Abstract
Изобретение относитс к технической акустике, в частности к способам защиты от шума и вибрации операторов самоходных машин. Цель изобретени - повышение эффективности работы путем расширени частотного рабочего диапазона гашени колебаний Покрытие включает в себ плотный слой 1, пористый слой 2 и эластичную пленку 4, прилегающую к демпфируемой поверхности и выполненную в виде выступов 5 с образованием пустот. При этом поверхность пленки, прилегающа к пористому слою, перфорирована. Благодар расположению слоев и выполнению пленки обеспе- чиваетс одновременно шумо- и вибропоглощение. 2 з.п. ф-лы, 2 ил.This invention relates to technical acoustics, in particular, to methods of protecting noise and vibration of self-propelled machine operators. The purpose of the invention is to increase work efficiency by expanding the frequency operating range of vibration damping. The coating includes a dense layer 1, a porous layer 2 and an elastic film 4 adjacent to the damped surface and made in the form of protrusions 5 with the formation of voids. The surface of the film, adjacent to the porous layer, is perforated. By arranging the layers and making the film, noise and vibration absorption are provided at the same time. 2 hp f-ly, 2 ill.
