金属波纹封严环波纹数对结构强度的影响

摘要

In order to improve the mechanical properties of metallic sealing rings used in aviation engine,using finite element analyzing the stress distribution of three sealing rings with different sectional shape.Finally get the optimal dimension with excellent mechanical properties and preliminary plan of optimizing the structure strength by analyzing and contrasting those three finite element models.%为了提高航空发动机金属波纹封严环的力学性能,通过利用有限元方法对金属波纹封严环进行有限元分析.分别对三种不同截面形状的封严环的应力分布情况进行了对比,得到了关于航空发动机用金属波纹封严环初步优化结构方案.通过对三种模型的有限元计算结果进行对比分析,得到了一种具有良好力学性能的封严环外形特征.
