SHIP CABIN ACOUSTIC SURFACE FINISHING

摘要

FIELD: transport. ^ SUBSTANCE: invention relates to machine building. Proposed cabin comprises metal built-up carcass consisting of bearing section structures accommodating sound-and-vibration insulating elements. Every said element includes layers of antivibration material on bitumen substrate, layer of sound absorbing material and perforated decorative panel. Air gap is formed between panel and said layer of porous sound absorbing material. Cabin carcass is jointed with ship bearing structures via antiviration system consisting of top and bottom suspensions. top suspension consists of two rubber bumpers. Bottom suspension consists of two bumpers made up of helical or conical springs. Sound absorbing material represents a plate from mineral cotton on basalt base stock faced by sound-transmitting material over its entire surface. Piece noise absorber is made up of rigid carcass secured to cabin ceiling by hooks or cables to comprises elements with sound absorbing material wrapped by said sound-transmitting material and arranged in perforated surface. ^ EFFECT: better antinoise and antivibration properties. ^ 2 cl, 4 dwg
