Integrated sound and vibration isolation device for electromechanical equipment

Abstract

The invention provides an integrated sound and vibration isolation device for electromechanical equipment. The device comprises ship body bases, lower-layer vibration absorbers, a raft frame, a connecting transition boss, a connecting support, upper-layer vibration absorbers and a sound insulation cover, wherein the raft frame and the sound insulation cover are connected and fixed through the connecting transition boss and the connecting support; the raft frame and the ship body bases are connected and fixed through the lower-layer vibration absorbers; and the raft frame and the electromechanical equipment are connected and fixed through the upper-layer vibration absorbers. The integrated sound and vibration isolation device for the electromechanical equipment has the advantages that a vibration isolation function and a sound insulation function are integrated, the structure is compact, disassembly and assembly are convenient, reliability is high, environment adaptability is high, vibration and air noise transmission of ship equipment can be effectively inhibited, and a good solution way is provided for vibration noise control of the ship equipment and popularization and application of the air noise sound insulation cover.

Description

technical field [0001] The invention belongs to the technical field of vibration and noise control, and in particular relates to a sound-vibration integrated isolation device for electromechanical equipment. Background technique [0002] A large number of operating equipment arranged on ships is the main source of far-field noise and air noise in the cabin. Far-field noise affects the concealment of the ship, and air noise in the cabin affects the working and living environment of the crew. [0003] For the transmission path of machine foot vibration-base vibration-pressure-resistant body vibration-far-field acoustic radiation of marine equipment, floating rafts, double-layer vibration isolation devices or single-layer vibration isolation devices are usually used for vibration isolation to attenuate the vibration energy of equipment transfer. For the cabin air noise caused by the equipment, the sound insulation cover device can be used if the overall space permits; the air ...

AI Technical Summary

Problems solved by technology

Therefore, the separate arrangement of the vibration isolation device and the sound insulation cover will bring greater overall burden and implicated projects, and cannot provide more favorable conditions for cabin air noise control and vibration noise control

At present, the vibration isolation and sound isolation devices at home and abroad are independently designed, which cannot meet the needs of sound and vibration isolation at the same time.
