Embodiment Construction

[0022] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Such as Figure 1-Figure 3 As shown, a special-shaped broadband vibration isolation device includes an upper layer vibration isolator 1, an intermediate mass structure 2 and a lower layer vibration isolator 3. The intermediate mass structure is a special-shaped structure with a sinking middle part, and the middle part of the intermediate mass structure forms an upper concave surface and the lower convex surface, the top surface on both sides of the intermediate mass structure is the installation surface of the upper vibration isolator, and the bottom surface on both sides is the installation surface of the lower vibration isolator. The mounting surface of the lower vibration isolator.

[0024] The intermediate mass structure is made by welding the upper and lower panels through intermediate cr...

Abstract

The invention relates to a special-shaped broadband vibration isolation device, an installation method and a vibration isolator replacement method. The special-shaped broadband vibration isolation device comprises an upper-layer vibration isolator, a middle mass structure and a lower-layer vibration isolator, the middle mass structure is of a special-shaped structure with a sunken middle part, an upper concave surface and a lower convex surface are formed in the middle part of the middle mass structure, and the top surfaces of the two sides of the middle mass structure are upper-layer vibration isolator installation surfaces, the bottom surfaces of the two sides of the middle mass structure are lower-layer vibration isolator installation surfaces, and the upper-layer vibration isolator and the lower-layer vibration isolator are correspondingly installed on the upper-layer vibration isolator installation surfaces and the lower-layer vibration isolator installation surfaces. The structure is special-shaped, the modality reaches the standard, construction and maintenance are easy, and good vibration isolation performance is achieved in the full frequency band.

Description

technical field [0001] The invention belongs to the technical field of ship vibration and noise reduction, and in particular relates to a special-shaped broadband vibration isolation device, an installation method, and a vibration isolator replacement method. Background technique [0002] Civilian ships such as scientific research ships have higher and higher requirements for vibration and noise. In order to meet the design requirements of vibration and noise reduction for the whole ship, it is necessary to adopt vibration isolation design for the main vibration source equipment to realize the vibration attenuation function of the equipment. Since the oil pan of the main generator set is full in shape and sinks more than the mounting surface of the machine feet, and the layout height is fixed, the height reserved for the vibration isolation device between the oil pan and the inner bottom plate is very limited. Therefore, the intermediate mass structure needs to adopt a speci...
