摘　　要：产品装配工艺是决定产品质量的关键因素。当前产品换代更新较快。新产品的装配多采用旧有产品的装配工艺或重新拟定装配工艺,经常出现装配工艺适应性问题。已有的产品装配工艺分析、优化研究针对的目标参数单一,未能综合装配工艺的多参数影响,实现产品装配工艺问题的全面分析和优化。论文在产品装配工艺影响要素分析的基础上,构建了装配工艺的全息模型,从6个角度对装配工艺失效进行了重新定义,总结得到引导其失效预测的特征关键词,最终提出面向产品装配工艺的失效预测方法及其应用过程模型。最后,应用论文提出的方法对一种实际产品的装配工艺进行了失效预测和解决,提高了产品装配工艺的可靠性。The product assembly process is a key factor in determining product quality.Due to fast update of product generations,the assembly of new products mostly uses the assembly process of old products or reformulates the assembly process,which often has the problem of assembly process adaptability.The existing product assembly process analysis and optimization studies target a single target parameter and fail to integrate the impact of multiple parameters of the assembly process to achieve a comprehensive analysis and optimization of the product assembly process.The paper constructs a holographic model of the assembly process based on the analysis of the influencing elements of the product assembly process,redefines the failure of the assembly process from six perspectives,summarizes the characteristic keywords that guide its failure prediction,and finally proposes a failure prediction method for the product assembly process and its application process model.Finally,the method proposed in the thesis is applied to predict and solve the failure of an actual product assembly process,which improves the reliability of the product assembly process.
