摘要
为保证支撑装置在实现迎角α和侧滑角β精确定位过程中,按照要求的角速度匀速转动,并保证在转动过程中模型中心不偏离风洞轴线,对迎角α机构、侧滑角β机构、Y向升降机构速度和位置运动关系进行数学分析。进行复杂运动的详细解算,对多轴联动速度和位置控制方法进行深入研究,采用控制虚拟主轴。结果表明:α、β、y机构位置随动的方法,实现了迎角α、侧滑角β和Y向机构的高精度速度和位置控制,精度均控制在0.02°和2 mm以内,满足设计要求。
In order to ensure that the support device rotates at the required angular velocity in the process of realizing the precise positioning of the angle of attack α and the angle of sideslip β,and to ensure that the center of the model does not deviate from the axis of the wind tunnel in the process of rotation,the mathematical analysis of the speed and position motion relationship of the angle of attackαmechanism,the angle of sideslipβmechanism and the Y-direction lifting mechanism is carried out.The complex motion is calculated in detail,and the multi-axis linkage speed and position control method is studied in depth.The virtual spindle is controlled.The results show that the method ofα,β,Y mechanism position follow-up realizes the high-precision speed and position control of angle of attackα,sideslip angleβand Y mechanism,and the accuracy is controlled within 0.02°and 2 mm.Meet the design requirements.
