Anti-vibration device and fiber grating demodulator

Abstract

The invention provides an anti-vibration device and a fiber grating demodulator. The device comprises a shell, vibration isolation strips, an n-shaped plate, support pillars and a vibration isolationbase; the shell comprises a shell body and a shell cover; the shell body is matched and connected with the shell cover so that a hollow structure is formed; the inside surface of the shell body is provided with a bracket; the n-shaped plate is fixed through the vibration isolation strips arranged on the bracket; and the support pillars are bridged on the n-shaped plate, and used for carrying equipment with anti-vibration requirements. The fiber grating demodulator comprises the anti-vibration device, connectors, an optical path module and a circuit module. According to the anti-vibration device and the fiber grating demodulator, by adopting the anti-vibration structure design that the vibration isolation strips are embedded, the anti-vibration performance of the anti-vibration device is greatly superior to the vibration reduction mode of fixed equipment of a mechanical bolted structure.

Description

technical field [0001] The invention relates to the technical field of anti-vibration of optical instruments and equipment, more specifically, to an anti-vibration device and a fiber grating demodulator. Background technique [0002] Equipment containing photoelectric modules has very high requirements for environmental stability. The shock and vibration outside the equipment will cause damage to the internal components and circuits of the equipment, poor contact and inaccurate measurement, resulting in the failure of the equipment to work normally. [0003] In the prior art, a mechanical bolt structure is usually used to fix the equipment. This method has almost no effect on equipment working in a static environment, but when the equipment is mounted on other objects in a vibrating environment, or when the equipment is transported or accidentally bumped or dropped during the movement of the equipment, mechanical It is difficult to meet the anti-vibration requirements of t...
