| 摘 要： | 针对某柴油机飞轮壳由铸铁件改为铸铝件,装机300 h复合循环试验后,飞轮壳出现多处明显裂纹的故障,从理论和试验两方面对飞轮壳断裂的原因进行分析。分析结果显示:飞轮壳的结构设计不合理和铸造缺陷是造成飞轮壳断裂的主因。据此,改进了飞轮壳的结构设计和铸造方法,成功解决了飞轮壳断裂问题。

| Abstract: | The material of a certain flywheel-housing was changed from cast iron into cast aluminum, but some obvious crackles were found on the cast aluminum flywheel-housing after 300 hours combined cycle test. The theoretical simulations and tests were done to study the causes of the crackles. The analysis results showed that the defects of structure design and casting process were the main causes .Then the structure optimization was carried out and the casting process was improved, and the crackle problem of the flywheel-housing was solved successfully. |
