摘要
风洞试验中,对模型两侧前沿边条的控制是动态试验一个新的预研方向,在控制系统上做为特种试验研究也是一个全新的方向。本文架构了一套基于X-Y数控平台的边条控制系统,利用数控技术圆弧插补原理对边条正弦往复运动进行控制。通过仿真调试,对系统控制参数进行了修正,减小了跟随误差,使边条实际运动轨迹最大限度逼近指令轨迹;通过风洞试验应用验证了这套系统的可行性与高精度。
In wind-tunnel test, it is a new trend to control the leading edge of aircraft model for dynamic test, and also for special experimental research. Based on the principle of the CNC servo for X-Y table circular interpolation, a new leading edge controlling system is proposed. The control parameter of the system is modified after simulation and analysis, so that the error is reduced and the practical motion trajectory of leading edge maxi- mumly approaches the instruction trajectory. The result of wind tunnel test shows that this system is feasible and has high accuracy.
