Aircraft attitude-simulating 3-degree-of-freedom electrical turntable

Abstract

The invention relates to an aircraft attitude-simulating 3-degree-of-freedom electrical turntable, belonging to the technical field of simulation. The aircraft attitude-simulating 3-degree-of-freedom electrical turntable is characterized in that: the 3-degree-of-freedom electrical turntable comprises an inner frame, a middle frame, an outer frame and a turntable pedestal, wherein the turntable pedestal is equipped with the outer frame, the outer frame is equipped with the middle frame, and the middle frame is equipped with the inner frame; a rotating shaft of the outer frame is provided with a driving DC torque motor, and the motor is coaxially installed with a coded disc; a shaft of the middle frame is arranged on the outer frame and provided with two parallel driving DC torque motors, and the motors and the coded discs are arranged at both ends; the inner frame is provided with one driving DC torque motor, the coded disc and the motor are coaxially installed, and the shafts of the outer frame, the middle frame and the inner frame are spatially vertical to each other and intersect at one point. The aircraft attitude-simulating 3-degree-of-freedom electrical turntable has the advantages of: simple structure, compact assembly, low cost and good practicability, accurate data, high simulation degree, high precision and good dynamic performance in simulating the aircraft attitude, etc.

Description

technical field [0001] The invention belongs to the technical field of simulation, and in particular relates to a three-degree-of-freedom electric turntable for aircraft attitude simulation. Background technique [0002] At present, the purpose of flight motion and automatic flight control system simulation is to realize flight motion law and flight control method research. The existing flight control system lacks a three-degree-of-freedom electric turntable for aircraft attitude simulation, which has poor stability and inaccurate simulation data. The effect is large, the realism is poor, the distortion is serious, and even the training results are inconsistent with the actual operation of the aircraft due to data distortion, which brings hidden dangers such as flight safety. There is an urgent need for a three-degree-of-freedom electric turntable for aircraft attitude simulation to make up for this technical defect. SUMMARY OF THE INVENTION [0003] The present invention...

[0002] At present, the simulation of flight motion and automatic flight control system is aimed at the realization of flight motion law and flight control method research. The existing flight control system lacks a three-degree-of-freedom electric turntable for aircraft attitude simulation, which has poor stability and inaccurate simulation data, resulting in The effect deviation is large, the sense of reality is poor, and the distortion is serious. Even the training result is inconsistent with the actual operation of the aircraft due to data distortion, which brings hidden dangers such as flight safety.
