| 摘 要： | 在民机结构强度设计及优化中，有限元模型作为一种数值计算方法已被广泛应用，并被业内所认可，但至今仍缺乏一套有效的有限元模型适航验证方法。本文从适航规章角度出发，探讨了有限元模型的验证思路和要求，梳理了验证要素，并给出了验证评价体系，可用于指导后续民机设计有限元模型适航符合性验证。

| Abstract: | As one of the numerical calculation methods, the Finite Element Model(FEM) has been used a lot in the civil aircraft strength design and structure optimization, and also been recognized as the most useful numerical calculation methods in the aviation domain. But still now on, there is no one effective way to validate FEM for certification. This paper solved this problem from regulation by discussing the FEM airworthiness certification requirements and methods to make sure the certification points and established the certification evaluation system finally. The method of verifying the FEM for certification can contribute for the future civil aircraft design. |
