摘要: 条带悬挂支撑天平是1.2m×1.2m 风洞条带悬挂支撑测试系统中的重要组成部分,为确保天平研制成功,通过有限元分析仿真提出了一种“E”型天平新结构。天平有限元仿真、静态校准、动校和风洞试验结果表明天平结构合理,性能优良。Abstract: The vane cable suspension support balance is important component of the vane cable suspension support system in 1.2m × 1.2m wind tunnel,in order to ensure successful development of balance,a new balance structure as the shape of word “E”is presented by finite element analysis(FEA)simulation.Results of balance FEA simulation,static calibration,dy-namics calibration and wind tunnel test show the balance have reasonable structure and excellent performance.
