摘要
在对细节疲劳额定值(DFR)方法深入研究的基础上,对MA700飞机机身蒙皮典型对接结构进行了疲劳寿命分析,确定了该结构的载荷传递及一系列修正系数,得到了结构疲劳寿命分析结果。
On the basis of in-depth research on DFR method, the article conducts fatigue service life analysis on typical connection structure of MAT00 plane skin, determines the structure＇s load transmission and a series of correction coefficients, and obtains fatigue service life analysis results.
