With the finite element method, a 3D-complicated wing structure was modeled in this paper to study the inherent dynamic characters of the wing structure, and the modes of first three orders under original support conditions were acquired by the mode experiment of a wing structure. Compared with the experimental result, the finite element theoretical calculation was verified to be valid.% 运用有限元手段建立三维复杂翼面结构的数值仿真模型，研究翼面结构的动力学固有特性，并通过原装支撑模态试验获得了翼面结构的前三阶模态参数，将理论计算与试验结果进行比对，验证了有限元模型计算的有效性。
