Background
With the development of urban construction, the number of urban viaducts is increased year by year, but when automobiles run at high speed on the viaducts, large noise is generated. One part of noise comes from the friction between the tire and the bridge floor, the other part of noise is that the tire can be suspended in the air instantly when the automobile passes through the expansion joint, the expansion joint is impacted, the instant noise is formed, the sound wave generated when the automobile passes through the expansion joint at a high speed can also form wind noise in the beam body seam and transmit the wind noise downwards, the noise volume is large, and the noise is also the main source of the noise generated when the automobile runs on the overhead ground.
At present, most bridge expansion joints adopt an analog expansion joint and a comb-tooth expansion joint. Both types of expansion joints do not have the function of vibration and noise reduction. The modulus formula expansion joint is the linear type, and the opening is big, and the car divide into when passing through the seam body: the lower expansion joint, the span expansion joint and the upper expansion joint. According to research, when the tire completely spans the seam width, the tire is directly contacted with a right-angle steel plate of a seam body, the wheel load is gradually increased, the generated vibration is maximum, and the generated noise is also maximum. When two tires are simultaneously contacted with the seam body right-angle steel plate, the generated vibration is larger than that generated by the contact of a single tire and the seam body right-angle steel plate, and the formed noise is also large.
The patent of publication No. CN207878270U discloses a type of making an uproar expansion joint falls, adopts the wave form board and falls the case of making an uproar, but this wave form board wave form is whole for the linear type, and when the tire passed through the wave form board, two wheels still can have the condition of passing through the expansion joint simultaneously, still can produce great vibration, do not fundamentally solve the problem.
