Embodiment Construction

[0030] Embodiment 1 of the anti-resonance damping method of a structure is as Figure 1~4 As shown: the anti-resonance damping device 4 is connected in series to the end of the structural member 7. The structural member in this embodiment is a cable 7 connected to the iron tower 1. The length of the cable 7 is extended along the front and rear direction. At least one end of the cable passes through the anti- The resonance damping device is connected with the corresponding iron tower. The cable 7 constitutes a structural member to be prevented from generating a resonance phenomenon.

[0031] The anti-resonance damping device 4 includes a device housing 8. The anti-resonance damping device 4 also includes a first connecting piece 3 provided with a first connecting structure 2 and a second connecting piece 5 provided with a second connecting structure 6. The first connecting structure 2 and the second connecting structure 6 are both hinged connecting structures, the hinged conne...

Abstract

The invention relates to an anti-resonance damping method for a structural body. The method comprises the following two conditions that 1, an anti-resonance damping device is connected in series with the end part of a structural member or one end of the anti-resonance damping device is connected between the two end parts of the structural member, when the structural member vibrates in opposite directions, the damping structure of the anti-resonance damping device provides damping forces of different magnitudes, so that the effective length of the resonance damping device participating in vibration of the structural member is changed or the effective vibration length of the structural member during reciprocating vibration is changed. According to the anti-resonance damping method for the structural body, the technical problem that in the prior art, a resonance phenomenon is likely to happen to corresponding structural members is solved.

Description

technical field [0001] The invention relates to an anti-resonance damping method for a structure in the field of structural safety. Background technique [0002] Resonance is a very high-frequency technical term in physics. It refers to the situation where a physical system vibrates at a specific frequency with a larger amplitude than other frequencies. These specific frequencies are called resonance frequencies. At the resonant frequency, small periodic vibrations can produce large vibrations because of the kinetic energy stored in the system. Because the resonance phenomenon will produce relatively large vibration, it will cause relatively large damage to the corresponding structure, so the human recovery technology utilizes or attempts to avoid the resonance phenomenon. [0003] Resonance phenomenon is common in real life. For example, in the field of transmission lines, the two ends of the cable are connected between two adjacent iron towers. The cable and the iron towe...
