Description
Technical field
The utility model belongs to Control Technique of Vibration and Noise field, more particularly to ship vibration Noise measarement.
Background technology
For high-performance ship, main to adopt mechanical vibration isolation technique to reduce transmission of the mechanical oscillation to pedestal, which is main
Means are using individual layer, double-deck or buoyant raft vibration isolation to equipment.Equipment is resiliently mounted on pedestal by vibration isolator, is capable of achieving to setting
The consumption of standby vibrational energy, reaches the effect of isolation vibration.So, vibration isolator performance will directly determine vibration isolating effect.Air bag every
The device that shakes is realizing a kind of nonmetallic composite vibration isolator of elastic reaction, with variation rigidity, height using the compressibility of air
The superior service behaviour such as adjustable, life-span length.Air-bag for ship vibration isolator model alternative in the market is less, and load
Scope is little, and intrinsic frequency is higher, and installing space is big, it is impossible to meet the vibration isolation demand of big treatment device.
As can be seen here, it is excellent that current air-bag for ship vibration isolator does not preferably solve big load, low-frequency vibration isolator performance
Change problem, lacks one kind and can meet big quality shipborne equipment load and frequency requirement, and can meet security, reliability etc. again will
The air bag vibration isolator asked.
The content of the invention
The purpose of this utility model is：A kind of big load low frequency air bag vibration isolator is provided, big quality shipborne equipment is solved good
The problem of good vibration isolation, while and can meet security, reliability requirement.
The technical solution of the utility model is：A kind of big load low frequency air bag vibration isolator, it includes：Metal top cover plate, rubber
Glue air bag, undersetting, high-pressure air pipe, adapter and ventilation nozzle；
Metal top cover plate is used for supporting top equipment；
In rubber pneumatic bag, sulfuration has 3 metal rings, and 3 metal rings are respectively positioned at the middle part of rubber pneumatic bag and rubber
The both sides at glue air bag opening end；Rubber pneumatic bag upper, open end couples closed with the sulfuration of metal top cover plate, and lower open end is with
Bearing sulfuration connection is closed, is consequently formed the chamber for accommodating gases at high pressure；
One end of high-pressure air pipe is tightly connected by adapter with undersetting, makes high-pressure air pipe and chamber, the other end
Be tightly connected with ventilation nozzle, for gases at high pressure being filled with to chamber, produce lifting force and support top equipment.
When air bag works, external high pressure gas is entered in rubber pneumatic bag from ventilation nozzle Jing high-pressure air pipes, and gas pressure is acted on
Air bag inner surface, produces lifting force support air bag top equipment.
The air bag vibration isolator constant for effective area, typical intrinsic frequency f are drawn by following formula：
Wherein：p0For the interior pressure of air bag vibration isolator；paFor atmospheric pressure；A0For air bag effective area；V0For in air bag
Volume；
By above formula：The low frequency and A of air bag0、V0It is related.
Beneficial effect：The utility model ensure air bag it is bubble-tight on the basis of by air bag metal sulphide annulus it is strong
Change air bag intensity, expand air cavity volume, effectively increase air bag bearing capacity, air bag internal pressure can be held up to 2.6MPa or so, highest
About 400KN is carried, air bag intrinsic frequency is minimum to can reach 2Hz or so；And the utility model compact conformation, easy installation and removal,
Improve construction, the convenience of maintenance.
