摘要:
轨道交通车辆铝合金车体加工件多为长大型材,出现过切事故后,若不能合理安排返修处理,则会造成较大的经济损失,并影响生产进度。为此,以铝合金车体机加工中出现的过切案例为分析对象,在满足设计和工艺要求的基础下,通过工件返修前后的功能分析及有限元分析,探讨 5 种常见的返修工艺方案及适用范围。
Abstracts:
The car-body processing parts of aluminum alloy rail vehicle are normally large profiles. In case of any over-machining,the invalid repair work arrangement will cause great economic loss and directly influence the cycle time. In this article,different over-machining cases of large aluminum alloy profile are studied,through the functions analysis before and after the car-body parts rework and via finite element analysis (FEA),5 kinds of common repair process schemes and their application scopes are discussed.
