基于模糊综合评判的焊接变形影响因素评估研究

Welding Deformation Factors Based on Fuzzy Comprehensive Evaluation

将模糊综合评判应用于焊接变形影响因素评判中,定量分析并处理评估中的模糊性问题。在建立评估指标体系的基础上,构建二级模糊综合评判模型,对指标进行综合评价,求出评价等级量化值。模型计算结果表明,该方法具有较好的可行性。

The fuzzy comprehensive evaluation was applied to evaluate the index system of welding deformation influence factors. It made a quantitative analysis and dealed with the fuzziness of the assessment. On the basis of evaluation index system, the secondary fuzzy comprehensive evaluation model was built,which can evaluate the index comprehensively and get the rating quantitative values. The calculated results show that the method is feasible.
