Six-degree-of-freedom parallel dynamic platform

Abstract

The invention relates to a six-degree-of-freedom parallel dynamic platform. The six-degree-of-freedom parallel dynamic platform comprises a display device (1), an operation platform (5), an upper platform (3), an execution mechanism (32), a lower platform (21) and a control system (33); the display device (1) and the operation platform (5) are respectively arranged on the upper platform (3); two ends of the execution mechanism (32) are respectively fixed on the upper platform (3) and the lower platform (21); and the control system (33) is located in the lower platform (21). With the six-degree-of-freedom parallel dynamic platform of the invention adopted, defects in the prior art can be eliminated, and simulation experience of an operator and the reliability of the mechanism can be enhanced, and up-and-down, left-and-right and front-and-back translation and rotation can be realized. The six-degree-of-freedom parallel dynamic platform has the advantages of stable movement and convenient operation, and can bearing a large load.

Description

technical field [0001] The invention is a parallel dynamic platform with six degrees of freedom, which can realize translation and rotation of up and down, left and right, front and back. The utility model has the advantages of large load bearing, stable movement and convenient operation, and belongs to the technical fields of automobile simulation, motion simulation and scientific experiment. Background technique [0002] Among the traditional dynamic platforms, there are dynamic platforms with two degrees of freedom, three degrees of freedom and six degrees of freedom. In two-degree-of-freedom and three-degree-of-freedom, due to the lack of degrees of freedom, the user's immersion, interactivity and multi-perception are poor, which cannot be compared with the six-degree-of-freedom dynamic platform. At present, most of the six-degree-of-freedom dynamic platforms on the market are driven by hydraulic pressure. The cost of the hydraulic system is high, it is inconvenient to ...

In two degrees of freedom and three degrees of freedom, due to the lack of degrees of freedom, the user's immersion, interactivity and multi-perception are poor, which cannot be compared with the six degrees of freedom dynamic platform

At present, most of the six-degree-of-freedom dynamic platforms on the market are driven by hydraulic pressure. The cost of the hydraulic system is high, it is inconvenient to maintain, and it is easy to pollute the environment; the connection between the actuator and the upper and lower platforms is connected by a Hookee hinge. The impact force is relatively large; the upper platform connected to the Hooke hinge is a plane, which raises the center of gravity of the motion mechanism and limits the speed and acceleration of the mechanism movement; the positions of the steering wheel and brake pedal of the traditional dynamic platform are mostly fixed. Some only have manual gear, which cannot adapt to people with different body types and different operating habits.

Therefore, although the traditional six-degree-of-freedom dynamic platform has improved immersion, interactivity and multi-sensory performance compared with two-degree-of-freedom and three-degree-of-freedom platforms, it is still limited.
