Abstract The difficulty in opening and closing the tailgate of sport utility vehicles (SUV) is important as one of the items of JD power’s Initial Quality Study (IQS). This study aimed to evaluate the perceived exertion and satisfaction in opening and closing SUV tailgates and explain them with the mechanical force. The study measured the mechanical open and close force for 33 SUV tailgates and evaluated perceived exertion and satisfaction of opening and closing with 84 male participants from 20’s to 50’s. The regression models of perceived exertion and satisfaction showed that initial closing and opening force, the difference between initial and maximum closing force, and the difference between an initial close angle and auto-fall angle should be small for a positive effect. In addition, the IQS score of tailgates is more related to perceived exertion and satisfaction in closing than those in the opening. The results of the study will be helpful to design and test the mechanical open and close structure of SUV tailgates.

SUV尾门开启与关闭的感知用力与满意度分析

摘要 作为JD power初始质量研究(IQS)的重要项目之一,SUV(SUV)后挡板的开启和关闭难度。本研究旨在评估打开和关闭 SUV 尾门时的感知用力和满意度,并用机械力对其进行解释。该研究测量了 33 个 SUV 尾门的机械打开和关闭力,并评估了 84 名 20 到 50 岁的男性参与者对打开和关闭的感知用力和满意度。感知用力和满意度的回归模型表明,初始闭合力和开启力、初始闭合力和最大闭合力之间的差异以及初始闭合角度和自动下落角度之间的差异应该很小才能产生积极的效果。此外,与打开时相比,后挡板的 IQS 得分与关闭时的感知用力和满意度相关。研究结果将有助于设计和测试SUV尾门的机械启闭结构。
