摘要:

头部运动是运动舒适性的关键决定因素,并且由于座椅和身体的柔顺性以及动态姿势稳定,头部运动与座椅运动存在显著差异。本文通过仿真比较了不同保真度的人体模型,将座椅加速度传递到头部,以评估运动舒适性。利用从高级人体模型(AHM)、计算高效人体模型(EHM)和实验研究中导出的频率响应函数,分析了六自由度动力学。动态驾驶仿真表明,人体模型显著影响预测的乘坐舒适性(增加高达3倍)。此外,使用文献中可用的滤波器和ISO-2631标准,人体模型对晕动症的影响适中(增加高达30%),但对主观垂直冲突(SVC)模型预测的晕动症影响更强(增加高达70%)。

英文摘要:

Head motion is a key determinant of motion comfort and differs substantially from seat motion due to seat and body compliance and dynamic postural stabilization. This paper compares different human body model fidelities to transmit seat accelerations to the head for the assessment of motion comfort through simulations. Six-degree of freedom dynamics were analyzed using frequency response functions derived from an advanced human model (AHM), a computationally efficient human model (EHM) and experimental studies. Simulations of dynamic driving show that human models strongly affected the predicted ride comfort (increased up to a factor 3). Furthermore, they modestly affected sickness using the available filters from the literature and ISO-2631 (increased up to 30%), but more strongly affected sickness predicted by the subjective vertical conflict (SVC) model (increased up to 70%).
