Problems solved by technology

However, whether it is a Stewart six-degree-of-freedom flight simulator motion platform or a low-degree-of-freedom flight simulator motion platform, most flight simulator motion platforms are difficult to achieve large-inclination roll motion, especially 360-degree roll motion

Embodiment 1

[0012] Such as figure 1 As shown, the four-degree-of-freedom hybrid flight simulator motion platform that can realize 360-degree rolling motion provided by this embodiment includes a base 1, a connecting piece 9, a rotating platform 2, a circular guide rail 3, a vertical guide rail 7, and three sliders 6. Three connecting rods 5, three spherical pairs 4 and a moving platform 8; the base 1 is set horizontally; the lower end of the connecting piece 9 is fixedly connected to the center of the surface of the base 1; the center of the bottom surface of the rotating platform 2 and the upper end of the connecting piece 9 pass through The active rotary pair is connected; the ring guide rail 3 and the vertical guide rail 7 are vertically fixed on the surface of the rotating platform 2 at a distance, and the vertical guide rail 7 is aligned with the vertical bisector of the ring guide rail 3; the two sliders 6 are respectively moved by a The pair is connected with the inner circumferent...

Embodiment 2

[0015] Such as figure 1 As shown, the four-degree-of-freedom hybrid flight simulator motion platform that can realize 360-degree rolling motion provided by this embodiment is different from the flight simulator motion platform provided by Embodiment 1 in that the first vertically arranged on the surface of the rotating platform 2 is used. Two annular guide rails 10 replace vertical guide rail 7, and the setting direction of second annular guide rail 10 and annular guide rail 3 is perpendicular, and second annular guide rail 10 is connected with annular guide rail 3 simultaneously, all the other structures are identical.

[0016] When the four-degree-of-freedom hybrid flight simulator motion platform that can realize 360-degree rolling motion provided by the present invention is in use, the pilot first sits on the moving platform 8 and fixes it. The way the guide rail 7 or the second circular guide rail 10 moves enables the moving platform 5 to realize 360-degree rolling motion...

Abstract

The invention provides a four-degree-of-freedom series-parallel flight simulator motion platform capable of realizing the 360-degree rolling movement. The motion platform comprises a base, a connecting piece, a rotating platform, an annular guide rail, a vertical guide rail, three sliding blocks, three connecting rods, three spherical pairs and a movable platform. A three-degree-of-freedom parallel mechanism is connected in series with the base via the connecting piece. The three-degree-of-freedom parallel mechanism is composed of a rotating platform, the movable platform and three PRS driving branches connected between the rotating platform and the movable platform. The movement locus of each driving prismatic pair in at least two out of the three PRS driving branches is circular, so that the 360-degree rolling movement of the movable platform can be realized. Meanwhile, since the motion platform is provided with relatively fewer branches, the motion platform is simple in structure and easy to control. During the driving simulation of the flight, the motion platform can be applied to the flight training process with specific requirements, such as the aerobatic flight show and the like. Therefore, the four-degree-of-freedom series-parallel flight simulator motion platform has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of hybrid mechanisms, in particular to a four-degree-of-freedom flight simulator motion platform composed of a parallel mechanism consisting of two degrees of freedom of rotation and one degree of freedom of movement, and a mechanism of one degree of freedom of rotation in series. Background technique [0002] The aircraft simulator motion platform can provide the instantaneous overload dynamics felt by the pilot during the aircraft movement, the continuous sense of the gravity component and part of the jitter information, so that the pilot feels similar to the flight on the ground as the aircraft in the air. The motion platform of a full-mission flight simulator is usually driven by a Stewart six-degree-of-freedom motion platform, but the non-linear, strongly coupled, variable-parameter Stewart six-degree-of-freedom drive platform is expensive and complex in structure. In recent years, the research on the g...
