| 摘 要： | 为满足某飞机部件高速测力试验的需要,研制6台部件测力天平来测量飞机不同部件(机翼、平尾、垂尾、短舱、短舱+挂架、翼尖小翼)所受的气动载荷,天平设计载荷极不匹配,且模型空间有严格的限制.设计时,主机测力天平采用后腹支撑,安装在机身构造线的下方,为部件天平的安装提供了可能,同时针对不同的天平采用了不同的结构形式:机翼天平采用正八边形结构,垂尾天平采用三片梁结构,平尾天平、短舱、短舱+挂架采用矩形梁结构,翼尖小翼天平采用"Z"字形结构,既满足了天平的测量需要,又确保了天平在模型中的安装位置和试验的足够间隙.部件天平的成功研制,及时为型号研制提供了可靠的试验数据.

| Abstract: | The component forcing balances were developed for measuring aerodynamic loads on the different components of airplane.The design loads of these component forcing balances did not match in all components,and the sizes were rigorously confined by models' space.In balance design,the support behind the airplane's abdomen was used for the airplane balance,and the balance was fixed under the airframe's horizontal line,which provide the feasibility for the component balance installation.The different structures in different component balances were adopted to meet the need of balance measurement and ensured the balances installing position in the model and to meet the need for interval in test.The structure of equilateral octagon was used for the wing balance,the three sheet girder was used for the vertical wing balance,the rectangle girder was used for the horizontal wing balance,nacelle balance,nacelle and it's bracket balance,the "Z"structure was used for the little wing at the tip of the wing balance.The successful development of these component balances provides the reliable testing data for the models' development. |
