Abstract
The invention belongs to the technical field of vibration noise control, and particularly relates to warship vibration noise control. A large-load low-frequency air sac vibration isolator comprises an upper metal cover plate, a rubber air sac, a lower supporting seat, a high-pressure air pipe, an adapter and a ventilation nozzle. The upper metal cover plate is used for supporting an upper device. The upper part of the rubber air sac is connected with the upper metal cover plate through vulcanizing. The lower part of the rubber air sac is connected with the lower supporting seat through vulcanizing. The rubber air sac is used for accommodating high-pressure air and generating a lifting force to support the upper device. The lower supporting seat is used for supporting the rubber air sac and is connected with a floor. The high-pressure air pipe is in threaded connection with the adapter. The ventilation nozzle is in threaded connection with the high-pressure air pipe, and ensures the air tightness. The rubber air sac is filled with high-pressure air through the ventilation nozzle. On the basis of ensuring the air tightness of the air sac, the strength of the air sac is enhanced, the size of an air cavity is increased, and the bearing capacity of the air sac is improved effectively.
Description
Technical field
The invention belongs to Control Technique of Vibration and Noise field, noise control particularly to ship vibration.
Background technology
For high-performance ship, main employing machinery vibration isolation technique reduces the mechanical vibration transmission to pedestal, and it is main
Means are that equipment is used monolayer, bilayer or buoyant raft vibration isolation.Equipment is resiliently mounted on pedestal by vibration isolator, can realize 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 be the compressibility utilizing air to the nonmetal composite vibration isolator of the one realizing elastic reaction, there is variation rigidity, highly
The superior service behaviours such as adjustable, life-span length.The most alternative air-bag for ship vibration isolator model is less, and load
Scope is little, and natural 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 the most preferably solves big load, low-frequency vibration isolator performance
Change problem, lacks one and can meet big quality shipborne equipment load and frequency requirement, can meet again safety, reliability etc. and want
The air bag vibration isolator asked.
Summary of the invention
It is an object of the invention to: a kind of big load low frequency air bag vibration isolator is provided, solve big quality shipborne equipment well every
The problem shaken, can meet again safety, reliability requirement simultaneously.
The technical scheme is that a kind of big load low frequency air bag vibration isolator, it includes: metal top cover plate, rubber gas
Capsule, undersetting, high-pressure air pipe, adaptor and ventilation nozzle；
Metal top cover plate is used for supporting top equipment；
In rubber pneumatic bag, sulfuration has 3 metal rings, 3 metal rings to lay respectively at middle part and the rubber of rubber pneumatic bag
The both sides of glue air bag opening end；The sulfuration of rubber pneumatic bag upper, open end and metal top cover plate couples airtight, lower open end and under
Bearing sulfuration couples airtight, is consequently formed the chamber for accommodating gases at high pressure；
One end of high-pressure air pipe is tightly connected by adaptor with undersetting, makes high-pressure air pipe and chamber, the other end
It is tightly connected with ventilation nozzle, for being filled with gases at high pressure to chamber, produces lifting force and support top equipment.
During air bag work, external high pressure gas is from ventilation nozzle in high-pressure air pipe enters rubber pneumatic bag, and gas pressure acts on
Air bag inner surface, produces lifting force support air bag top equipment.
For the air bag vibration isolator that effective area is constant, typical natural frequency f is drawn by following formula:
Wherein: p0Interior pressure for air bag vibration isolator；paFor atmospheric pressure；A0For air bag effective area；V0For in air bag
Volume；
By above formula: the low frequency of air bag and A0、V0Relevant.
Beneficial effect: the present invention is ensureing that air bag strengthens gas by metal sulphide annulus in air bag on the basis of bubble-tight
Capsule intensity, expands air cavity volume, is effectively increased air bag bearing capacity, and air bag is intrinsic pressure up to about 2.6MPa, the highest carries about
400KN, air bag natural frequency is minimum can reach about 2Hz；And present configuration is compact, easy installation and removal, improves and executes
Work, the convenience of maintenance.
