【摘要】 烟用材料设计是卷烟设计的重要环节，直接影响卷烟焦油量及其稳定性。目前，烟用材料的设计方法相对单一，焦油量的稳定性相对较差，迫切需要应用新的技术和方法，本文提出在控制卷烟主流烟气焦油量中应用稳健设计技术。 首先，研究并全面总结了卷烟降焦油量技术和方法，为稳健设计技术的应用提供了卷烟降焦控焦专业基础。 其次，对稳健设计技术的基本理论进行了总结，重点阐述了静态稳健设计的基本程序，为稳健设计技术在烟用材料设计中的应用提供了思路和方法。 最后，在上述研究和总结的基础上，按稳健设计的基本程序，将整个设计过程分为系统设计、参数设计和容差设计三个阶段，对卷烟接装纸、嘴棒进行了优化设计。通过信噪比和灵敏度分析，最终确定了烟用材料的最佳组合方案；运用质量损失函数，对质量和成本进行平衡，最终确定了烟用材料的容差。 稳健设计技术在控制卷烟焦油量中的成功应用表明，该技术将在卷烟配方研究、卷烟工艺研究、卷烟过程控制、卷烟标准制定等方面有着良好的应用前景。更多还原

【Abstract】 The design of cigarette materials is a important tache of cigarette design ,and effects directly on the tar levels of cigarette and tar stability. At present, the design method of cigarette materials is relative single, which leads to low stabilities of the tar levels. Therefore, the application of new technology and method is urgent. In the paper, the application of robust design in controlling tar levels of mainstream smoke was presented.Firstly, the technology and method for reducing tar of cigarette were researched and overall summarized in order to offering professional foundation for the application of robust design in reducing and controlling cigarette tar.Secondly, basic theories of robust design were generalized, and the basic procedures of robust design of static character were emphasized, which provided an idea and way for the application of robust design in the design of cigarette materials.Finally, on the base of the above research and summarization, according to the basic procedures of robust design, the overall process of design were divided into three phases, i.e. system design, parameter design and tolerance design. At the same time, the design of tipping paper and filter was optimized. Through the analysis of the signal to noise ratio and sensitivity, the optimum combination scheme was ascertained ultimately. The quality and cost were counterpoised by using quality loss function, and the tolerance of materials was also ascertained in the end.The successful application of robust design in controlling tar levels of cigarette shows that the application of the technology is promising in the study of cigarette blending and making technology, the process control, and working out of the cigarette standard.更多还原
