An unobstructed three-axis direct-drive turntable

Abstract

The invention aims at providing a shielding-free triaxial direct-drive rotary table which comprises a base, an orientation frame, a transverse roll frame, a middle frame, an orientation motor, a transverse roll motor and a pitching motor. A stator of the orientation motor is connected with the base, a rotor of the orientation motor is connected with the orientation frame, an orientation shaft system is formed, a stator of the pitching motor is fixed on the orientation frame, a rotor of the pitching motor is connected with the middle frame and a pitching shaft to form a pitching rotary shaft, the pitching shaft is arranged on the orientation frame in a supported mode through a pitching bearing, a stator of the transverse roll motor is connected with the middle frame, a rotor of the transverse roll motor is connected with the transverse roll frame and the transverse roll shaft to form a transverse roll rotary shaft, the transverse roll shaft is arranged on the middle frame in a supported mode through a transverse roll bearing, the transverse roll frame and the orientation frame are both located outside the middle frame, the transverse roll motor is located inside the middle frame, the transverse roll frame is of a U-shaped structure, and an object carrying support is fixed to the transverse roll frame. According to the shielding-free triaxial direct-drive rotary table, when orientation, pitching and transverse rolling are carried out on the three rotary shafts, the carried object is completely located outside a rotary table structure, and the shielding-free triaxial direct-drive rotary table is suitable for carrying out optical testing and simulation on the carried object.

Description

technical field [0001] The invention relates to a simulation device, specifically a three-axis turntable. Background technique [0002] The three-axis turntable is the key equipment for aircraft and ground hardware-in-the-loop simulation. It can simulate the motion of the aircraft in space, such as rolling, pitching, and rolling, and is widely used in the field of aerospace construction. In addition, the three-axis turntable also plays an important role in the static and dynamic testing of the system. [0003] With the development of science and technology, the application scope of the three-axis test turntable is continuously expanding, and the types of loads are correspondingly increased, which also puts forward higher requirements for the turntable. The structural form of the three-axis turntable directly affects performance indicators such as rotation accuracy. Especially in a test system where an optical instrument is used to measure a target on a three-axis turntable...

AI Technical Summary

Problems solved by technology

However, due to structural constraints, the general three-axis turntable will block the measurement target on the load when performing three-axis rotation in azimuth, pitch, and roll, and cannot complete the tasks of measurement and simulation in all directions.
