基于方差分析法的飞机乘客座椅IFE舒适性设计研究

目的提出一种基于方差分析预测经济舱乘客所倾向座椅间距与IFE显示器高度的方法。方法通过辨识影响乘客座椅IFE舒适性体验的因素,对十六名对象进行测试,采用双因素重复实验方差法分析两个因素在三个不同条件下的变化,列出九种情况下乘客使用IFE显示屏舒适性评估的均值和标准差,得出自变量与因变量关系,从而得出经济舱乘客座椅间距与IFE显示器高度最佳值、适合值与经济值。结果舒适的座椅间距与理想的显示屏高度对舒适性有着显著影响,并且存在交互作用。经济舱乘客座椅间距为91 cm,显示屏上端距地面高为126 cm,乘客对IFE舒适性体验最佳;其次是座椅间距为86 cm,IFE高度为126 cm;最不舒适的是座椅间距81 cm,显示屏高度138 cm。结论研究结果对座椅间距与IFE显示屏高度进行了优化,为乘客座椅舒适性设计提供了参考。

Comfort Design of Aircraft Passenger Seat IFE Based on Analysis of Variance

The work aims to propose an approach for predicting the seat spacing and the IFE display height that economy class passenger prefers based on the analysis of variance. In the test on 16 subjects, the variation of two factors in three different conditions were analyzed in the method of double-factor repeated test variance, by identifying the factors affecting the IFE comfort experience of passenger seats. The average and the standard deviation of evaluated comfort of the IFE display screen used by passengers in nine conditions were listed to work out the relationship between independent variables and dependent variables, thereby figuring out the optimal value, suitable value and economic value of passenger seat spacing and the IFE display height in economy class. Comfortable seat spacing and ideal height of display screen affected the comfort significantly and there was an interaction between them. Passengers had the best IFE comfort experience when the economy class passenger seat spacing and the distance from the upper end of display screen to the ground were respectively 91 cm and 126 cm, followed by 86 cm seat spacing and 126 cm IFE height; while the worst case occurred when the seat spacing and display screen height were 81 cm and 138 cm, respectively. The results of research optimize the seat spacing and IFE display screen height and provide reference for the comfort design of passenger seats.
