Abstract

The invention belongs to the field of pneumatic technology, relates to a gas-driven motion simulator, in particular to a three freedom degree motion simulator of a pneumatic hybrid mechanism; the invention is a novel three freedom degree motion simulator of the pneumatic hybrid mechanism, which is driven by an air cylinder and a pneumatic artificial muscle in a mixing mode to realize combination of a parallel mechanism and a serial mechanism; wherein the parallel mechanism consists of a first angle sensor, a second angle sensor, a crossing shaft, a hooker hinge, a pneumatic artificial muscle, an upper platform and a lower platform, and is used for realizing the two rotational freedom degree; the serial mechanism consists of the air cylinder, a base, a linear bearing, a guiding rail and a flange, and is used for realizing the freedom degree of up-and-down movement; the serial mechanism is connected with the lower platform of the parallel mechanism by threads; and servocontrol of the three freedom degree motion simulator is realized by a pneumatic control mechanism. The invention has the advantages of simple structure, mutual independence of three freedom degree, good controllability, fast response of pneumatic control and good softness of pneumatic artificial muscle.

Description

technical field [0001] The invention relates to a gas-driven motion simulator, in particular to a three-degree-of-freedom motion simulator of a pneumatic hybrid mechanism, which is a new type of pneumatic hybrid that uses a hybrid drive of a cylinder and a pneumatic artificial muscle to realize both a parallel and a series mechanism. A three-degree-of-freedom motion simulator for mechanisms. technical background [0002] The parallel mechanism has the characteristics of high rigidity, strong bearing capacity, small self-weight-to-load ratio, fast response speed, and good dynamic performance. It is especially suitable for applications with small working space and large load. At present, the vast majority of parallel systems at home and abroad are driven by motors or hydraulic pressure. For the motor system, the motor is easy to start, and can be designed to have a low moment of inertia, and the acceleration and deceleration characteristics are good, but to obtain a large pow...
