【摘要】 风洞试验是飞行器研制发展过程中不可缺少的环节，双转轴支撑装置是应用于风洞采集飞行器实验数据的关键设备。根据双转轴支撑装置的结构特点，建立风洞试验用双转轴支撑装置运动控制的数学模型，得到机构角和飞行器模型角的运动学解析函数。在Matlab平台上采用数据拟合的方法得到尾轴和滚转角的误差补偿函数，据此设计尾轴和滚转角的误差补偿方案。更多还原

【Abstract】 Wind tunnel test is an indispensable link in the process of aircraft research and development, and the double rotating shaft support device is the key equipment used in wind tunnel to collect aircraft experimental data. This paper establishes the mathematical model of the motion control of the double-rotating shaft support device used in wind tunnel test according to the structural characteristics of the double-rotating shaft support device, and obtains the kinematic analytic functions of the mechanism angle and the aircraft model angle. The error compensation function of stern shaft and roll angle is obtained by data fitting method on Matlab platform, according to which, the error compensation scheme of stern shaft and roll angle is designed.更多还原
