adverse influence on a vehicle, by finding an inverse transfer function from a transfer function, subjecting the inverse transfer function to Fourier- transformation, subjecting the multiplied value of the Fourier-transformed value and the inverse transfer function to inverse Fourier-transformation, and finding an initial excitation signal by multiplying the transformed value by an initial excitation factor. CONSTITUTION:The output signal of a detector 5 is measured and the transfer function of a system provided with a vehicle A, to which vibration is added from an exciter 1, and the detector 5 fitted to an optional position of the vehicle A is found by adding a vibration signal of a prescribed waveform to the exciter 1 of the system. Then an inverse transfer function is found from the transfer function and, at the same time, the inverse transfer function is Fourier-transformed. The Fourier-transformed value is multiplied by the inverse transfer function and the multiplied value is subjected to inverse Fourier-transformation and, furthermore, the inverse Fourier-transformed value is multiplied by an initial excitation factor. Thus an initial excitation signal is found. Since the initial excitation signal is found in such a way, the initial excitation signal is set to a low value and can be made closer to an actual value gradually by error correction. Therefore, the exciter 1 can be actuated without giving adverse influence to the vehicle A.
188 Temporary motion vibration-proof experimental device JP25519184 1984-12-03 JPS61132835A 1986-06-20 OKAMOTO SHIN; YAMAZAKI YUTAKA; NAKAJIMA MASAYOSHI; UENOSONO TAKASHI; KATO HIROTO; SENO TAISUKE; AIKI JIYUNICHI; MATSUSHITA TAKAYUKI
PURPOSE:To avoid the generation of an error of a higher order mode at the time of a response calculation, and to improve the experimental accuracy by giving an attenuation of the vicinity of the highest order mode of a response of a specimen as a larger value than others, as an attenuation term of a mathematical expression model of the specimen. CONSTITUTION:A displacement target value Xa of a specimen 1 is derived by executing a response calculation by a target value operator 5, based on a load quantity Fa of a displacement loading device 2a for giving a displacement of a prescribed vibration mode by applying a force to the specimen 1, and a mathematical expression model of the specimen 1 given from a constant setting device 6. In this case, to an attenuation term of the mathematical expression model, an attenuation factor of the vicinity of the highest order mode of a response of the specimen 1 is given as a larger value than others. Subsequently, from a displacement target value Xa and a displacement quantity Ya of the specimen 1, a displacement command value Va given to the specimen 1 is calculated by a displacement controller 7, and also based on a deviation of said value and a displacement quantity Wa of the displacement loading device 2a, a load quantity is controlled.
189 Apparatus for supporting object to be tested used in testing vibration test of cosmic structure JP24627284 1984-11-22 JPS61124838A 1986-06-12 KASAHARA AKIHIRO
PURPOSE:To obtain a test apparatus reduced in restriction in a gravity direction and added means effect, by hanging a cosmic structure by a long spring having a definite curvature. CONSTITUTION:One end of a long spring 1 having a definite curvature is fixed to a ceiling side support jig 2 and the other end thereof is fixed by wires 3. The wires 3 hangs up a structure 4 being an object to be tested in air. The support jig 2 consists of a fixed member 2a and a movable member 2b and the movable member 2b is displaced with respect to the fixed member 2a to regulate the length of each wire. Because the long spring 1 having the definite curvature receives almost constant tension regardless of a displacement amount, displacement is not restricted when a vibration test is performed. By this method, the same inherent vibration number and inherent mode as the vibration state in a cosmic space can be faithfully reproduced.
190 Vibration-characteristics testing apparatus of rotary machine JP21682383 1983-11-17 JPS60108728A 1985-06-14 KAMIYOSHI HIROSHI
PURPOSE:To ensure the actual measurement of the vibration characterictics of a rotary machine in operation safely, by providing a vibration-characteristics testing apparatus, which is provided with a vibration applying device, a vibration- applying force detector, vibration response detectors, and a vibration analyzing means. CONSTITUTION:In a rotary machine, a rotary shaft 12, to which a rotor under test 11 is fixed, is rotatably supported by bearings 13 and 14. An inertial-type hydraulic-vibration applying device 15 and a vibration-applying force detector 16 are attached on one bearing 13. Vibration response detectors 17 and 18 are attached in the vicinity of the supporting parts of the bearings 13 and 14 for the rotary shaft 12. A vibration analyzing device 20 analyzes the vibration characteristics based on a sine wave reference signal (a) generated by a control circuit 19, a vibration-applying-force signal (b) from the vibration-applying force detector 16, and vibratin response signals c1 from the vibration response detectors 17a and 18. The desired vibration characteristics of the rotary machine in operation can be actually measured safely and positively.
191 Testing method of rotary vibration of rotor having blade JP13183583 1983-07-21 JPS6024431A 1985-02-07 SHIBAUCHI HIROOKI; ARAKI MINORU; KITATANI KOUICHI; MASE MASATAKA
PURPOSE:To omit a steam apparatus and to perform safe operation without wetting, by blowing air as a vibration source to the blades of a rotating rotor with a pressure from a nozzle. CONSTITUTION:Air is blown from a nozzle 14 to blades 13 of a test rotor 10, which is supported by a bearing 15 in a vacuum chamber 11. Vibration is applied in this way, and a rotary vibration test is conducted. Since the air is used as a vibration applying fluid, a steam apparatus is not required. Since the steam is not used, the equipment is not wetted. The air is readily available and the operation is simple. Therefore there is no danger. Since the air has larger specific gravity than the steam, the effect of the vibration-application effect is large.

PURPOSE:To enable perfect restoration to the original status after finished test, by admitting water into a clearance between blade root and blade groove and fixing the root in the groove by freeze-solidification of water. CONSTITUTION:On both sides of a disc 3 on anti-water-leakage plate 5 is mounted, a hose 6 for freezer is supported by an arm 5a, water is introduced into a clearance between blade root 2 and blade groove 4, freezer is made to flow through the hose 6, allowing it to be injected from a small hole 6a for cooling a part of the vaneroot 2 and for causing freeze-solidification of water and thus, the blade root 2 is fixed in the blade groove 4 utilizing cubical expansion of ice and freezing action of water. As the freezer, liquefied nitrogen, etc. is used. Uniform blade root fixing condition becomes available and measurements can be obtained with less fluctuation. Upon finishing the measurement, water can easily be discharged and disc and blade root can be restored to the original condition in a perfect manner.

PURPOSE:To measure the sticking intensity at a connected part, by applying the exciting force inclreasing with the time lapses to give vibrations to the connected part, measuring the degree of distortion caused to a memeber and detecting a sudden displacement. CONSTITUTION:When the rotary frequency of a variable speed motor 8 is gradually increased, the momentum transmitted through a flexible shaft 7 increases to increase the vibration of an exciter 6. Accordingly, a connected shaft 2 vibrates, and a connected part 3 also vibrates. The degree of distortion of a plate 1 which is caused by the vibration of the part 3 is detected by an attached semiconductor distortion gauge 10, and the output of detection is displayed at a meter 9 via an amplifier 11 and a rectifier 12. A sudden change of the degree of distortion at the part 3 emerges in the form of a change of the degree of distortion of a component member. This degree of distortion becmes an index that shows tha sticking intensity of the part 3. At the same time, the output signal of the gauge 10 is amplified and supplied to a synchro scope 21 to be displayed in the form of a load waveflorm. Thus backlash can be decided for the connected part.
