Abstract

The invention provides a novel high-precision hybrid vibration isolation device. The novel high-precision hybrid vibration isolation device comprises an assembly plate, an intermediate separation plate, a bottom plate, an air spring and magnetorheological dampers, wherein the assembly plate and the intermediate separation plate are connected through the magnetorheological dampers; the intermediate separation plate is fixedly connected with the air spring through bolts; and the bottom plate is fixedly connected with the air spring. The magnetorheological dampers are used for isolating low-frequency vibration signals coming from the ground; and since practical ground signal sources can be transferred along multi-dimensional directions, the four magnetorheological dampers have vibration isolation capability of six DOF (Degree of Freedom) directions. The air spring and the magnetorheological dampers are reasonably connected with the intermediate separation plate, so that high-precision active and passive hybrid vibration isolation capability can be realized. According to the novel high-precision hybrid vibration isolation device disclosed by the invention, a stackable structure is adopted, so that the structure is compact; the vibration isolation capability of multi-DOF can be realized, so that the novel high-precision hybrid vibration isolation device has the advantages of high practicability, high reliability and the like; and an advanced vibration isolation means is provided for a high-precision equipment platform.
