Multidimensional metal shock absorber

Technical Field

A multidimensional metal shock absorber belongs to the field of metal shock absorber design.

Background

Large-scale precision machinery, electromechanical products such as aircraft engines and rocket engines are transported to a final assembly plant from a production plant, and need to be transprovincially, even reach destinations after long-distance transportation by means of intercontinental sea transport, aviation, railways, roads and other transport means, the aircraft engines and the rocket engines belong to large-scale precision machinery and electromechanical products, are high in price, and need to be provided with special transition transportation equipment for avoiding damage caused by vibration and impact in the product transportation process, the equipment has the functions of vibration reduction and impact resistance, and is designed for vibration reduction, and relates to the design of a transportation equipment shock absorber, wherein the axial damping and the radial frequency of a metal shock absorber are adjusted by independent mechanisms, the axial damping and the frequency of the conventional metal shock absorber are respectively adjusted by independent mechanisms, and the radial frequency is adjusted by independent mechanisms in the conventional metal shock absorber, the structure of the shock absorber is relatively complex, meanwhile, the vibration attenuation efficiency of the shock absorber is reduced due to the fact that a large amount of structural parts occupy limited space, the axial damping, the axial frequency and the radial frequency can be adjusted by one set of mechanism, the axial vibration attenuation component and the radial vibration attenuation component are combined into one, and the purpose of achieving unequal rigidity or equal rigidity in the axial direction and the radial direction according to needs is achieved.

Disclosure of Invention

The invention relates to a multidimensional metal damper, which comprises the following components:

1. the purpose of adjusting the axial damping or peak value transfer rate is achieved by controlling the pre-pressure of the outer diameter of the metal mesh pad and the inner diameter of the shell;

2. the purpose of adjusting radial frequency or rigidity is achieved by controlling the inner diameter of the metal mesh pad and the pre-pressure of the output shaft.

FIG. 1 is a schematic view of a multi-dimensional metal damper.

Detailed Description

1. Axial damping adjustment

The nominal size of the inner diameter of serial number 1 and the outer diameter of serial number 3 is equal to phi D and serves as an initial adjustment reference. When the axial peak value transfer rate of the shock absorber needs to be reduced, the outer diameter phi D of the serial number 3 is increased by 0.3-0.5 mm or an appropriate size, if the peak value transfer rate still needs to be reduced, the outer diameter of the serial number 3 is continuously and appropriately increased, and the process is continued until the peak value transfer rate meets the requirement, and similarly, the axial peak value transfer rate of the shock absorber needs to be increased, and the outer diameter size of the serial number 3 is appropriately reduced.

2. Radial frequency adjustment

The nominal size of the outer diameter of serial number 2 and the inner diameter of serial number 3 is equal to phi d and serves as an initial adjustment reference. When the radial frequency of the shock absorber needs to be reduced, the inner diameter phi d of the serial number 3 is increased by 0.3-0.5 mm or proper size, if the frequency still needs to be reduced, the inner diameter of the serial number 3 is continuously and properly increased, and the process is continued until the frequency meets the requirement, and similarly, the radial frequency of the shock absorber needs to be increased, and the size of the inner diameter of the serial number 3 is properly reduced.
