基于ANSYS的回转式空气预热器接触式柔性密封疲劳寿命分析
摘要
基于有限元通用软件ANSYS的疲劳寿命分析方法
运用ANSYS的FATIGUE模块
将有限元方法和疲劳寿命分析理论相结合
对回转式空气预热器接触式柔性密封进行三维参数化建模
并编制APDL命令流
建立疲劳分析文件对回转式空气预热器接触式柔性密封进行了疲劳寿命分析。结果表明

Abstract
Adopting the fatigue life analysis method based on ANSYS
which combines the finite element method with the fatigue life analyzing theory by using FATIGUE module of ANSYS
a three-dimensional parameter model for contacting-type flexible seal on the rotary air preheater has been established
the APDL command stream being compiled
and the documents for fatigue life analysis being built
and then the fatigue life of contacting-type flexible seal for the rotary air preheater has been analysed.Results show that the fatigue life of contacting-type flexible seal for the rotary preheater is eight years.
