摘要
由于组成汽车发动机的零件复杂多样,其装配的工艺过程就尤为重要,所以文章使用数学统计等方法来改进汽车发动机装配线上专机的工艺过程。文中首先对发动机装配线某专机的工艺过程进行FMEA分析,发现工艺缺陷,提出改进设计;然后使用QFD(quality function deployment)和FMEA(Failure modes and effects analysis)的协同设计方法对专机工艺进行了更加符合客户需求的改进设计,计算出改进设计重要度比重。最后经过比较,得出减少人工处理和提高PLC控制等工艺改进可以更符合客户需求。
As automobile engine is composed with complex and various parts, so its assembly process is particularly important, and in this paper mathematical statistics methods was used to improve the processes of special machine tools of the automobile engine assembly line. Firstly in this paper FMEA method was used for analyzing the process of the machine tools, and process defects was found, and improvement for design was put forward. Then the QFD and FMEA collaborative design was used to improving the process in more demand for customer, and the proportion of each improvement for design was then calculated. Finally after comparison, it was concluded that the reduce artificial processing and improve PLC control can be more in line with customer requirements.
