Abstract

In order to make the tractor better meet the needs of users under the premise of satisfying the use of functions, the Kano - AHP model is used to design the appearance of the tractor. Firstly, the emotional needs of users are collected, and the tractor modeling is designed according to the requirements combined with the Kano model. The design scheme is displayed through Rhino in the form of three-dimensional modeling. According to the design requirement index summarized by Kano model, the tractor modeling hierarchical structure model was established by using analytic hierarchy process, the weights of each index were obtained, and the best design scheme was selected according to the weights. Finally, the selected best scheme was imported into Jack ergonomics simulation software for stress analysis and comfort analysis of the lower back, and the analysis results were used to check whether the scheme met the man-machine physiological standards.

为了使拖拉机在满足使用功能的前提下更好的满足用户需求，现使用Kano—AHP模型对拖拉机进行外观的造型设计。首先收集用户的情感需求，结合Kano模型并根据需求设计拖拉机造型，通过Rhino将设计方案通过三维建模的形式展现出来；结合Kano模型总结出的设计需求指标，使用层次分析法建立拖拉机造型层次结构模型，得出各指标权重，依据权重选出最佳设计方案。最后将选出的最佳方案导入Jack人机工程仿真软件进行下背部受力分析和舒适度分析，通过分析结果检验该方案是否符合人机生理标准。
