METHOD OF MAKING VIBRATION-ACOUSTIC DEVICE AND VIBRATION-PROOF DEVICE MADE USING SAID METHOD, AS WELL AS REINFORCING ELEMENT USED IN SAID DEVICE Russian patent published in 2016 - IPC F16F1/36 

FIELD: machine building.

SUBSTANCE: group of inventions relates to machine building. Method of making vibration-acoustic device includes formation of an air cavity in elastic-dissipative element made of rubber-like material. Cavity is closed with reinforcing elements. Reinforcing elements are made in form of convex elements. Elements at central part connected by common rod. Formed cavities are closed by a cover. Reinforcing elements an common rod are made integral from fibre glass-filled polyamide. Rod in the cross-section is given a cross-like shape with rounded edges. End of each reinforcing element is made with surface matched with surface of covered cavity. Vibration-proof device contains elastic-dissipative element from rubber-like material with cavity. Cavity has at least a pair of reinforcing elements. Each reinforcing element is made in form of convex mushroom solid body. Reinforcing element comprises a rod and at least two convex element.

EFFECT: wider range of insulated frequencies of vibration and sound.
