Anti-bending design method of airplane single lap structure test article

The invention relates to an anti-bending design method of an airplane single lap structure test article. The anti-bending design method comprises the steps that an integral inner side plate symmetrical structural member and an integral outer side plate symmetrical structural member are designed, and are connected together by a connecting bolt in an examination area; two anti-bending side plates are disposed in the examination area to form a single lap structure anti-bending test article. The anti-bending design method of the airplane single lap structure test article is advantageous in that one single lap structure is designed to be in a connection structure form having two single lap surfaces and two integral symmetrical test articles; a technical defect of difficulty in eliminating the outward bending of the single lap structural surface is solved; a theoretical basis is correct, an engineering concept is explicit, a force transmission route is clear, the design of the test article is simple, and execution
