| 摘 要： | 某四缸柴油机在可靠性试验中出现平衡轴壳体断裂,对壳体进行模态分析,发现壳体刚度不足,模态频率低,在平衡轴不平衡量产生的旋转惯性力交变负荷下,发生断裂。通过优化壳体结构,提升模态频率。改进后样件通过了可靠性试验,解决了平衡轴壳体断裂问题。

| Abstract: | The balance sh aft housing break in four cylinder diesel engine reliability experiment process, modal analysis for balance shaft housing. Find out the stiffness insufficient, modal frequency low, balance shaft of unbalanced mass generate rotation inertia alternating load, then the break happened. Optimized the structure of the housing, promote modal frequency.Passed the reliability experiment, problem was solved. |
