The invention relates to a
simulation device, in particular to a three-
dimensional simulation motion device. The three-
dimensional simulation motion device comprises a fixed base, a plurality of motion supporting bodies, a three-dimensional rotation device, an outer rotation supporting body and an inner motion platform, wherein the motion supporting bodies can be vertically lifted, the three-dimensional rotation device is used for achieving three-dimensional rotation motion, the outer rotation supporting body is used for supporting the three-dimensional rotation device, and the inner motion platform is arranged in the three-dimensional rotation device and used for achieving longitudinal rectilinear motion and transverse rectilinear motion. The motion supporting bodies are evenly arranged, the bottom ends of the motion supporting bodies are all fixed on the fixed base, the outer rotation supporting body is a horizontally-arranged annular structure body, and the outer edge of the outer rotation supporting body is connected with the top ends of the motion supporting bodies. The three-
dimensional simulation motion device is a
simulation motion platform formed by the three-dimensional rotation device and a rectilinear motion device in a combined mode, various
spatial motion postures can be completely simulated, and the three-dimensional
simulation motion device can be applied to various simulated training devices such as flight simulators, driving simulators and
recreation equipment, and various actual requirements of various kinds of simulated training can be met.
