PFMEA控制程序 文件编号Document ID.: 版次Version: A/0 RX-QP-04 修改日期Revision Date: 页次Page: 9 /22 composition of the systems, subsystems or parts and components for specific FMEA activities.

A)系统FMEA的范围： A) System FMEA range:

一个系统可以看作是由各个子系统组成的。这些子系统一般是由不同的小组设计的。系统FMEA 的焦点是要确保组成系统的各子系统间的所有接口和交互作用以及该系统与车辆其他系统和顾客的接口都要覆盖。

A system can be regarded as composition of each subsystem. These subsystems are designed by different group generally. The focus of the system FMEA is to ensure that all interfaces and interaction among the subsystems composing the system and the interfaces of this system, other systems of the vehicle and the customer are covered.

B)子系统FMEA的范围： B) Subsystem FMEA range:

一个子系统FMEA通常是一个大系统的一个组成部分。子系统FMEA的焦点是确保组成子系

统

的各个部件间的所有的接口和交互作用都要覆盖。

A subsystem FMEA is a component of a big system generally. The focus of the subsystem FMEA is to ensure that all interfaces and interaction among the components composing the subsystem and the are covered.

C)部件FMEA的范围： C) Component FMEA range:

部件FMEA通常是一个以子系统的组成部分为焦点的FMEA。

Component FMEA is a FMEA taking the components of the subsystem as the focus generally. 5.8.3设计责任

填入整车厂(OEM)或本公司设计部门和小组。

Fill in the design department and group of the original equipment manufacturer (OEM) or the

PFMEA控制程序 文件编号Document ID.: 版次Version: A/0 RX-QP-04 修改日期Revision Date: 页次Page: 10 /22 company. 5.8.4编制者 5.8.4 Prepared by

填入负责编制FMEA的工程师的姓名、电话和所在公司的名称。

Fill in the name and telephone of the engineer responsible for preparation of the FMEA and the name of the company he works for. 5.8.5车年型/项目(产品型号)

5.8.5 Vehicle year type/project (product type)

填入所分析的设计将要应用和/或影响的车年型/项目或产品型号(如果已知的话)。

填入初次FMEA应完成的时间/日期，该日期不应超过计划开始生产的日期。

Fill in the time/date that the initial FMEA shall be finished and the date shall not exceed the date planned to begin production. 5.8.7FMEA日期 5.8.7 FMEA date

填入编制FMEA原始稿的日期及最新修订的日期。

Fill in the date compiling the original FMEA draft and the latest revision date. 5.8.8核心小组 5.8.8 Ginger group

列出有权确定和/或执行任务的责任部门的名称和个人姓名。

List the name of the responsible department and person with the right to determine and/or carry out the task. 5.8.9项目/功能 5.8.9 Project/function

PFMEA控制程序 文件编号Document ID.: 版次Version: A/0 RX-QP-04 修改日期Revision Date: 页次Page: 11 /22 填入被分析项目的名称和编号。用尽可能简明的文字来说明被分析项目要满足设计意图的功能， 包括该系统运行环境(如：规定温度、压力、湿度范围、设计寿命)及相关的信息(如：度量/测量变量)。如果该项目有多种功能，且有不同的失效模式，应把所有功能都单独列出。

Fill in the name and number of the project analyzed. Use the most concise words to explain that the project analyzed shall meet the design function, including the operating environment of the system (e.g.: specified temperature, pressure, humidity range and designed life (and related information (e.g.: measurement/measurant). If the project has multiple functions and different failure modes, all functions shall be listed separately. 5.8.10潜在失效模式 5.8.10 Potential failure mode

对于一个特定项目及其功能，列出每一个潜在的失效模式。前提是这种失效可能发生，但不是

一

定发生。

As to a specific project and its function, list each potential failure mode. The premise is that this kind of failure is possible to occur but not occurs certainly.

A)潜在失效模式是指零部件、子系统或系统有可能未达到或不能实现项目/功能栏中所描述的预 期功能的情况(如预期功能失效)。这种潜在的失效模式可能会是更高一级的子系统或系统的潜在失效模式的起因，或者是更低一级的零部件潜在失效模式的影响后果。

A) Potential failure mode refers to the conditions that the parts and components, subsystems or systems is likely fail to or can not to realize the expected function described in the project/function column (for example, expected function failure). This potential failure mode may be the cause for potential failure mode of a higher subsystem or system or effects of potential failure mode of a lower parts and components.

B)在确定潜在失效模式时，设计工程师们可以将对以往TGW(运行出错)研究、疑虑、报告和小 组头脑风暴结果的回顾作为起点。并同时将出现在特定的运行环境条件下(如：热、冷、干燥、灰尘等)和特定的使用条件下(如：超过平均里程、不平的路段、仅在城市内行驶等)的潜在失效模式也应予以考虑。
