Abstract:

In order to reduce the assembly work fatigue, reduce the intensity of action and improve the assembly quality and efficiency, a comprehensive evaluation model was proposed to evaluate feasible assembly sequences objectively based on human factor simulation analysis. Taking human factor performance of assembly sequences as the goal, a comprehensive evaluation index system including quantitative and qualitative indicators was created as well as human factor engineering simulation analysis model for assembly sequences was proposed, on the basis of it, the attribute value of basic index could be obtained by virtual simulation technology and human factor analysis method.The weights of quantitative index and qualitative index were determined by adopting objective and adaptive entropy method and fuzzy analytic hierarchical process respectively, qualitative evaluation value was quantified using triangular fuzzy number, then based on Topsis framework, the optimal assembly sequence can be drawn. Finally, the evaluation model was applied to a aerospace product reducer feasible assembly sequence optimization combined with Tecnomatix digital simulation platform, verifying its validity.

摘要：

为减少装配作业疲劳，降低动作强度，提高装配质量和效率，提出了一种基于人因工程仿真分析的装配序列综合评价模型。以装配序列的人因性能优劣为目标，创建了包含定量与定性指标在内的综合评价指标体系；提出了装配序列人因工程仿真分析模型，通过虚拟仿真技术与人因分析方法获取人因性能的基础指标属性值。采用客观自适应熵权法和改进模糊层次分析法分别确定各定量指标和定性指标的权重，利用三角模糊数定量化定性评价值，基于Topsis框架得到适合人体作业的最优装配序列。最后结合Tecnomatix数字化仿真平台将该评价模型应用于某航天产品减速器可行装配序列的优选，验证了方法的有效性。
