Integrated electromagnetic energy feedback vibration isolator

Abstract

The invention provides an integrated electromagnetic energy feedback vibration isolator. The integrated electromagnetic energy feedback vibration isolator is characterized by comprising a moving coil type electromagnetic linear actuator based on a Halbach permanent magnet array, a vibration isolator guide rod, an upper end cover, a lower end cover, a sealing cover, an upper lifting lug and a lower lifting lug. A permanent magnet body of the electromagnetic linear actuator is attached to the inner side of an outer magnet yoke, coils are divided into a vibration reduction coil assembly and an energy feedback coil assembly, a coil framework, an inner magnet yoke and a piston rod are connected through bolts, the end covers are arranged at the upper end and the lower end of the outer magnet yoke, and a lubricating piece is arranged in the lower end cover. According to the integrated electromagnetic energy feedback vibration isolator, while active control performance advantages of the electromagnetic energy feedback vibration isolator are fully played, vibration energy is recycled to make up for electric energy consumed by active control, and the problem of contradiction among the structural size, vibration reduction performance and energy consumption of the active vibration isolator is solved. The integrated electromagnetic energy feedback vibration isolator has the advantages of being high in power density, low in energy consumption, high in control precision, modularized in stroke and the like, and the overall performance of the vibration isolator is effectively improved.
