Flight simulator 3DOF cockpit

Abstract

The invention discloses a flight simulator 3DOF cockpit which comprises an inner cabin and an outer cabin, the outer cabin is fixed, and the inner cabin is provided with a control device; the 3DOF cockpit further comprises a first driving motor, a second driving motor and a third driving motor; the outer surface of the inner cabin and the inner surface of the outer cabin are concentric spherical;the three groups of universal gears are mounted in the inner cabin; the connecting lines of the centers of the three groups of universal gears and the sphere center of the outer surface of the inner cabin are three mutually orthogonal axes; the inner surface of the outer cabin is rough, driven wheels of the three sets of universal gears are coupled with the inner surface of the outer cabin, and the inner cabin is supported in the outer cabin; and the three groups of universal gears are independently driven by a driving motor respectively. The inner cabin is supported in the outer cabin throughcoupling of the three groups of universal gears and the rough inner surface of the outer cabin. And under the action of the driving motor, the universal gears rotate on the inner surface of the outercabin and drive the inner cabin to rotate. During rotation, the rotation in three axial directions is completely independent, and the multi-angle and multi-attitude flight of the aircraft in space can be simulated.

Description

technical field [0001] The invention relates to the technical field of flight simulators, in particular to a flight simulator 3DOF cockpit structure. Background technique [0002] The structure of the existing flight simulator, disclosed as known CN201210297245.6: multi-axis flight simulator, including the outer ring, the center ring, the inner ring of the nest connection, the outer ring is fixedly arranged on the base, the outer ring, the center The ring and the inner ring are respectively driven by independent servo motors, and the center ring connects to the simulator cockpit inward. The three-dimensional rotation is realized by adopting the connection mode of three groups of rotation axes orthogonally nested. This structure is similar to the structure of the gyroscope. The schematic diagram of the structure is as follows: figure 1 shown. [0003] Existing flight simulators have the following problems: for the controlled object in the innermost cockpit, its rotation axi...

AI Technical Summary

Problems solved by technology

[0003] Existing flight simulators have the following problems: for the controlled object in the innermost cockpit, its rotation axis is an absolute stationary coordinate system, rather than the controlled object's own coordinate system, which is determined by its structural complexity and principle It cannot use the built-in coordinate system

This is a flaw caused by the structural design of existing flight simulators

[0005] Therefore, the prior art cannot well solve the rotation control problem of the three degrees of freedom, and there is still a long way to go before fully simulating the flight attitude of the aircraft.
