摘    要:针对现有产品装配过程中可靠性难以保证的问题,以灰色系统理论与多色集合理论为建模工具,提出可靠性驱动的产品装配过程建模方法。描述了影响装配过程可靠性主要工步的确定方法,分析了影响各工步的主要因素,详细阐述了各因素与各道工步之间关系矩阵的建立方法及影响装配可靠性主要因素的确定方法,提出了针对各主要影响因素的可靠性控制措施,从而达到产品装配过程可靠性驱动的目的。以某加工中心数控转台可靠性驱动的装配工艺过程控制为例证明了该方法的可行性。

关 键 词:装配过程  数控转台  可靠性驱动  灰色系统理论  多色集合理论

Abstract:For the problem of difficulty to guarantee products assembly process reliability, reliability-driven modeling approach of the assembly process was presented based on grey system theory and polychromatic sets theory. A method was described to determine the major assembly process step to public the reliability. Impact factors of each working step were analyzed. The methods to establish the relationship matrix between the various factors and the process step and to determine the main factors of the assembly reliability were elaborated. The control measures for reliability of the main factors were proposed. The purpose of reliability-driven for assembly process was achieved by above methods. An example of controlling assembly process for a machining center NC rotary table reliability-driven showed the feasibility of the method.
Keywords:Assembly process  NC rotary table  Reliability driven  Grey system theory  Polychromatic sets theory
