High-low temperature and high-frequency angular vibration device based on hydrostatic bearing system

A high-low temperature and high-frequency angular vibration device based on a hydrostatic bearing system, comprising:

• an angular vibration table assembly;
• a temperature-controllable chamber;
• and
• a control system;
• wherein the angular vibration table assembly comprises a base, a hydrostatic bearing, a torque motor, an adapter assembly, an encoder, a conductive slip ring, a thermal-insulating shaft and a worktable;
• the base is arranged at a bottom of the angular vibration table assembly;
• the torque motor comprises a stator and a rotor;
• the stator is arranged inside the base, and is fixedly connected to the base;
• the torque motor is internally provided with a motor shaft;
• and the rotor is connected to the motor shaft;
• the hydrostatic bearing is arranged at an outer periphery of the base;
• a top of the motor shaft is fixedly connected to the hydrostatic bearing through the adapter assembly;
• and a bottom of the motor shaft is provided with the encoder;
• the conductive slip ring is arranged on the encoder;
• the worktable is arranged inside the temperature-controllable chamber;
• and a top of the adapter assembly is connected to the worktable through the thermal-insulating shaft;
• and
• the control system is configured to control a temperature of the temperature-controllable chamber, and an angular frequency, an angular rate and an angular position of the angular vibration table assembly.
