The invention relates to a pure bending moment loading strength test device for a wing box section, which is used for carrying out a pure bending moment loading strength test on the wing box section, and a first actuating cylinder and a second actuating cylinder can pass through a first loading box section, a first loading adapter plate, a first end adapter plate and a first end steel plate; the first loading box section, the second loading adapter plate, the second end adapter plate and the second end steel plate are used for applying a load to the wing box section, and in the process, a first end base plate connected to the bottom side of the first loading box section and a first end convex part supported by a first end bracket can rotate and translate in the spanwise direction; and a second end convex hinge connected with the second loading box section and a second end concave hinge supported by the second end bracket can only start to rotate and cannot generate spanwise translation, so that the pure bending moment load can be stably applied to the wing box section, and in addition, the test can be smoothly completed when the test load is relatively large.
本申请涉及一种机翼盒段纯弯矩受载强度试验装置,利用其进行机翼盒段纯弯矩受载强度试验,可以第一作动筒、第二作动筒通过第一加载盒段、第一加载转接板、第一端转接板、第一端钢板,以及第二加载盒段、第二加载转接板、第二端转接板、第二端钢板,向机翼盒段施加载荷,在该过程中,第一加载盒段底侧连接的第一端垫板与第一端支架支撑的第一端凸较间,可发生转动以及展向平动,而第二加载盒段连接的第二端凸铰与第二端支架支撑的第二端凹较间,仅能够发动转动,不能够发生展向平动,可保证能够平稳的对机翼盒段施加纯弯矩载荷,此外,能够在试验载荷较大时,保证试验的顺利完成。
