Air spring vibration isolation foundation with electromechanical damper

Abstract

An "air spring vibration isolation foundation with electromagnetic damper" is composed of a base body, an air spring system, an air supply system, a plurality of height control units, and a plurality of electromagnetic dampers. The electromagnetic damper consists of an iron core, a coil, an armature, a reversing switch and a controller. The coil surrounds the iron core, and the coil is connected to the output end and the signal input end of the controller through the reversing switch. The electromagnetic damper is both a damping force. The output actuator is also a measuring device for displacement and speed. The characteristic of the invention is that the damping ratio can be adjusted in real time according to the actual needs, the optimal damping ratio (0.2-0.25) of the vibration isolation system can be provided, and the transition process time can be more than doubled. , High reliability, long life, no pollution, strong adaptability to the environment. Using this damper, the vibration isolation performance of the air spring vibration isolation foundation is significantly improved, and the controllability performance is good.

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...
