Active and passive integrated four-feet converged type vibration isolator

Abstract

The invention discloses an active and passive integrated four-feet converged type vibration isolator which comprises an upper connection plate (1), inclined micro-vibration control units (2), a thirdslotted disk spring (4), a lower connection plate (5) and a slotted cylindrical spring (6); one end of the slotted cylindrical spring (6) is connected with the third slotted disk spring (4); the otherend of the slotted cylindrical spring (6) is fixed to the middle part of the lower connection plate (5); the third slotted disk spring (4) is fixed to the middle part of the upper connection plate (1); the inclined micro-vibration control units (2) are uniformly distributed around a center shaft of the slotted cylindrical spring (6) in the circumferential direction of the upper connection plate (1), and are obliquely mounted; one ends of the inclined micro-vibration control units (2) are connected with the upper connection plate (1); and the other ends of the inclined micro-vibration controlunits (2) are connected with the lower connection plate (5). With the adoption of an active and passive integrated structure, wide frequency band micro-vibration control can be realized, the vibrationisolation efficiency of the vibration isolator and the adaptability of the vibration isolator to a complex environment and a changing object are improved.

Description

technical field [0001] The invention relates to a micro-vibration controller. Background technique [0002] With the development of science and technology, the accuracy and resolution of equipment and loads are getting higher and higher, and the stability requirements of the working platform where they are located are also getting higher and higher. The micro-vibration of the environment exists widely for a long time. Inevitably, it will inevitably have an adverse effect on the stability of the platform, and further affect the full performance of the sensors and other equipment. Therefore, a stable working platform becomes a prerequisite for the normal operation of high-performance sensors and other equipment, and micro-vibration control is the key to improving the performance of the platform. effective way to stabilize. [0003] Stabilizing the platform is mainly achieved from two aspects: 1) reduce the disturbance of the platform by other vibration source equipment such a...
