Metal and rubber combined type vibration isolation device of space remote sensing camera and installation method of metal and rubber combined type vibration isolation device

Abstract

The invention discloses a metal and rubber combined vibration isolation device of a space remote sensing camera, which comprises a limiting cover plate, a rubber pad and a mandrel bottom plate, and is characterized in that the limiting cover plate and the mandrel bottom plate are adopted to compress the rubber pad, so that the rubber pad compresses a vibration-isolated object mounting foot, and vibration isolation is realized; a limiting structure used for further accurately controlling the compression amount of the rubber pad is further designed, ideal dynamic rigidity can be obtained in the radial direction and the axial direction of the vibration isolation device, on one hand, the good attenuation effect on high-frequency loads can be achieved, on the other hand, the low-frequency vibration response can be amplified and limited within a certain range, and meanwhile, the vibration isolation device has the good application prospect. The influence of the impact load on the remote sensing camera is effectively isolated; the metal and rubber combined mode is adopted, effective vibration isolation is achieved, meanwhile, the problem that the compression amount is difficult to control is solved, the compression amount of the vibration isolation device can be adjusted only by replacing the metal piece, operation is easy, and reliability is high. The invention further discloses an installation method of the vibration isolation device. The installation method is easy and convenient to operate and high in applicability.

Description

technical field [0001] The invention belongs to the technical field of space optical remote sensors, and relates to a space remote sensing camera vibration isolation device, in particular to a metal rubber combination vibration isolation device and an installation method, which are suitable for off-axis remote sensing cameras. Background technique [0002] Vibration isolation technology mainly refers to adding corresponding active or passive components in the vibration propagation path to reduce the energy transmitted from the interference source to the load. With the development of science and technology and the continuous improvement of people's living standards, vibration isolation technology is widely used in various fields. Usually, people divide vibration isolation technology into passive vibration isolation and active vibration isolation according to different vibration isolation components. The former is to take vibration isolation measures for vibration source equip...
