| 目的 为了合理评价除雪机中多个设计因素对除雪机的影响，并选择出最优设计方案，建立将定性和定量相结合进行分析的除雪机设计方案评价模型。方法 针对除雪机的使用方式和应用特点，以及现有除雪机存在的问题，采用层次分析法(Analytic Hierarchy Process, AHP)和亲和图(JK)法对相关影响因素进行多层次的归类和总结，从外观、体验、人机和维护4个方面建立除雪机的多层级分析模型，并通过MATLAB辅助计算得到各影响因素的权重;然后运用模糊综合评价方法(Fuzzy Comprehensive Evaluation, FCE)对3个方案进行评分，形成各自的评分集和矩阵集并进行合成计算得到模糊评判结果向量，最终选择得到最优设计方案。结论 将该评价模型应用于3款除雪机造型设计方案评价中，应用实例分析表明该评价模型可以完成各设计方案的优劣排序，其评价过程客观准确，为后期除雪机的设计和优化提供量化分析参考。 |

| Abstract: |
| The paper aims to evaluate the influence of multiple design factors on the snow throwers reasonably, select the optimal design scheme, and establish evaluation model of snow thrower design scheme combining qualitative and quantitative analysis. Analytic Hierarchy Process (AHP) and Affinity Diagram (JK) were used to classify and summarize the related influencing factors according to the usage mode and application characteristics of snow throwers and the existing problems of snow throwers. The multi-level analysis model of snow plow was established from the aspects of appearance, experience, man-machine and maintenance, and the weight of each influencing factor was obtained through MATLAB assisted calculation. Then Fuzzy Comprehensive Evaluation (FCE) was used to score the three schemes, forming their own score set and matrix set, and then the Fuzzy Evaluation result vector was obtained through synthesis calculation. Finally, the optimal design scheme was selected. The evaluation model was applied to the evaluation of three snow thrower modeling design schemes. The analysis of application examples shows that the evaluation model can complete the ranking of pros and cons of each design scheme, and the evaluation process is objective and accurate, which provides a quantitative analysis reference for the design and optimization of snow throwers in the later stage. |
