摘　　要：建立100MN快锻压力机多体接触非线性有限元分析模型,得到额定载荷下的应力分布,测试ZG20Mn试样疲劳寿命,拟合S-N曲线,引入快锻频率要求,预测额定载荷及工作频次下组合机架的疲劳寿命。结果表明:100MN快锻压力机结构合理,满足无限寿命使用需求。This paper establishes the multi-body contact non-linear finite element analysis model of the 100MN high-speed forging press to obtain the stress distribution under rated load,carries out tests of the fatigue life of the ZG20Mn specimen,fits the S-N curves and introduces the high-speed forging frequency requirements to predict the fatigue life of the combined housing under rated load and working frequency.The results show that the 100MN high-speed forging press is with reasonable structure and can meet the requirements of an unlimited lifespan.
