Air spring vibration isolation foundation with electromechanical damper

Abstract

Air spring vibration isolation foundation with electromechanical damper is composed of base, air spring system, air feed system, a plurality of height control units, a plurality of electromagnetic damper. The electromagnetic damper is composed of iron core, loop, gag bit, commutator switch and controller. The loop is winded on the iron core and connected to the output terminal of the controller and signal input terminal by the commutator switch. The electromagnetic damper is not only the output executing mechanism of the damper force and the measuring apparatus. The characteristics of invention is that: the damper rate can be regulated at real time depending on the necessity, the transient period can be increased more than one time and the optimum damping ratio of the vibration isolation system is 0.2-0.25. Using the damper, the air spring vibration isolation performance is obviously improved.

Description

technical field [0001] The invention relates to an electromagnetic damper type air spring vibration isolation foundation, in particular to an air spring vibration isolation foundation with ultra-low bandwidth. Background technique [0002] The air spring vibration isolation foundation currently used in engineering generally consists of a base body, an air spring system, an air supply system, multiple height control units, and multiple liquid dampers. The longitudinal damping ratio of the air spring vibration isolation foundation is generally less than 0.15, and the transverse damping ratio is very small. The effect of using the existing hydraulic damper in practical application is not obvious, and the damping ratio provided is generally less than 0.1 and cannot be adjusted. This kind of air spring vibration isolation system has large overshoot, slow vibration attenuation, long transition time, inconvenient use, and restricts the improvement of the performance of the vibratio...

Problems solved by technology

The longitudinal damping ratio of the air spring vibration isolation foundation is generally less than 0.15, and the transverse damping ratio is very small. The effect of using the existing hydraulic damper in practical application is not obvious. The damping ratio provided is generally less than 0.1 and cannot be adjusted.

This kind of air spring vibration isolation system has large overshoot, slow vibration attenuation, long transition time, inconvenient use, and restricts the improvement of the performance of the vibration isolation system.
