[0003] The gyroscope that provides satellite micro-angular vibration information must have the characteristics of large bandwidth (close to 1KHz), small size, light weight, long life, and shock resistance. At present, neither traditional mechanical gyroscopes, fiber optic gyroscopes, nor MEMS gyroscopes can combine these characteristics. characteristic

The invention relates to a magnetic-fluid gyroscope. An inwardly-concave stud bolt hole is formed at the outer bottom of a metal shell, and a permanent magnet, a sealing sleeve, a core column, a pressing sleeve and a threaded gland are arranged inside the metal shell, wherein the bottom of the permanent magnet is connected with the inner bottom surface of the metal shell, the sealing sleeve is arranged on the permanent magnet and wraps the outer periphery edge of the permanent magnet, a seal ring is arranged at the outer periphery of the sealing sleeve, the bottom end surface of the core column is connected with the center part of the upper end surface of the sealing sleeve, an inner electrode hole sinking inwardly in the axial direction is formed on the upper end surface of the core column, a run-through hole is formed in the pressing sleeve in the axial direction, the pressing sleeve is sleeved at the periphery of the core column through the run-through hole, a fluid flow passage is formed between the bottom end surface of the pressing sleeve and the upper end surface of the sealing sleeve, magnetic fluid is arranged in the fluid flow passage, the threaded gland is embedded into a space formed by the pressing sleeve and the inner periphery edge of the metal shell and is in threaded connection with the inner periphery edge of the metal shell, and two outer electrode holes are symmetrically formed in the threaded gland. The magnetic-fluid gyroscope has the characteristics of high reliability, high intensity and long life, and can stably work in a severe environment such as high impact strength.
Description
technical field [0001] The invention relates to a spinning top. In particular, it relates to a magnetic fluid gyro which is insensitive to vibration acceleration and quadrature axis angular velocity based on a magnetic fluid angular vibration sensor. Background technique [0002] At present, major aerospace countries are competing to develop satellite platforms and application technologies such as high-resolution earth observation and high-precision pointing. Satellite micro-angle vibration measurement and control is the premise and basis for realizing high-precision attitude pointing of payloads such as satellite platforms and remote sensing systems. [0003] The gyroscope that provides satellite micro-angular vibration information must have the characteristics of large bandwidth (close to 1KHz), small size, light weight, long life, and shock resistance. At present, neither traditional mechanical gyroscopes, fiber optic gyroscopes, nor MEMS gyroscopes can combine these cha...
