中文摘要:

      目的 提高下肢障碍老年人在家居环境下使用轮椅的舒适度和自主参与性，从而满足老年人多层次生理和心理需求。方法 以情境分析和DEMATEL集成方法辅助创新设计决策为主，人机状态舒适度评价为辅。利用情境分析法对老年人、轮椅、家居环境情境要素和三者之间的交互关系进行分析确定情境冲突，建立设计规约，从而获取老年人轮椅期望需求指标;结合DEMATEL分析方法，识别和分析各需求要素之间的相互影响关系和在系统中的重要程度，从而指导设计实践;最后利用JACK仿真软件对设计方案进行人机舒适性分析验证。结论 通过情境分析和DEMATEL集成方法展开的老年人轮椅设计实践，设计方案通过了JACK虚拟仿真的人机舒适度验证，符合设计预期，为相关适老化轮椅产品设计提供一定的参考思路。

英文摘要:

      The work aims to improve the comfort and autonomous participation of the elderly with lower limb disabilities in using wheelchairs in the home environment, so as to meet the multi-level physical and psychological needs of the elderly. The integrated method of scenario analysis and DEMEL was mainly used to assist innovative design decisions, supplemented by human-machine state comfort evaluation. The scenario analysis method was used to analyze the scenario elements of the elderly, wheelchairs, and home environment and the interaction among the three, determine the scenario conflicts, and establish design protocols, so as to obtain the expected demand indicators of wheelchairs for the elderly. Combined with the DEMEL analysis method, the interaction relationship between the requirements elements and its degree of importance in the system were identified and analyzed, so as to guide the design practice. Finally, the JACK simulation software was used to analyze and verify the human-machine comfort of the design scheme. Through the integrated method of scenario analysis and DEMATEL, the design practice of the wheelchair for the elderly is carried out and the design scheme has passed the human-machine comfort verification of JACK virtual simulation, which is in line with the design expectations and provides a certain reference idea for the design of related age-appropriate wheelchair products.
