Description
Technical Field
The invention relates to a vibration reduction base based on metal rubber and a working method thereof.
Background
In recent years, the development of ships has been increasingly advanced toward higher speeds and larger sizes. With the consequent increased vibration and noise emissions, the main reason for this is that the power plant transmits vibrations to the hull. The ship base is used for bearing the load between equipment and a ship body and has the functions of supporting and preventing vibration, so that the vibration reduction and noise reduction level of the base influences the overall noise level of the ship, and the current effective means comprise the adoption of a vibration-resistant structure and the laying of damping materials.
The existing damping structure has a certain damping effect, but aims at the normal temperature. For the power cabin of the ship, the temperature in the cabin is higher due to the simultaneous operation of main heat sources of power equipment such as a diesel engine, a generator and the like, and the data show that the temperature of the environment in the cabin is up to 47 ℃ due to the simultaneous operation of two main diesel engines and two generator sets. The temperature to which the base, which is directly connected to the power plant, will be subjected will be higher. Meanwhile, the nuclear power ship power cabin inevitably has radiation problems. In these extreme cases, the properties of conventional rubber vary with them, and the operational reliability is not guaranteed.
