摘　　要：针对立式风洞垂直试验段流场性能测试要求,设计基于双塔结构的校测架系统。全闭环交流伺服控制系统使上、下丝杠连接板带动排管架做高精度同步或单步定位控制;配合控制系统实现空间定位,由方向动压组合探头和DSM电子扫描阀组成的测量系统实现了方向场、动压场、轴向静压梯度等参数的校测。结果表明:在v=35 m/s时,各截面合格区域面积均达到75%以上。应用该系统成功完成了立式风洞流场校测任务,测量数据准确,校测结果满足国军标要求。According to the requirements of flow field performance test in the vertical test section of vertical wind tunnel, a calibration frame system based on double-tower structure is designed. The full closed loop AC servo control system makes the upper and lower screw connecting plates drive the rack to do high precision synchronous or single-step positioning control;the space positioning is realized by cooperating with the control system, and the calibration of parameters such as directional field, dynamic pressure field and axial static pressure gradient is realized by the measurement system composed of directional dynamic pressure combination probe and DSM electronic scanning valve.The results show that when v = 35 m/s, the qualified area of each section is more than 75%. The system has successfully completed the task of vertical wind tunnel flow field calibration, the measurement data is accurate, and the calibration results meet the requirements of the national military standard.
