The invention belongs to the field of airplane structure strength testing, and particularly relates to a wing box section testing device. The device comprises a bottom beam (1) and a loading box section (3), a supporting stand column (8) is arranged on the bottom beam (1), and an actuating cylinder (2) is arranged on the outer side of the supporting stand column (8); the loading box section (3) comprises box section bodies (17) arranged at the two ends of the test piece (18), the two box section bodies (17) are erected on two supporting stand columns (8) respectively, a first convex hinge (61) is fixed to the lower end of the box section body (17) on one side, a concave hinge (4) is fixed to the corresponding supporting stand column (8), a force bearing base plate (9) is fixed to the lower end of the box section body (17) on the other side, and a second convex hinge (61) is fixed to the lower end of the force bearing base plate (9). Second convex hinges (62) are fixed to the corresponding supporting stand columns (8), and double lugs (14) are further fixed to the box section body (17) so as to be hinged to the loading end of the actuator cylinder (2). According to the invention, the strength test of the wing box section in a pure bending moment loading form is realized.

    本申请属于飞机结构强度试验领域,特别涉及一种机翼盒段试验装置。该装置包括底梁(1)及加载盒段(3),底梁(1)上设置有支撑立柱(8),支撑立柱(8)外侧具有作动筒(2);加载盒段(3)包括设置在试验件(18)两端的盒段主体(17),两个盒段主体(17)分别架设在两个支撑立柱(8)上,其中一侧的盒段主体(17)下端固定有第一凸铰(61),对应的支撑立柱(8)上固定有凹铰(4),另一侧的盒段主体(17)下端固定有承力垫板(9),对应的支撑立柱(8)上固定有第二凸铰(62),盒段主体(17)上还固定有双耳(14),以与作动筒(2)的加载端铰接。本申请实现了纯弯矩受载形式下的机翼盒段强度试验。
