| 为研究模型在大攻角通气条件下的气动特性，研制专用通气测力风洞试验装置，该装置由1台六分量天平、2个波纹管及其他零件组成。波纹管实现模型的通气及气密性需求，天平实现模型的测力需求。采用ANSYS软件模拟分析了天平、波纹管的特性，获得了详细结构以及波纹管对天平干扰的理论结果，通过静态校准分别得到天平、测力装置工作公式，对比结果表明，有限元分析与实测结果一致。利用风洞试验进一步检验该测力装置的测量准确性，结果显示，该测力装置达到设计指标，满足该类型风洞试验需求。 |

| In order to study the aerodynamic characteristics of the model under high angle of attack ventilation, a special ventilation force measurement wind tunnel test device was developed. The device consists of a six component balance, two bellows and other parts. The bellows realize the ventilation and air tightness requirements of the model, and the balance realizes the force measurement requirements of the model. ANSYS software is used to simulate and analyze the characteristics of the balance and bellows. The detailed structure and theoretical results of bellows interference on the balance are obtained. The working formulas of the balance and the force measuring device are obtained by static calibration. The results show that the finite element analysis is consistent with the measured results. The measurement accuracy of the force measuring device is further verified by wind tunnel test. The results show that the force measuring device meets the design requirements and meets the requirements of this type of wind tunnel test. |
