数控机床可靠性试验中关键功能部件的提取研究
Study on Extraction of Key Functional Components in CNC Machine Tools’Reliability Tests
摘要
Abstract
In the reliability tests,due to the limitations of human resources and other factors,it was not able to test all components,but only to test the machine and its key components usually.Ai-ming at the problems of lacking theoretical basis and method for key functional components’extrac-tion in CNC machine tools’reliability test,this paper proposes a comprehensive extraction method based on three-parameter interval gray number.This method consider six factors including failure fre-quently,hazardous,maintainability,complexity,technical level,cost-effective,and their relationship comprehensively,combine the field data with expert experience,conduct a comprehensive assessment for each component with projection index function method,and then extract the key functional com-ponents in CNC machine tools’reliability test through Pareto Principle.At last,a domestic horizontal machining center is analyzed for an example to prove this method’s effectiveness.关键词
