Abstract
面对新一代航天类产品高质量、高效率、高效益的研制及发展需求,复杂、高精度的装配工艺过程是制约产品批量交付的关键影响因素.为提高某航天锥形舱段产品的装配效率与质量,基于六西格玛方法的工艺优化技术,通过开展定义、测量、分析、改善和控制 5 个阶段的研究,确定了影响装配的关键因子,并通过试验设计与分析计算得出最优工艺参数.经实际生产应用验证后,产品一次装配合格率由 47.1%提高至96.6%,既满足了产品高精度指标的设计要求,又实现了低成本、高效化的产品交付,为大批量生产奠定了基础.
In the face of the high quality,high efficiency and high benefit research and development needs of the new generation of aerospace products,the complex and high-precision assembly process is the key influencing factor re-stricting the batch delivery of products.In order to improve the assembly effi-ciency and quality of a conical space module,the key factors affecting assembly were determined through five stages of definition,measurement,analysis,im-provement and control based on the process optimization technology of six Sigma method,and the optimal process parameters were obtained through experimental de-sign and analysis.After the actual production application verification,the product assembly pass rate increased from 47.1%to 96.6%,which not only meets the design requirements of high-precision indicators of products,but also real-izes low-cost and high-efficiency product delivery,laying the foundation for mass production.
