对某型柴油机曲轴的过渡圆角三圆弧结构改为单圆弧结构进行了曲轴弯曲和扭转强度对比分析，并进行了有限元分析比较，得出柴油机曲轴的过渡圆角由三圆弧改为单圆弧结构，能有效减小过渡圆角处的应力集中。
對某型柴油機麯軸的過渡圓角三圓弧結構改為單圓弧結構進行瞭麯軸彎麯和扭轉彊度對比分析，併進行瞭有限元分析比較，得齣柴油機麯軸的過渡圓角由三圓弧改為單圓弧結構，能有效減小過渡圓角處的應力集中。

The paper made a comparative analysis of crankshaft bending and transverse strengths in single circular arc modified from three circular are in transitionary circular bead and compared them by finite element analysis, which concluded that the single circular arc modified from three circular arc in transitionary circular bead can decrease effectively stress concentration here.
