| Summary: | Wind tunnel test is an important part of the development of the aircraft, and the aircraft position and attitude adjustment mechanism is an indispensable part of the test. An adjusting mechanism capable of achieving multi-path angle coupling output is proposed. Firstly, the implementation principle of the mechanism is introduced. The kinematics equation derivation is performed. Combine with Matlab and set the aircraft under two kinds of motion conditions, the drive the displacement and velocity of mechanism are solved, and the spatial motion trajectory of the aircraft is calculated. On this basis, the drive extreme displacement is set. The boundary mapping method is used to analyze the workspace of the mechanism. The results show that the mechanism has a large workspace and could complete the adjustment of a wide range of aircraft path angles within the set of two extreme displacement. As a wind tunnel test adjustment mechanism has application prospects. |
