Abstract

Przedmiotem wynalazku jest bariera wibroakustyczna i sposób jej regulacji. Bariera wibroakustyczna charakteryzuje się tym, że zbudowana jest z powtarzalnych komórek podstawowych (2), które mają cienkościenne ściany o kształcie geometrycznym, i umiejscowionego w przestrzeni każdej z nich rezonatora (3), który składa się z masy elementu rezonującego (m) połączonej z co najmniej jednym elementem sprężystym (4) mocowanym do ściany komórki podstawowej (2), przy czym rezonator (3) komórki podstawowej (2) ma stałą lub zmienną charakterystykę dynamiczną i akustyczną w zmiennym polu naprężeń, natomiast ilość (n) komórek podstawowych (2) zależna jest od uzyskania kształtu i wielkości bariery, przez co wymiary geometryczne bariery wibroakustycznej są wielokrotnością wymiarów komórki podstawowej (2).The subject of the invention is the vibroacoustic barrier and the method of its regulation. The vibroacoustic barrier is characterized by the fact that it is made of repetitive basic cells (2), which have thin-walled walls of geometric shape, and a resonator (3) located in the space of each of them, which consists of the mass of the resonant element (m) connected to at least one elastic element (4) attached to the base cell wall (2), with the resonator (3) of the base cell (2) having constant or variable dynamic and acoustic characteristics in a variable stress field, while the number (n) of the primary cells (2) depends on obtaining the shape and size of the barrier, so the geometrical dimensions of the vibroacoustic barrier are a multiple of the dimensions of the primary cell (2).
