摘要
运用试样测试及数理统计方法 ,对铁路机车车辆弹簧钢进行了试验研究 ,测定了材料试样的疲劳性能参数 ,得到了存活率、置信度为 95 %的 P- S- N曲线和修正的 Goodman疲劳极限线图。
With the sample testing and mathematical statistic method,the spring steel on railway locomotives and rolling stock is tested and researched,the fatigue characteristics parameters of the sample of material are measured,the P S N curve with the survival,confidence being 95% and the corrected Goodman fatigue limit diagram are obtained.
