Problems solved by technology
The motion simulator in series form has a large working stroke and good flexibility, but it has disadvantages such as poor rigidity of the mechanism and large motion inertia.
In comparison, the parallel motion simulator has the advantages of compact structure, high rigidity, small motion inertia, and fast dynamic response, but there are also disadvantages such as small working stroke, singular phenomena in some cases, and difficulty in solving positive kinematics.

The invention discloses a six-degree-of-freedom motion simulator with large translation stroke and high response speed, belonging to the field of mechanics and motion simulators. The motion simulator is composed of a parallel four-degree-of-freedom motion module and a parallel two-degree-of-freedom motion module in series, that is, the static platform of the two-degree-of-freedom motion module is fixed on the four-degree-of-freedom motion module in a specific relative position. On the moving platform, the static platform of the four-degree-of-freedom module is used as the static platform of the motion simulator, and the dynamic platform of the two-degree-of-freedom module is used as the dynamic platform of the motion simulator. The two driving devices of the degree of freedom module realize the six-degree-of-freedom movement of the dynamic platform of the motion simulation relative to its static platform. The motion inertia of the moving platform of the invention is small, the control difficulty is reduced, and the dynamic response is fast.
Description
