Problems solved by technology
[0002] The airborne optoelectronic platform is the main equipment for aerial reconnaissance. It is used to obtain high-quality images. The vibration isolator is designed to reduce the vibration transmitted from the airframe to the airborne optoelectronic platform. It is connected to the airborne optoelectronic platform through a mounting core. In the current vibration isolator, in addition to axial and radial movement, the mounting core can also undergo deflection motion, resulting in angular displacement. Studies have shown that the angular displacement of the mounting core seriously affects the imaging quality of the airborne optoelectronic platform

The invention belongs to the technical field of vibration isolation design and particularly relates to a vibration isolator. The vibration isolator comprises an installation core, an axial vibration isolation component and a radial vibration isolation component, wherein the axial vibration isolation component is provided with an axial vibration isolation cavity, the installation core is arranged to run through the axial vibration isolation cavity and is capable of moving in the axial motion relative to the axial vibration isolation component, and the axial vibration isolation component limitsthe installation core to move in the radial direction; the radial vibration isolation component is provided with a radial vibration isolation cavity and a vibration isolation through hole communicating with the radial vibration isolation cavity; the axial vibration isolation component is arranged inside the radial vibration isolation cavity, one end of the installation core stretches out of the vibration isolation through hole, and the installation core is in clearance fit with the vibration isolation through hole; and the axial vibration isolation component can move in the radial direction relative to the radial vibration isolation component, and the radial vibration isolation component limits the axial vibration isolation component to move in the axial direction.
Description
technical field [0001] The application belongs to the technical field of vibration isolation design, and in particular relates to a vibration isolator. Background technique [0002] The airborne optoelectronic platform is the main equipment for aerial reconnaissance. It is used to obtain high-quality images. The vibration isolator is designed to reduce the vibration transmitted from the airframe to the airborne optoelectronic platform. It is connected to the airborne optoelectronic platform through a mounting core. In the current vibration isolator, in addition to axial and radial movement, the mounting core can also undergo deflection motion and produce angular displacement. Studies have shown that the angular displacement of the mounting core seriously affects the imaging quality of the airborne optoelectronic platform. [0003] Therefore, it is desirable to have a technical solution to overcome or at least alleviate at least one of the above-mentioned drawbacks of the pri...
