Abstract

The invention provides a three-degree-of-freedom motion simulator. The simulator comprises a fixed platform, a moving platform, three parallel motion branches and a linear driving mechanism corresponding to the three motion branches; the three motion branches and identical in structure, a first end of each motion branch is connected with the fixed platform through a first Hook joint, and a secondend is connected with the moving platform through a second Hooke joint; each motion branch comprises comprises a first connecting rod, a second connecting rod and a first revolute pair; a first end ofthe linear driving mechanism used for driving the motion branches is rotationally connected with the first connecting rod, a second end of the linear driving mechanism is rotationally connected withthe second connecting rod and used for driving the second connecting rod to swing around the first connecting rod; the first Hooke joints and the second Hooke joints of the motion branches are symmetrical relative to the first plane which is the plane passing through the middle points of the first rotating pairs of the motion branches. The three-degree-of-freedom motion simulator is good in motioncontrol performance and small in occupied space.

Description

technical field [0001] The present application relates to the technical field of motion simulators, in particular to a three-degree-of-freedom motion simulation device. Background technique [0002] With the continuous popularization of VR equipment, not only the national level pays attention to the development of virtual reality supporting technology, but also the movement simulation of transportation equipment, entertainment simulators, 4D theaters, theme parks and medical auxiliary equipment for new low-cost motion simulation with less degrees of freedom. Devices are also generating huge demand. [0003] The motion simulator receives the motion signal given by the computer by driving the controller, matches it with the motion in the virtual environment and simulates it in real time, so that the users on the motion platform feel a very strong sense of immersion. Most motion simulators are six-degree-of-freedom motion simulators, which are difficult to miniaturize and are ...
