摘　　要：基于SAE标准理论,结合GB 10000标准中定义的中国人体身高、各关节尺寸等参数,从关节舒适性维度重点对11个百分位人体及其在不同H30(坐高)下对应H点位置进行分析与统计,得出H点分布图。并以这11个不同百分位人体拟合函数为样本做出多维正态分布,构建关于正常驾驶姿态下H点坐姿舒适曲线数学模型,对其他非特定百分位人体H点坐姿舒适曲线做出预测。同时为便于研发使用,将人体下肢简化为二维模型进行理论分析,获得H点二维理论模型曲线,并分析其与拟合函数间误差进而加以修正。Based on SAE standard theory and combined with parameters such as Chinese human heights and joint dimensions defined in the GB 10000,11 percentile human bodies and their corresponding H-point positions at different H30(sitting heights)are analyzed and counted from the dimension of joint comfort to obtain the H-point distribution map.The 11 different percentile human body fitting functions are used as samples to get the multi-dimensional normal distribution,a mathematical model of H-point sitting comfort curve under normal driving postures is constructed,and the H-point sitting comfort curve of other non-specific percentile human bodies is predicted.At the same time,to facilitate the research and development,the lower limbs of the human body are simplified into a two-dimensional model for theoretical analysis to obtain the H-point two-dimensional theoretical model curve,and the error between it and the fitting function is analyzed and then corrected.
