應用製程失效模式與效應分析於安全氣囊充氣殼體製程
The Application of Process Failure Mode and Effect Analysis to Airbag Inflator Housing Production Process
摘要
隨著汽車發展的不斷演進，人們對安全的重視程度正在不斷加深。安全氣囊這項技術終於在1990年被徹底重視起來，並以法律的形式進行普及推廣，到了1998年，美國國會頒布法令，要求從那年開始生產的所有車型必須在駕駛和副駕駛側都配備安全氣囊。現在，安全氣囊已被多數國家規定為必備的車輛被動性安全裝置之一。因此，安全氣囊的品質好壞會直接關係到汽車駕駛及乘客在事故中的人身安全。 在事前發現問題、找到解決方式方面，製程失效模式與效應分析（Process Failure Mode and Effect Analysis, PFMEA） 廣泛應用於製造行業產品生命週期的各個階段，而且普遍應用的工具。因此，本研究針對一家生產安全氣囊充氣殼體之公司，以失效模式與效應分析的方法來探討其安全氣囊充氣殼體製作流程中可能發生的各種問題（失效模式）及其造成的不良後果（效應）。期望可以在安全氣囊充氣殼體製作前有效避免這些潛在問題的發生，在生產階段裏，對所發生的失效及故障的原因解析，能快速的提供必要的資訊。使得個案公司因此有效降低因為製作流程問題所造成的損失或浪費。

Due to the continuous progress in vehicle development, people are paying more attention to the safety issue of the vehicle. One of the vehicle safety devices is airbag. It was not until the early 1990s that airbags became widespread in American vehicle. In addition, the United States Intermodal Surface Transportation Efficiency Act of 1991 required passenger cars and light trucks built after September 1, 1998 to have air bags for the driver and the right front passenger. At present, airbag is required as vehicle’s standard device by many countries.Failure mode and effect analysis (FMEA) has been proved to be an effective, proactive quality assurance method for the design of products or processes and applied to many industries or areas. In this study, a manufacturer of airbag inflator housing is selected as research subject. One type of FMEA analysis called Process Failure Mode and Effect Analysis, (PFMEA) is applied to the airbag inflator housing production process to identify potential problems (the failure modes) and its importance so that the case company can avoid potential problems and minimize loss.
