Evaluation Index System of Human-Chair Adaptation of High-Speed Train Seat

In order to evaluate and analyze the human–machine adaption of high-speed train passenger seats, based on the results of high-speed train passenger comfort research, a comfort evaluation system for human–machine adaption is established, and the weight relationship of the indexes is determined using the G1 method. The analysis results show that the degree of influence on riding comfort is in the following order: size adaptation > position adaptation > angle adaptation > shape adaptation; the size, position, shape and angle of the lumbar support are the most significant factors affecting comfort. Passengers are most concerned about lumbar comfort when riding train seats; the size and position of the headrest, neck rest, and seat surface are also the main factors affecting ride comfort.
