摘要
从理论上分析了振动时效激振力对白口铸铁工件疲劳寿命的影响,确定了白口铸铁疲劳破坏工件振动时效激振力的选择依据。此依据在大型铬钼冷硬球墨复合铸铁轧辊的振动时效中获得了成功运用。
Based on the analysis of the effect of excitation force of vibration aging on the fatigue life of white cast iron parts, the selection gist for excitation force was determined. This relationship has been proved right by application to large CrMo nodular compound chill cast iron rollers.
