风洞试验是飞行器研制的重要环节,飞行器位姿调节机构更是试验必不可少的部分。提出一种能实现多航向角耦合输出的调节机构。首先对该机构的实现原理进行了介绍,并进行了运动学方程推导;结合Matlab并设定飞行器在两种运动情况下,求解驱动位移、速度输入情况,同时计算出飞行器空间运动轨迹;在此基础上,设定驱动位移极值,采用边界映射的方法,对机构的工作空间进行分析。结果表明,该机构在设定的两组极值范围内具由较大工作空间,可完成飞行器大范围航向角的调节;作为风洞试验调节机构具有一定应用前景。
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.
