Problems solved by technology

The multi-cylinder parallel motion mechanism is bulky, the two-axis motion is coupled with each other, the control is complex, and the motion space is limited, which restricts the attitude control performance of the motion simulator
Redundant parallel mechanism branch chain drive redundancy, the number of mechanism drives is greater than the number of degrees of freedom of the mechanism, and there is a strong coupling phenomenon between the branch chains when the mechanism is moving, which brings great trouble to the motion control of the mechanism. Once the movement is uncoordinated, it will cause The movement of the mechanism is faulty. Secondly, when solving the kinematics and dynamics of the mechanism, the equation has multiple solutions or no solution, which makes the dynamic control of the mechanism very difficult.

Abstract

The invention relates to a fully decoupled two-axis swing mechanism with symmetrical arrangement. The mechanism includes a base, a three-way cross-axis mechanism, a swing platform and a linear drive device; Axis swing action, and the angular velocity and angular displacement of the mechanism are controlled by controlling the speed and displacement of the drive rod of the linear drive device; the mechanism realizes the full decoupling of the two-axis swing motion through its own structure, and can complete front and rear pitching and left and right rolling actions , and do not interfere with each other, it can be widely used in aircraft and ship simulators for motion simulation. In addition, the mechanism has the characteristics of compact space layout, light weight, fast dynamic response and simple motion control.

Description

technical field [0001] The invention relates to the technical field of multi-degree-of-freedom rotating mechanisms, in particular to a fully decoupled two-axis swing mechanism with symmetrical arrangement. Background technique [0002] At present, with the rapid development of aircraft and ship simulation technology, the two-axis swing mechanism is widely used in aircraft and ship simulators to realize the forward and backward pitch and left and right tilt of the simulator, which has broad application prospects. [0003] The existing two-axis swing mechanism mostly adopts the form of a multi-cylinder parallel kinematic mechanism or a redundant parallel mechanism. The multi-cylinder parallel motion mechanism is bulky, the two-axis motion is coupled with each other, the control is complex, and the motion space is limited, which restricts the attitude control performance of the motion simulator. Redundant parallel mechanism branch chain drive redundancy, the number of mechanis...
