Vibration Isolator and Damping Controllable Underwater Broadband Vibration Isolator

Abstract

The invention discloses a vibration isolating member and a vibration isolator. A vibration isolating member base, stress dispersion holes formed in the vibration isolating member base and fluid storage holes formed in the vibration isolating member base are included; the stress dispersion holes and the fluid storage holes are all through holes formed in the vibration isolating member base, and thehole opening directions of the stress dispersion holes and the fluid storage holes are the same; and a water guiding passage is further formed in the vibration isolation member base; and the water guiding passage is configured to be of a structure communicating with the stress dispersion holes and the fluid storage holes. The vibration isolating member is configured to be that mutual communication is realized, the through holes are reserved in the outer walls of the vibration isolating member, and the stress dispersion holes, the fluid storage holes and the water guiding passage can ensure that fluid components in the environment in which the vibration isolating member is located can freely enter and exit form holes inside the vibration isolating member along with shape changes of the vibration isolating member; and the shape changes and fluid flowing in the vibration isolating member improve the damping effect, and the design purposes of vibration reduction and noise reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of vibration reduction and noise reduction in water areas, in particular to a vibration isolator and an underwater broadband vibration isolator with controllable damping integrated with the vibration isolator. Background technique [0002] With people's continuous exploration and utilization of the ocean, the development and wide application of underwater equipment and precision instruments, the demand for vibration and noise reduction of the foundations that support and fix them is increasing, and the requirements for vibration isolation performance are gradually increasing. promote. For underwater instrument systems, on the one hand, whether the system can effectively isolate the micro-vibration in the low-frequency or ultra-low-frequency band is extremely important for improving the performance of the system; on the other hand, whether it can buffer the external vibration when it is subjected to mechanica...

AI Technical Summary

Problems solved by technology

For specific bearing requirements, in order to achieve a good vibration isolation effect in a wide frequency range, it is necessary to reduce the natural frequency of the system, thereby reducing the stiffness of the vibration isolator. However, the bearing capacity of the vibration isolator is often reduced accordingly, and the resistance The ability of mechanical shock is reduced accordingly, and it is easy to cause damage to the vibration isolation system and even the bearing equipment due to sudden collisions and other events
