基于Kano模型与层次分析法的农机造型设计研究

Research on modeling design of agricultural machinery based on Kano model and AHP

为解决云贵地区因耕地面积小造成农业人员无法使用大型农机作业的问题,通过Kano模型对搜集的农机造型设计需求进行分析,得到优先功能需求与人机需求,在此基础上提出3种符合需求的农机造型设计方案,并使用三维建模软件Rhino对方案进行三维建模;运用层次分析法建立农机造型构成因子评价层次结构模型,邀请专家填写问卷进而求得准则层指标权重和方案层权重,选出最佳方案;运用Jack人机工程仿真软件对最佳方案人机需求指标进行仿真分析并检验是否符合人机工程标准。结果表明:结合两种方法进行产品设计并对设计方案进行人机检验,能够满足目标用户心理需求及生理需求,对其他产品创新设计有较大的借鉴作用。

In order to solve the problem that agricultural personnel cannot use large agricultural machinery operations due to small cultivated land area in Yunnan-Guizhou area, the collected agricultural machinery modeling design requirements were analyzed through Kano model. The priority functional requirements and man-machine requirements were obtained, On this basis, three kinds of agricultural machinery modeling design schemes that met the requirements were proposed. 3 D modeling software Rhino was used to perform 3 D modeling to the scheme. Hierarchical analysis method was used to establish a hierarchical model for the evaluation of agricultural machinery modeling constituent factors. Experts were invited to fill in the questionnaires to obtain the weights of criterion layer and scheme layer, and select the best solution. Jack man-machine simulation software was used to simulate and analyze the best man-machine requirements indicators of the best solution and verify whether they met the man-machine standards. The results showed that the product design combined with two methods and man-machine test of the design scheme could meet the psychological and physiological requirements of the target users. This had a greater reference effect on the innovative design of other products in the future.
