Description
Technical Field
The invention belongs to the technical field of pipeline fastening and supporting on ships and ocean operation platforms, and particularly relates to a vibration isolation horse foot for pipelines.
Background
The vibration reduction of the pipeline system is a difficult problem of vibration reduction of the conventional ship auxiliary engine system and is a weak point of vibration control of the ship auxiliary engine system. The elastic horse foot is one of the main technical means of pipeline damping. Limited by size and weight, the existing elastic horse foot is mainly based on a single-layer vibration damping system, but the vibration damping effect is difficult to meet the requirements of low-noise ships.
In order to further improve the vibration isolation effect, the invention patent of China is that in 2019, 4 months and 19 days: elastic support vibration isolation device for marine pipeline system (publication No. CN 109654300A) discloses an elastic support vibration isolation device for marine pipeline system, which comprises three functional components: the pipe clamp vulcanizing assembly, the low-frequency vibration isolation assembly and the limiting assembly.

The vibration isolation structure adopts a double-layer vibration isolation structure, wherein the low-frequency vibration isolation element adopts 30-60-degree shear-shaped vibration-damping rubber, so that the vertical rigidity, the transverse rigidity and the longitudinal rigidity are reduced, the three-direction equal rigidity is realized, and the vibration isolation effect is excellent.
The rubber block has the main advantages of blocking, impact resistance and sound insulation performance of high-frequency structural vibration, but the rubber block is small in elastic modulus and is a nonlinear elastic material. Therefore, the natural frequency of the rubber block is high, and the vibration reduction efficiency of the low-frequency structure noise is low. And the influence of the pipeline on the equipment layer is mainly the solid structure transmission of the pipeline vibration, and the low frequency is mainly used. The vibration isolation device mainly performs vibration isolation through the low-frequency vibration isolation component, can still be regarded as a single-layer vibration isolation system actually, and is difficult to obtain effective improvement relative to the single-layer vibration isolation system in the aspect of vibration isolation effect. Therefore, aiming at the practical requirements of vibration reduction and noise reduction of low-noise ships, a double-layer vibration isolation horse foot with an intermediate mass body is urgently needed, and the vibration reduction effect of a pipeline is effectively improved.
