Abstract
The invention discloses a kind of vibration isolation device of aviation nacelle, comprise: floating platform (3), described floating platform (3) is arranged with at least three the first vibration isolators (2), is connected between described first vibration isolator (2) and described floating platform (3) by pipe link (1); Described floating platform (3) is provided with the second vibration isolator (4), described second vibration isolator (4) is fixedly connected with one end of adaptor (5), the other end of described adaptor (5) is fixedly connected with the fixed mount (6) of aviation gondola; The quantity of described first vibration isolator (2), described second vibration isolator (4), described pipe link (1) and described adaptor (5) matches.Invention increases vibration isolating effect, can the carrier high vibration that causes due to the factor such as air-flow or transmitting set of actv. isolation, ensure that the stable operation of aviation gondola and get image clearly; This isolation mounting structure is simple, is easy to realize, and meets the needs in practical application.
Description
Technical field
The present invention relates to isolation mounting, particularly relate to a kind of vibration isolation device of aviation nacelle.
Background technology
In use, because the factor such as air-flow or driving engine can cause carrier to produce high vibration, this, by affecting the image blurring of aviation gondola stable operation and acquisition, is unfavorable for follow-up data process to aviation gondola.
The isolation mounting used in current aviation gondola mostly is one-level vibration isolation, and concerning the carriers such as the more serious aircraft of vibration, the image ratio got is fuzzyyer, even if follow-up data processes but the precision of images got is not high yet.
Summary of the invention
The invention provides a kind of vibration isolation device of aviation nacelle, the arrangement increases vibration isolating effect, get the image of degree of precision, described below:
A kind of vibration isolation device of aviation nacelle, comprising: floating platform, described floating platform is arranged with at least three the first vibration isolators, is connected between described first vibration isolator and described floating platform by pipe link; Described floating platform is provided with the second vibration isolator, described second vibration isolator is fixedly connected with one end of adaptor, the other end of described adaptor is fixedly connected with the fixed mount of aviation gondola; The quantity of described first vibration isolator, described second vibration isolator, described pipe link and described adaptor matches.
The vibration of described first vibration isolator isolation 1-10HZ, the vibration of described second vibration isolator isolation more than 3HZ.
Described first vibration isolator and described second vibration isolator are specially: rubber shock absorber, spring vibration-isolator, metal isolator or air cushion vibration isolator.
The beneficial effect of technical scheme provided by the invention is: the present invention by being provided with the first vibration isolator and the second vibration isolator on floating platform, improve vibration isolating effect, can the carrier high vibration that causes due to the factor such as air-flow or transmitting set of actv. isolation, ensure that the stable operation of aviation gondola and get image clearly; This isolation mounting structure is simple, is easy to realize, and meets the needs in practical application.

Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below embodiment of the present invention is described further in detail.
See Fig. 1, Fig. 2 and Fig. 3, in order to improve vibration isolating effect, getting the image of degree of precision, embodiments providing a kind of vibration isolation device of aviation nacelle, this device comprises: floating platform 3,
Floating platform 3 is arranged with between at least three the first vibration isolator 2, first vibration isolators 2 and floating platform 3 and is connected by pipe link 1; Floating platform 3 is provided with the one end the second vibration isolator 4, second vibration isolator 4 being fixedly connected with adaptor 5, the other end of adaptor 5 is fixedly connected with the fixed mount 6 of aviation gondola; The quantity of the first vibration isolator 2, second vibration isolator 4, pipe link 1 and adaptor 5 matches.
During specific implementation, in order to get the image of good stability, the vibration of 1-10HZ preferably isolated by the first vibration isolator 2, and the vibration of more than 3HZ preferably isolated by the second vibration isolator 4.
During specific implementation, the first vibration isolator 2 and the second vibration isolator 4 can be rubber shock absorber, spring vibration-isolator, metal isolator and air cushion vibration isolator etc.
See Fig. 1, the embodiment of the present invention is described for four pipe links, 1, four the first vibration isolators, 2, four the second vibration isolators 4 and four adaptors 5.During practical application, pipe link 1 is connected with carrier (such as aircraft etc.), and aviation gondola is arranged on the fixed mount 6 of aviation gondola.
Achieved a fixed connection by tapped bore or other mode between second vibration isolator 4 and adaptor 5; Achieved a fixed connection by nut or other mode between the fixed mount 6 of adaptor 5 and aviation gondola.The embodiment of the present invention does not limit this.
It will be appreciated by those skilled in the art that accompanying drawing is the schematic diagram of a preferred embodiment, the invention described above embodiment sequence number, just to describing, does not represent the quality of embodiment.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
