Embodiment Construction
[0018] Refer to the attached drawings, a high-load low-frequency airbag vibration isolator, which includes: metal upper cover plate 1, rubber airbag 2, lower support 4, high pressure air pipe 5, adapter 6, breather nozzle 9, wear plate 3, installation Screw 7, protective cover 8;
[0019] The metal upper cover plate 1 is used to support the upper equipment that needs shock absorption;
[0020] The rubber airbag 2 is vulcanized with 3 metal rings. The 3 metal rings are respectively located in the middle of the rubber airbag 2 and on both sides of the open end of the rubber airbag 2; the upper open end of the rubber airbag 2 is vulcanized and sealed with the upper metal cover plate 1. The lower open end is vulcanized and sealed with the lower support 4, thereby forming a chamber for containing high-pressure gas;
[0021] The upper part of the lower support 4 supports the rubber airbag 2 and the lower part is connected to the floor;
[0022] The high-pressure air pipe 5 and the lower su...

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 [0001] The invention belongs to the technical field of vibration and noise control, and particularly relates to ship vibration and noise control. Background technique [0002] For high-performance ships, mechanical vibration isolation technology is mainly used to reduce the transmission of mechanical vibration to the foundation. The main method is to use single-layer, double-layer or floating raft vibration isolation for equipment. The equipment is elastically installed on the base through the vibration isolator, which can realize the consumption of vibration energy of the equipment and achieve the effect of vibration isolation. Therefore, the performance of the vibration isolator will directly determine the vibration isolation effect. The airbag vibration isolator is a non-metallic composite vibration isolator that uses the compressibility of air to achieve elasticity. It has excellent performance such as variable stiffness, adjustable height, and long life. At...
