| 中文摘要: |
| 在橡胶关节径向刚度过程能力提升六西格玛项目中，测量系统分析是保障数据可靠性的核心环节。以橡胶硫化仪、电子秤、二维试验机及外径测量仪4类关键测量设备为研究对象，针对橡胶关节径向刚度及相关关键影响因子（胶料Fmax及产品外径、质量）的测量需求，系统梳理了测量系统分析过程中出现的破坏性测试数据波动、测量位置敏感性、高精度设备线性和偏倚及测量变异阈值超标等典型问题。通过嵌套分析、标准化操作、综合判定标准及目标导向优化等解决方案，实现了测量系统的有效改进，所有设备最终满足测量要求。本工作总结的测量系统分析实践经验可为橡胶关节及类似橡胶弹性元件的测量系统搭建提供实用参考，助力六西格玛项目高效推进。 |
| 英文摘要: |
| In the Six Sigma project for improving the process capability of rubber bushing radial stiffness，measurement system analysis serves as a core step to ensure data reliability.Taking four types of key measuring equipment including rubber curemeters，electronic scales，two-dimensional testing machines and outer diameter gauges as the research objects，in response to the measurement requirements of rubber bushing radial stiffness and its related key influence factors（Fmax of the compound，outer diameter and weight of the product），the typical problems encountered during measurement system analysis implementation，such as destructive test data fluctuation，measurement position sensitivity，linear and bias of high-precision equipment，and exceeded measurement variation thresholds were systematically sorted out.Through targeted solutions including nested analysis，standardized operation，comprehensive evaluation criteria and goal-oriented optimization，the measurement system was effectively improved，with all equipments ultimately meeting the measurement requirements.The practical experience of measurement system analysis summarized in this work could provide practical references for the construction of measurement systems for rubber bushing and similar rubber elastic components，facilitating the efficient advancement of Six Sigma projects. |
