汽车零部件主检具验证与试制质量关联性分析管控优化
Analysis and control optimization of the correlation between the verification and trial production quality of main inspection tools for automotive parts
汽车零部件的尺寸精度与装配一致性直接关系到整车性能与安全可靠性。主检具作为质量控制的核心工具，其验证精度对试制阶段质量表现具有关键影响。本文基于统计分析与系统工程方法，研究主检具误差传递与试制质量的耦合机制，并通过对副车架、仪表横梁等典型零部件试制数据的回归分析，揭示检具误差与尺寸失配、焊装偏移等缺陷的关联。研究提出“验证—监控—反馈”闭环优化模型，构建由检具设计验证、测量系统分析（MSA）、过程能力（CPK）管控及数字化追溯组成的质量协同体系，为提升试制阶段的尺寸稳定性和制造一致性提供了有效路径。
The dimensional accuracy and assembly consistency of automotive parts are directly related to the overall performance and safety reliability of the vehicle. As the core tool for quality control, the verification accuracy of the main inspection tool has a crucial impact on the quality performance during the trial production stage. Based on statistical analysis and systems engineering methods, this paper studies the coupling mechanism between the error transmission of the main inspection tool and the quality of the trial production. Through regression analysis of the trial production data of typical components such as the subframe and the instrument crossbeam, it reveals the correlation between the inspection tool error and defects such as dimensional mismatch and welding offset. The research proposes a closed-loop optimization model of “verification - monitoring - feedback”, and builds a quality collaboration system composed of tool design verification, measurement system analysis (MSA), process capability (CPK) control and digital traceability, providing an effective path for improving dimensional stability and manufacturing consistency in the trial production stage.
