Precise vibration isolation device applied to large vacuum environment simulator

Abstract

A precise vibration isolation device applied to a large vacuum environment simulator comprises an outer vibration isolation device (1), a vibration isolator (2), a vibration isolation platform (3), atank penetrating outer device (4) and the vacuum environment simulator (7) are included; the outer vibration isolation device (1) is used for cutting down outer vibration; and the vibration isolator (2) is used for isolating vibration, and a precise vibration isolation function on a top end vibration isolation object (5) and a bottom end vibration isolation object (6) is achieved. The device solves the problems that an existing vibration isolation structure needs a large tower frame, testing is not convenient, the static vibration isolation requirement of a vertical large testing system cannotbe met easily, and solves the problem that the vibration isolation features of the upper portion and the lower portion of an existing hanging vibration isolation structure are not consistent, and reliability is high.

Description

technical field [0001] The invention relates to a precision vibration isolation device applied to a large-scale vacuum environment simulator, belonging to the field of anti-vibration precision measurement. Background technique [0002] At present, the vibration isolation device of the vacuum environment simulator has the following structure: (1) The bottom supports the vibration isolation structure, and the vibration isolator supports the vibration isolation platform under the environment simulator, and the environment simulator and the test system are installed on the On the vibration isolation platform, the test system is installed as a vibration isolation object directly or through the tower on the internal platform in the environmental simulator. This structure is the structure adopted by most environmental simulators in our country at present. This structure can weaken the impact of ground vibration on the test, but cannot weaken the impact of vibration from the enviro...
