Embodiment Construction

[0032] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0033] Such as figure 1 and 2 As shown, the present invention includes an arc support seat 2, several support brackets 1 are evenly distributed on the lower surface of the arc support seat 2, and a single support bracket 1 is perpendicular to the lower surface of the arc support seat 2, and the arc The upper surface of the support seat 2 is attached to the damping rubber layer 3, and the upper surface of the damping rubber layer 3 is elastically mounted with an arc support plate 4. The arc support plate 4 includes an arc portion 401 that cooperates with the damping rubber layer 3. The upper edges on both sides of the two sides respectively extend outward along the horizontal direction to form a mounting portion 402 , and a plurality of first mounting holes 4021 are defined in the mounting portion 402 .

Abstract

The invention relates to a mounting base of a torsionally supported elastic damping platform, which comprises an arc support seat, several support brackets are evenly distributed on the lower surface of the arc support seat, and a single support bracket is connected to the lower surface of the arc support seat Vertical, the upper surface of the arc support seat is attached to the damping rubber layer, and the upper surface of the damping rubber layer is elastically installed with an arc support plate. The arc support plate includes an arc part that cooperates with the damping rubber layer. The upper edges respectively extend outward along the horizontal direction to form installation parts, and several first installation holes are opened on the installation parts. The present invention realizes the torsion support through the arc support plate and the arc support seat, consumes the energy generated by the vibration of the ship through the rubber damping layer, cooperates with the elastic connector to realize the elastic energy storage in the vibration process, and makes the vibration energy in the transmission path through the device. It is effectively reflected and absorbed, reducing the overall vibration and noise of the ship without affecting the reliability of the connection.

Description

technical field [0001] The invention relates to the technical field of ship vibration damping equipment, in particular to a torsionally supported elastic vibration damping platform installation base. Background technique [0002] In the past thirty years, with the continuous improvement of the main noise control level of ships, mechanical noise and propeller noise have dropped significantly, but there are still some noises that continue to affect the work of ships due to lack of control. One of the important manifestations is the vibration transmitted through the decking Noise has exploded as a percentage of the total noise component. [0003] The plank is a horizontal subdivision structure of the ship, which is connected to the hull and bulkhead. The vibration generated by the electromechanical equipment installed on the plank will be directly transmitted to the hull structure through the plank, forming vibration and underwater radiated noise. Due to the direct rigid conne...
