摘要

为了对装配序列进行合理评价，确保装配序列优选结果的正确性，提出一种装配序列多目标模糊综合评价方法.通过调研及专家知识构建装配序列多目标评价指标体系，并定义各指标的量化方法；用模糊层次分析法评估各指标间的相对关系，以获取较准确的装配序列指标权重；根据评价指标的量化方法计算可行装配序列各指标的初始值，并结合指标相应权重使用消除和选择转换法综合评价不同装配序列的优势值和劣势值，根据优势值和劣势值排序结果，从正反两方面综合选择出最佳装配序列.以某企业机床传动系统X轴装配序列优选过程为例，验证了该方法的有效性.结果表明，可行装配序列综合评价结果合理，优选出的方案具有较好的精度和效率.装配序列多目标综合评价方法计算过程简单，实用性强且评价结果合理，可用于一般机械产品的装配序列设计过程.

Abstract

To evaluate the assembly sequence reasonably and ensure the validity of assembly sequence selection results

a fuzzy comprehensive evaluation method for assembly sequence was proposed. Firstly

the multi-objective evaluation index system of assembly sequence was constructed by survey and expert knowledge

and the quantification methods of each evaluation index were defined. Then the fuzzy analytic hierarchy process method was used to evaluate the relative relation among the indexes so as to obtain more accurate weight of each evaluation index of the assembly sequence. Finally

the initial value of each index of the feasible assembly sequence was calculated according to the quantization method of the evaluation index. Combining the relative weights of indexes

the advantages and disadvantages of the different assembly sequences were evaluated by means of elimination and choice translating reality

and according to the result of priority and inferiority

the best assembly sequence was selected. Taking an assembly sequence optimization process of X axis of a machine tool transmission system in an enterprise as an example

the feasibility of the proposed approach is illustrated. This result shows that the comprehensive evaluation result of feasible assembly sequence is reasonable

and the optimized scheme has better precision and efficiency. The multi-objective comprehensive evaluation method of assembly sequence is simple and practical

and the evaluation result is reasonable.
