Magnetic suspension type intelligent vibration isolation device

Abstract

The invention provides a magnetic suspension type intelligent vibration isolation device. The magnetic suspension type intelligent vibration isolation device comprises a substrate, an excitation coil, a lower sleeve, an upper sleeve and a floating type piston which are all sequentially arranged from bottom to top. A magnetic core is arranged on the substrate, the excitation coil is sleeved outside the magnetic core, the lower sleeve is connected with the substrate, the magnetic core and the excitation coil are sleeved in the lower sleeve, silicone oil is placed in the upper sleeve, a waterproof breathable film adhered to an inner wall of the upper sleeve is arranged above the silicone oil, a permanent magnet is arranged at the bottom end of the floating type piston, and the lower portion of the floating type piston penetrates through the waterproof breathable film to be placed in the silicone oil. The magnetic suspension type intelligent vibration isolation device is a mixed vibration control device used for precise vibration isolation and can be applied to vibration isolation of a precise instrument platform or various micro-vibration isolation environments.

Description

technical field [0001] The invention belongs to the field of hybrid vibration control, and relates to a vibration isolation and damping device applied to precision instrument platforms or various micro-vibration isolation and vibration isolation environments. Background technique [0002] With the development of modern science and technology, the high-tech industry and its products are growing rapidly, and the requirements for the working environment are constantly increasing. For example, the size of materials and particles processed by nanotechnology is below 100nm, and the working environment must be extremely stable; many high-tech fields The production and products of other vibration-sensitive precision instruments, such as laser equipment, photoelectric microscopes, semiconductor devices, integrated circuits, microchips and processors, have extremely strict requirements on the working environment; Vehicles, staff, elevators, vacuum pumps, compressors, fans and other wo...

Problems solved by technology

[0003] According to the research data on structural vibration control at home and abroad, the theoretical research of passive control technology is relatively early and sufficient, and the engineering application is also relatively extensive, but it cannot be adjusted in real time according to the actual external excitation changes, and its low-frequency and ultra-low frequency interference control The effect is not good, and sometimes the dynamic response of the controlled structure will be amplified; the active control technology has large output, low energy consumption, and quick response. The basic principle is to automatically adjust the control force output according to the structural dynamic response, and collect the structural response through sensors. Then get the corresponding output control force command through the processor operation
