Abstract

Tłumik przyszynowy, stosowany w celu obniżania emisji hałasu generowanego przez ruch kolejowy, zawierający odkształcalną otulinę określającą powierzchnię mocowaną do powierzchni szyny, elementy rezonujące znajdujące się w odkształcalnej otulinie i oddzielone od powierzchni mocowania, gdzie elementy rezonujące są zwymiarowane tak, aby wykazywały co najmniej dwie częstotliwości rezonansowe w zakresie częstotliwości drgań szyny, charakteryzuje się tym, że posiada otulinę (2), która zawiera wycięcia (2.1, 2.2) w postaci pustek powietrznych, umiejscowione zgodnie z kierunkiem drgań szyny (5).A rail muffler used to reduce noise emissions from railway traffic, comprising a deformable cover defining a surface attached to the rail surface, resonating elements contained within the deformable cover and separated from the mounting surface, wherein the resonant elements are sized to exhibit at least two frequencies resonant in the rail vibration frequency range, it is characterized by having a cover (2), which contains notches (2.1, 2.2) in the form of air voids, located in the direction of rail vibration (5).
