Embodiment Construction

[0015] The specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] A double-split composite bridge structure, such as Figure 1-3 As shown, it includes a bridge body 9 and an anti-resonance device 10 arranged on the bridge body 9. The anti-resonance device 10 includes a pedal 1 at the top of the anti-resonance device 10, a generator 5 and an iron ball storage bin 6, the pedal 1, the generator 5 and the iron ball storage bin 6 are arranged sequentially from top to bottom, the generator 5 and the iron ball storage bin 6 are arranged on one side of the pedal 1, the upper end of the pedal 1 is slightly higher than the bridge deck, and the lower end of the pedal 1 is provided with a supporting block 2. The support block 2 is connected to the bridge body 9 through a spring, and the springs are arranged under the support block 2, and the number is 3. The support block 2 is provided with a connecting block...

Abstract

The invention provides a double-splicing type composite bridge structure, comprising a bridge body and an anti-resonance device arranged on the bridge body. The anti-resonance device includes a pedal,a generator and iron ball containers, wherein the lower end of the pedal is provided with a support block connected with that bridge body through a spring. A connecting rod is arranged on the supportblock, a transmission box is arranged on the connecting rod, a rotating disk is arranged on the generator shaft, the transmission box is connected with the rotating disk through a belt, an electromagnet is arranged on the generator, the electromagnet is electrically connected with the generator, an iron ball receiving bin is arranged below the electromagnet, an iron ball receiving bin is fixedlyconnected with the electromagnet, and an iron ball is arranged in the iron ball receiving bin. The double-splicing type composite bridge structure provided by the invention has the advantages of goodanti-resonance effect, simple structure and convenient use, that is, the iron ball is sucked up and dropped by the electromagnet, disorderly vibration is generated by the impact bridge body of the iron ball with different sizes, and the regular vibration brought to the bridge body by the passing vehicles is destroyed.

Description

technical field [0001] The invention relates to a bridge structure, in particular to a double-split combined bridge structure. Background technique [0002] Resonance refers to the phenomenon that the amplitude of the system increases significantly when the excitation frequency of the mechanical system is close to a certain natural frequency of the system. The excitation frequency at resonance is called the resonance frequency, which is approximately equal to the natural frequency of the mechanical system. On bridges, resonance is harmful, causing large structural deformation and dynamic stress, and even destructive accidents. [0003] In 1940, the 860-meter-long Tacomb Bridge in the United States collapsed due to resonance caused by strong winds. Although the wind speed at that time was less than 1 / 3 of the design wind speed limit, the actual anti-resonance strength of the bridge Did not pass the level, so the accident occurred. Resonance occurs when the vibration freque...
