摘要
在ANSYS软件中,建立侧板的静力有限元模型和凸轮组的接触有限元模型,计算静载荷下的等效应力。在FE-SAFE软件中,将静力分析结果与已知的载荷谱相结合,考虑构件材料修正的S-N曲线,采用名义应力法计算并得出侧板和凸轮组的疲劳寿命。
In ANSYS software, the static finite element model of side plate and the contact finite element model of cams arebuilt, and the equivalent stress is calculated under the static load. Considering the correctional S-N curves of components ma-terial, and combining the static analysis results with the known load spectrums, the fatigue life of side plate and cams is calcu-lated and resulted by the nominal stress method in FE-SAFE software.
