Abstract
Description
Claims (2)
- 철도 레일; 및상기 레일의 웨브 양측면에 상기 레일 길이방향으로 부착되고, 철도차량 주행시 바퀴와 레일의 상호접촉으로 발생되는 소음을 반사시키는 반사부가 다수개 형성되는 댐핑부재를 구비하여, 철도차량 주행으로 발생되는 소음이 상기 반사부에 접촉되어 반사시 본래의 파장이 변조된후 반사부에 반사되지않고 수음지로 향하는 원소음의 음파를 교란시켜 소음에너지를 저감시키는 것을 특징으로 하는 철도레일 소음감소용 댐핑부재.
- 청구항 1에 있어서, 상기 댐핑부재의 반사부는 좌우방향의 수평칸막이에 의해 상하 2열로 형성되고 상하방향의 수직칸막이에 의해 길이방향으로 연속적으로 반복형성되며, 상기 댐핑부재는 PVC, 고무재, 목재중 어느 하나로 형성된 것을 특징으로 하는 철도레일 소음감소용 댐핑부재.
