Mechanical Analysis of Soundproof Plate with Function of Wind Load Reduction and Experimental Verification Using a Full-scale Prototype

Soundproof walls are typically installed along viaducts to reduce trackside noise. Soundproofing systems are being built increasingly higher as train running speeds increase and the number of tall buildings near railway lines grows. This often leads to increase wind load and moments exerted on the walls. This study proposes a new type of soundproof plate systems that would not require drastic reinforcement of the viaduct. The system, called SSRW (soundproofing systems equipped with a mechanism of reducing wind load), deflects wind load, thus maintaining the viaduct safety in strong wind conditions. Magnetic attractive force controls the movement of the SSRW soundproof plate; magnetic field analysis was used to calculate the magnetic attractive force. The authors also performed load tests and wind tunnel tests, and they measured the SSRW's soundproofing properties according to Japanese Industrial Standards.
