摘要

PRSEUS面板结构满足翼身融合飞机高升阻比、低油耗的设计要求。在有限元分析软件ABAQUS中，采用在蒙皮、法兰和裂带上设置不同偏移量的建模方法，比较不同壳单元偏移量对一阶屈曲特征值的影响，并通过对比试验结果获得准确的壳单元中立面偏移量，为类似板结构的精确建模提供参考。

Research on Setting Method of Neutral Plane Offset of Shell Element in PRSEUS Panel Structure Modeling

The PRSEUS panel structure meets the design requirements of high lift drag ratio and low fuel consumption of wing body fusion aircraft. In the finite element analysis software ABAQUS, the modeling method of setting different offsets on skin, flange and tear strap is adopted to compare the influence of different shell element offsets on the first-order buckling eigenvalues, and the accurate shell element neutral plane offsets are obtained by comparing the test results, It provides a reference for accurate modeling of similar panel structures.
