【摘要】：随着国际汽车工业的高速度、大规模发展,以发动机为代表的汽车零部件制造过程的监控及流程设计越来越受到重视,与之密切相关的测量数据的质量也日益备受瞩目。可以说,高质量的测量数据是设计研发、工艺验证、过程控制以及产品质量特性监控的前提和基础,而测量数据是否足够准确、可靠必须进行预先评估和确认。当前,汽车制造业公认的评估测量数据质量及测量系统能力的最有效的工具便是测量系统分析(Measurement Systems Analysis,MSA)。本世纪初我国的一些较大的汽车零部件制造企业包括潍柴动力股份有限公司正式引进了MSA。论文作者作为潍柴动力MSA项目的技术带头人,在长达十五年的时间里对其进行了全面深入的研究和探索,在整个公司内实现了“全流程、全工艺”的创新,为发动机新工艺的设计开发提供全面验证,对制造过程中的不良变差进行严密监控。“全流程”即从测量系统分析理念导入、方案设计、测量设备配置、过程数据验证等MSA运行全过程;“全工艺”即覆盖铸造、加工、热处理、装配等发动机研制工艺路线全过程。其中大量案例是对MSA的挑战性探索和创造性应用,如采用Rx-法、ANOVA法对测量系统的重复性与再现性进行分析;采用t检验法对扭矩测量系统的准确性进行判定;采用I-MR法对不可逆转、不可重复、破坏性测量系统进行稳定性分析;采用Kappa值-交叉表法对计数型测量系统进行一致性判定等,并通过自行设计的软件完成全部的数据处理与分析,真正将MSA从理论层面转为实践应用。本论文基于作者十五年来对MSA课题的深入研究和应用实施,以发动机制造流程为主线,对铸造、加工、装配等过程的典型测量系统分别选取适宜的分析方法定量评价测量系统的各项特性指标,以案例形式详细介绍了各类测量系统分析的设计方案、运算过程及评判标准。尤其是针对各类不可逆转、不可重复甚至破坏性的复杂测量系统,在MSA参考手册上没有给出具体指南的情况下,创造性地提出了自己的方案设计、评定标准以及实际验证效果,以期对MSA在汽车制造业中的具体实施提供一定的借鉴和参考。
[Abstract]:With the high speed of international automobile industry, large-scale development, monitoring and process design and auto parts manufacturing process to the engine as the representative of more attention to the quality of measuring data is closely related to the increasingly attention. It can be said that the measure of high quality is according to the design, process validation, the premise and basis of quality the characteristics of process control and monitoring products, and the measurement data is accurate enough, reliability must be pre evaluation and confirmation. At present, the most effective tool for measuring data quality ability evaluation and measurement system of automobile manufacturing industry recognized is the measurement system analysis (Measurement Systems, Analysis, MSA). At the beginning of this century, some of the larger car parts China's manufacturing enterprises including Weichai Power Limited by Share Ltd formally introduced MSA. as the author of Weichai Power MSA project technology leader in. In the fifteen years to conduct a comprehensive and in-depth study and exploration, in the whole company realized "the whole process, the whole process of innovation", to provide comprehensive verification for the design and development of new technology of the engine, the adverse variable in the manufacturing process of difference closely monitored. The whole process is the concept of import from the design, measurement system, measurement equipment, operation of the whole process of data validation MSA; "the whole process" that is covered with casting, machining, heat treatment and assembly process of engine development process. A large number of cases which is a challenge for MSA exploration and creative application, such as the use of Rx- method, ANOVA method the measurement system repeatability and reproducibility analysis; the accuracy of torque measurement system was determined using the t test method for irreversible; using the method of I-MR, can not be repeated, destructive measurement system stability analysis; Using the Kappa value method of cross table counting measurement system consistency, and complete the data processing and analysis all through the self-designed software, real MSA from the theoretical level to practical application. The author of this thesis is the implementation of further research and application of MSA project based on fifteen years, with engine manufacturing process as the main line of casting, machining, the characteristics of index evaluation method for quantitative analysis of suitable measurement system and selected typical measurement system of assembly process, in the form of case analysis is introduced in detail the design scheme of measurement system, operation process and evaluation standard. Especially for all kinds of irreversible, complicated measurement system can not be repeated or even destroy in nature, did not give a specific guide in the MSA reference manual on the situation, creatively put forward the design of their own programs, and verify the actual effect evaluation standard In order to provide some reference and reference for the specific implementation of MSA in the automobile manufacturing industry.
