Distributed drive-by-wire pressure feedback compensation air flotation vibration control system

Abstract

The invention discloses a distributed drive-by-wire pressure feedback compensation air flotation vibration control system which comprises at least two supporting stiffness pre-buried plates which areuniformly distributed on the bottom surface of a stiffness platform. Pressure sensors are arranged on the lower portions of the supporting stiffness pre-buried plates, air flotation damping units arearranged on the lower portions of the pressure sensors, air inlets and air outlets are formed in the air flotation damping units, the air inlets are positioned above the air outlets, concrete foundation piers are arranged on the lower portions of the air flotation damping units, the pressure sensors are connected with data acquisition modules through data leads, the data acquisition modules are sequentially connected with drive-by-wire devices and pneumatic electromagnetic valves on the air flotation damping units through power supply modules, the system is simple and convenient to repair andmaintain, small in size and high in cost performance, and devices and components are high in matching performance.

Description

technical field [0001] The invention relates to the technical field of air-floating vibration control, in particular to a distributed wire-controlled pressure feedback compensation type air-floating vibration control system. Background technique [0002] At present, for the micro-vibration control of precision equipment with high requirements for environmental vibration, the air-floating passive control system and the active servo vibration control system are mainly used. During the working process of these two technologies, they are mainly oriented to the disturbance of stationary random vibration. For sudden non-stationary vibration disturbance, each has the following disadvantages: (1) The air-floating passive control system is not suitable for low-frequency vibration Occasions affected by impact and sudden high-energy broadband shock vibration. The basic frequency of the air-floating passive vibration control system is generally 1.5 ~ 3.0Hz, so for a specific type of pr...
