摘要
针对汽车驾驶人机接触界面中的乘坐舒适性问题,依据人体生理学、解剖学和生物力学原理,通过对臀部和股区的解剖结构分析,提出了汽车人机界面的舒适体压分布的一般准则．在研制的汽车乘驾体位生物力学特性实验台上,进行了汽车驾驶环境的人机界面的体压分布实验和主观评价研究．4种曲面座垫的主观评价实验结果表明,座椅形面是影响乘坐舒适性的重要因素,不同形面特征的座椅具有不同的乘坐舒适性．客观评价实验结果证明,所提出的人机接触界面的体压分布准则是正确的,依据该准则能够评价人机接触界面中的乘坐舒适性问题．实验台中的分布式体压测试系统能够有效地测绘出不同座垫实验中的人机接触界面的体压分布曲线,并发挥出很好的测试作用．
According to the theory of human physiology, anatomy and biomechanics, the anatomical structure at buttocks and thigh area is analyzed to propose a general criteria on the comfortable body pressure distribution in man-machine interface. The experiments for body pressure distribution in driving environments and subjective evaluation are performed on a specially designed test stand. The experimental results from subjective assessment on four kinds of seat cushion indicate that the chair seat is an important factor affecting seating comfort, different chair seats are endowed with the corresponding seating comfort. The experimental results from objective assessment indicate that the presented criteria for the body pressure distribution in man-machine interface is sufficiently accurate to evaluate the seating comfort in man-machine interface. The distributed test system enables to survey and protract the body pressure distribution curve of different seat cushion effectively.
