The invention relates to an aircraft curved surface tension and compression loading clamp in an aircraft structural strength static/fatigue test, in particular to an aircraft curved surface tension and compression bidirectional loading clamp. An airplane curved surface tension and compression loading clamp is characterized in that the connection parts of the tension and compression loading clamp and an airplane curved surface are in hard connection, and the airplane curved surface tension and compression loading clamp comprises a curved surface tension and compression loading block assembly and a loading lever assembly; the curved surface tension-compression loading block assembly comprises a plurality of curved surface tension-compression loading blocks, and each curved surface tension-compression loading block comprises an aircraft appearance fitting plate and a loading lug; the loading lever assembly comprises a loading lever A, a loading lever B and a loading lever C, the two ends of the loading lever A are rotatably connected with the adjacent curved surface tension and compression loading blocks respectively, the two ends of the loading lever B are rotatably connected with the adjacent loading lever A respectively, and the two ends of the loading lever C are rotatably connected with the adjacent loading lever B. The method has the following advantages: 1, the loading response speed is high, and the fatigue test period is shortened; 2, the load transmission is more real;

    本发明涉及一种在飞机结构强度静力/疲劳试验中飞机曲面拉压加载夹具,尤其涉及一种飞机曲面拉压双向加载夹具。一种飞机曲面拉压加载夹具,所述拉压加载夹具与飞机曲面的连接部位均为硬式连接,其包括曲面拉压加载块组件、加载杠杆组件;曲面拉压加载块组件包括若干曲面拉压加载块,曲面拉压加载块包括飞机外形贴合板、加载耳;加载杠杆组件包括加载杠杆A、加载杠杆B和加载杠杆C,加载杠杆A的两端分别与相邻曲面拉压加载块可转动连接,加载杠杆B的两端分别与相邻加载杠杆A可转动连接,加载杠杆C的两端分别与相邻加载杠杆B可转动连接。本发明具有如下优点:1、加载响应速度快,缩短了疲劳试验的周期;2、载荷传递更加真实。
