Remote sensor damping and vibration-isolation device improved based on bi-pod supporting mode

Abstract

The invention provides a remote sensor damping and vibration-isolation device improved based on a bi-pod supporting mode, and relates to the technical field of optical remote sensing vibration isolation. The remote sensor damping and vibration-isolation device comprises lower adapting supports, vibration isolation metal outer rods, vibration isolation metal inner rods and an upper adapting support, wherein the lower adapting supports are located in the same plane and horizontally fixed at the lower end of the remote sensor damping and vibration-isolation device; one end of each vibration isolation metal outer rod is fixedly connected with the corresponding lower adapting support, and the vibration isolation metal inner rods are fixedly mounted in the vibration isolation metal outer rods and extend out of the upper end faces, in the axial direction, of the vibration isolation metal outer rods; the ends, extending out of the vibration isolation metal outer rods, of the vibration isolation metal inner rods are fixedly connected; and the upper adapting support is fixedly mounted at the joint of the vibration isolation metal inner rods. The remote sensor damping and vibration-isolation device is high in vibration reduction efficiency and few in consumed system resource, functional separation of a rigid supporting structure and a damping and vibration reduction structure is achieved, the technical problem that the rigidity of a vibration isolation system is hard to maintain effectively is solved, and the temperature maintaining purpose of a working section of the damping and vibration isolation system is achieved.

Description

technical field [0001] The invention relates to the technical field of optical remote sensing vibration isolation, in particular to an improved damping vibration isolation device for remote sensors based on a bi-pod support mode. Background technique [0002] The vibration environment in the space launch process has the characteristics of a large number of levels and a wide frequency domain. During the delivery of aerospace precision optical remote sensors to the predetermined orbit, the vibration environment in the launch stage is quite harsh. The research report of the National Aeronautics and Space Administration (NASA TN D-6474, September, 1971.) pointed out that about 45% of aerospace equipment failures It is caused by the vibration during launch. With the rapid development of optical remote sensing, the demand for high-resolution cameras has become increasingly prominent. The development trend of large aperture and long focal length makes the scale of optical remote ...
