A micro-vibration control device for a towering suspension detection structure

Abstract

The invention provides a high-rise suspension detecting structure micro-vibration control device. The device comprises a steel rigid T-shaped table (1) which is a horizontal platform and is used for placing a radar inspected device and supporting a frame weight to maintain the balance thereof, a stopper system which comprises a class I stopper (2) and a class II stopper (4) and is used to preventimpact vibration and a sudden load from causing the steel rigid T-shaped table (1) to be separated from a supporting device to improve the stability. The class I stopper (2) is used to limit the relative position of the steel rigid T-shaped table (1) and an air spring in an air floating system (3). The class II stopper (4) is used to limit the relative position of a supporting rigid frame column (5) and an air spring in the air floating system (3). The device further comprises the air floating device (3) which is provided with 6 air springs to ensure stable horizontal face of the steel rigid T-shaped table (1), and a building structure basic floor (10) which is used to withstand the full load of a building and transfer the load to the foundation to realize anti-vibration.

Description

technical field [0001] The invention relates to the field of micro-vibration control of a detection structure, in particular to a micro-vibration control device for a towering suspension detection structure. Background technique [0002] For space-independent testing environments, such as electromagnetic shielding performance testing of radar and similar electronic components, etc., if it is necessary to provide a high-performance micro-vibration environment in a closed electromagnetic wave anechoic chamber in a space-independent testing environment, the electromagnetic shielding performance testing of radar components in a closed electromagnetic wave anechoic room When it is affected by random pulsation, it is necessary to provide micron-level or sub-nanometer-level vibration environment protection. [0003] At present, radar electronic components control the micro-vibration of the electromagnetic shielding room during the performance calibration test, which mainly uses a l...
