Abstract

The invention relates to a miniaturized angle sensitive and control device applied to a liquid-floating inertial instrument, which includes a polyhedron magnetic pole mounting frame, an excitation coil, a permanent magnet, a moving coil frame, a sensor coil and a torquer coil, and the excitation coil and the permanent magnet are installed on the A stator assembly is formed on the polyhedral magnetic pole mounting frame, and a moving coil frame is arranged coaxially outside the polyhedral magnetic pole mounting frame, and sensor coils and torquer coils are arranged on the moving coil frame. The invention describes a miniaturized angle sensitive and control device applied to a liquid-floating inertial instrument. The present invention improves the structure of the sensor and torque device for the liquid-floating inertial instrument to achieve the goal of miniaturization, and can meet the index of the inertial instrument Requirements, suitable for low-precision applications in liquid-floating inertial instruments.

Description

technical field [0001] The invention relates to the technical field of sensors and torque devices for single-degree-of-freedom liquid-floating inertial instruments, in particular to a miniaturized angle-sensitive and control device applied to liquid-floating inertial instruments. Background technique [0002] Liquid-floating inertial devices, such as gyroscopes and accelerometers, are products with mature technology and have many advantages such as high precision and good reliability. They are still widely equipped in active weapons and equipment. Traditional liquid floating gyroscopes and accelerometers are often complex in structure and large in size, which deviates from the very demanding volume requirements of modern weapons and equipment for inertial instruments. [0003] In the liquid floating inertial instrument, the sensor is the key component to measure the sensitive external input of the inertial instrument, and the torque device is used to control or maintain the ...
