VIBRATION-, NOISE- AND HEAT-ISOLATING COATING Russian patent published in 2002 - IPC

FIELD: mechanical engineering; industrial acoustics. SUBSTANCE: floor coating for vehicles is combination of two vibroacoustic systems with soft- type deformation characteristics. Second type of flexibly dissipating element is made in form of cylindrical slots forming empty spaces from side of insulating surface by adjoining envelopes of elastomer material in form of arches with angle of opening equal to two tight ones and with axes parallel to each other. Opening of arches is pointed to outer layer made of elastomer material and is covered by shock absorbing diaphragms. Layer of elastomer material has projections pointed to insulated surface and arranged opposite to projections from outer side of coating. EFFECT: improved efficiency of coating within wide range of static loads, reduced vibrations and noises, provision of comfortable conditions for vehicle drivers. 3 dwg
