8、ses appear in the cause section of the DFMEA, the should also appear in the Cause section of the PFMEA 同樣的方式，干擾在DFMEA的原因部分出現(xiàn)，也應該在PFMEA的原因部分出現(xiàn),Noise Factor Management Strategy噪聲干擾因素管理策略,The team needed to review each of the Potential Causes for Failure listed in the G8D or the PFMEA and determine the

9、 appropriate Noise Factor Management Strategy. 小組需要評審在G8D或PFMEA中所列失效的每一種潛在原因，確定適當?shù)脑肼暩蓴_因素管理策略,Factors Affecting Process Capability因素影響過程能力,An initial Process Capability Study needed to be conducted. 需要進行初始過程能力的研究 The tensioning operation and the subsequent measurement of tension would potentially be

10、affected by ambient audible noise. 張力調(diào)整和隨后張力的測量會潛在地受周圍可聽見噪聲的影響,Measurement System Analysis測量系統(tǒng)分析,Before conducting any study, confirmation is required that the measurement system performance is acceptable. 在做任何研究之前，需要確認測量系統(tǒng)的性能是可接受的。 If the performance of the measurement system, is not satisfactory,

11、then any Production Validation conducted using the measurement system may not be valid. 如果測量系統(tǒng)的性能不滿意，那么使用該測量系統(tǒng)進行的任何生產(chǎn)確認都可能無效。,Gauge R that is, at vehicle, system, sub-system and component levels. 驗證和確認應該發(fā)生在系統(tǒng)工程V模型的所有級別上，也就是說，在整車、系統(tǒng)、子系統(tǒng)和零部件級別上。 The focus of verification should be on the lower levels

12、of the Systems Engineering V model. 驗證的焦點應該在系統(tǒng)工程V模型的較低級別上。,Summary Testing Type總結(jié)測試類型,Verification is a team-based process that includes representatives from all key areas involved. 驗證是一個以團隊為基礎的過程，包括來自所有參與領域的代表 Process Capability and Measurement System Analysis are an integral part of Production Val
