GLASING WITH IMPROVED VIBRATION-AND-SOUND-DAMPING PROPERTIES, METHOD OF ITS PRODUCTION AND METHOD OF BODY SOUND PROTECTION

摘要

FIELD: transport.;SUBSTANCE: invention relates to automotive industry, particularly, to glasing and acoustic protection of vehicle body. Proposed glasing comprises vibroacoustic channel, glass sheet and damping material element. Said channel comprises heavy element with weight related to length unit exceeding 0.05 kg/m and rigidly coupled with damping material element. Said damping material element is arranged between glass sheet and heavy element to feature modulus of elasticity smaller than 200 MPa at 20°C and at frequencies lower than 5000 Hz. Heavy element is jointed solely with the surface of damping material element with its opposite surface in contact with glass sheet surface. Aforesaid section is jointed with glasing. Said glasing is arranged in vehicle body, and absolutely independent thereof at channel level. Method of making said glasing consists in jointing glasing with vibroacoustic damping channel. Then, channel including element from damping material and heavy element are fitted in place. Then, cross-section area of element from damping material is selected. Then, channel is rigidly jointed to glasing over the surface of aforesaid element, opposite that jointed with heavy element. Proposed method of making glasing consists in using vibroacoustic damping glasing. Proposed method of protecting vehicle body cabin consists in using vibroacoustic damping glasing with vibroacoustic damping channel.;EFFECT: killed noise and vibrations.;20 cl, 2 dwg
