摘要
Abstract
The finite element analysis of corrugated metal sealing ring is taken to improve the sealability of corru- gated metal sealing ring, which is used in aviation engine. The variations of axial stiffness and radial size and the distribution of stress are compared, and then, a preliminary optimization design of the outline dimension of cor- rugated metal sealing ring, which based on its wave section, has been gotten. The observation and analysis of corrugated metal sealing stress show that stress distribution of circular arc wave section is rather uniform, and optimizing outline dimension of circular arc wave section and reducing the radial deformation and axial stiffness can improve the stability and service life of corrugated metal sealing ring. It is of reference and guidance signifi- cance for theory research and optimal design of corrugated metal sealing ring in aviation engine.关键词
