The invention relates to the technical field of aircraft rod piece tests, in particular to an aircraft rod piece calibration test restraining device and method.The device comprises a test bed, a first fixing base, a second fixing base and a third fixing base are arranged on the test bed, the first fixing base is used for being connected with a test piece, and the second fixing base is used for being connected with a third fixing base; a limiting sleeve is arranged on the second fixing seat, a hydraulic actuator is connected to the third fixing seat, a connecting rod capable of moving in the axis direction of the limiting sleeve is arranged in the limiting sleeve, one end of the connecting rod is used for being connected with a test piece, and the other end of the connecting rod is used for being connected with the telescopic end of the hydraulic actuator. Due to the limiting effect of the limiting sleeve on the connecting rod, the coaxiality of the test piece and the hydraulic actuator is ensured, the deviation of the vertical test table board in the load transmission process is weakened, and the accuracy of a test result is improved.

    本发明涉及飞机杆件试验技术领域,具体涉及一种飞机杆件标定试验约束装置及方法,其中装置包括试验台,所述试验台上排列设置有第一固定座、第二固定座和第三固定座,所述第一固定座用于连接试验件,所述第二固定座上设有限位套筒,所述第三固定座上连有液压作动器,所述限位套筒中设有可沿所述限位套筒轴线方向移动的连接杆,所述连接杆一端用于与试验件连接,另一端用于与液压作动器伸缩端连接。由于限位套筒对连接杆的限位作用,确保试验件和液压作动器的同轴度,减弱载荷传递过程中垂直试验台面的偏移,提升试验结果的准确性。
