A Marine Impedance Variable Base Structure

Abstract

The invention provides a marine impedance variable base structure, and aims to overcome the shortcomings of an existing base structure in the aspects such as impedance adjustment, vibration reduction, noise reduction and application range. The marine impedance variable base structure comprises a base structure body, the base structure body comprises a fixed web, a public device installation panel and fixing support brackets, the fixed web is vertically connected with the public device installation panel, the fixed support brackets are uniformly arranged between the fixed web and the public device installation panel, groove channel is formed in the fixed web and the public device installation panel between two adjacent fixed support brackets, adjusting brackets are arranged in two mutually vertical groove channels, a detachable movable web is arranged on the outer end surface of the fixed web, a detachable movable panel is arranged on the public device installation panel. The marine impedance variable base structure has the advantages of simplicity, convenience in installation, flexible impedance adjustment, wide application range and the like, vibration transmitted by the device can be effectively restrained, and sound stealth performance of a ship is improved.

Description

technical field [0001] The invention relates to a variable impedance base structure for equipment installation, in particular to a variable impedance base structure for ships, which is a base structure capable of effectively reducing mechanical vibration and noise of marine equipment. Background technique [0002] The base structure is an important medium for the transmission of vibration and noise from mechanical equipment to the hull structure, and its impedance characteristics determine the proportion of vibration energy input from the vibration source to the structural members of the hull, which is one of the important design parameters. However, once the base structure is installed, its input mechanical impedance is determined and difficult to change. The existing vibration reduction and vibration isolation measures are to install expensive vibration reduction and vibration isolation devices between the equipment and the base, which not only increases the construction c...

However, once the base structure is installed, its input mechanical impedance is also determined and it is difficult to change

The existing vibration reduction and vibration isolation measures are to install expensive vibration reduction and vibration isolation devices between the equipment and the base, which not only increases the construction cost, but also puts forward new requirements for the equipment installation process, and its vibration reduction and vibration isolation effect It is also not particularly obvious due to the complexity of the equipment installation environment
