基于模糊FMECA的齿轮制造工艺可靠性分析
|
摘要
齿轮制造工艺失效导致齿轮在制造过程中的质量可靠性变差,利用模糊FMECA方法对齿轮的制造工艺进行可靠性评价,综合考虑失效发生频率、影响严重程度、检测难易程度、工艺改进程度等工艺失效模式的影响因素影响,在获得各失效模式的危害度定量排序以后,再将各失效模式作为影响因素对齿轮制造工艺进行二级模糊合评价。文中提出的是一种考虑齿轮制造工艺时的可靠性评价方法,在齿轮制造过程中提高了产品的可靠性。
The failure of gear manufacturing process leads to the deteriorating reliability of gears. The reliability of gear manufacturing process is evaluated with the aid of fuzzy FMECA, with such factors as failure frequency, impact, difficulty in the detection, process improvement and so on taken into account, which exert certain influence upon the failure mode of gear manufacturing process. The failure modes, with the quantitative sequence of their damage, are taken as the influencing factors to carry out the secondary fuzzy comprehensive evaluation of gear manufacturing process. In this article, a method of reliability evaluation is proposed, in order to enhance the reliability of products in the manufacturing process.
