摘要:
为了研究非对称大膨胀比喷管试验台的喷管气动性能,准确地测量矢量喷管的六分量 气动力,该文依据喷管试验台的测试要求,提出一种新颖的基于T 型梁S 弯变形的框架式整体 六分量天平。通过分析天平的各元微应变与安装结构,设计并制造出天平,依据静态标定获得 天平的工作系数矩阵。最后,用有限元方法验证设计结果。研究表明: 天平的结构简单,精、准 度高,满足试验台的六分量力测量要求。
Abstract:
To study the dynamic performance of a big expansion ratio nozzle with asymmetric structure, a nd measure the six-component dynamic force accurately for the thrust vectoring,a novel integrated six-component force balance is introduced in the paper based on S-bend deformation of Tbeams. By analyzing the measuring microstrain and the assembled structure of the test-bed, the balance is designed and fabricated. The static calibration is employed to obtain the matrix of working coefficients for the balance and the finite element method is included to demonstrate the presented design method. Research result shows that the presented balance has a simple structure and high precision and accuracy,which can meet the demands of a six-component force measurement for the big expansion ratio nozzle test-beds.
