Problems solved by technology

The serial motion simulator has a large rotation space but has the problem of poor stiffness. The parallel motion simulator has higher stiffness than the serial motion simulator. However, due to the influence of singularity and rod interference, it is difficult for the current parallel motion simulator to simulate large Angle rotation state

Abstract

The invention discloses a redundant-drive six-freedom-degree motion simulator, relating to a motion simulator, which is suitable for simulating the real motion posture of equipment and solves the problems of poor rigidity and small turn angle of the simulator. The simulator comprises a rack, linear moving assemblies, a combined motion assembly, connecting rod assemblies, a vertical rotation assembly and a cabin assembly. One ends of the first, second, third and fourth connecting rod assemblies are fixedly connected with sliders of the first, second, third and fourth linear moving assemblies, and the other ends of the first, second, third and fourth connecting rod assemblies are connected with the first and second horizontal rotation joints and the first and second horizontal fit joints in the cabin assembly through universal joints, so that one hooke joint is formed; and the combined moving assembly is fixedly connected with sliders in the fifth and sixth linear moving assemblies, and the vertical rotation assembly with a fixed upper end is connected with a U-shaped joint in the cabin assembly through a universal joint, so that the other hooke joint is constituted. The sliders move linearly along a guide rail to drive connecting rods and a vertical guide rail frame to move so as to realize the motion input to a cabin, and thus, the posture switching among pitching, turning, translating and the like is realized.

Description

technical field [0001] The invention relates to a redundantly driven six-degree-of-freedom motion simulator, which is suitable for simulating the motion posture of real equipment and providing a dynamic feeling for the operator. Background technique [0002] The motion simulator is a semi-physical simulation device that simulates the motion posture of the real device and provides the operator with a dynamic feeling. In recent years, with the development of computer technology and system simulation technology, motion simulators have made great progress in technology and are widely used in various industries, such as military, transportation, energy, education and commercial games. Sports simulators can effectively improve the comfort and safety of training, effectively improve training efficiency, and shorten the training cycle. The development and research of the corresponding motion simulator is conducive to the designer to find design defects and errors, and reduce the co...
