摘要
在软件ANSYS中建立连杆的静力有限元模型,并计算其在静载荷下的等效应力。采用名义应力法,考虑连杆材料修正的S-N曲线,在FE-SAFE软件中,将连杆的载荷谱与静力分析结果相结合,计算得出连杆的疲劳寿命。
In this paper,the static finite element model of linkage is built in the ANSYS software,and the equivalent stressunder the static load is calculated. Combined load spectrums of linkage with the static analysis results,and considering thecorrectionalS-Ncurves of components material,the fatigue life of linkage is calculated and resulted in the FE-SAFE softwarewith the nominal stress method.
