摘　　要：一个性能优良的驾驶座椅除了为驾驶人员提供一个与人体生理特点相适应的舒适而稳定的坐姿、良好的视野位置、具备一定的操纵空间和安全空间外,最重要是减轻传给驾驶人员身体的振动和冲击,满足振动舒适性评价标准.本研究利用模糊综合评价法,提出了汽车振动舒适性指标体系,旨在通过模糊综合评价法对汽车振动舒适性进行综合评价。本文运用多目标多级模糊综合评价的过程.先从最低层的评价指标开始逐层向上评价,直到总的评价目标为止.。结论证明该方法克服了ISO2631标准的缺点,较好地解决了不同车速、不同测点、不同路面及驾驶员操纵特征等多重因素带来的汽车振动舒适性难以评价和比较的问题。为汽车振动舒适性的评价提供了一种有效的方法。A excellent driver seat can not only make the driver comfortable, offer good visual field and safe room, but also lighten the vibration and concussion passing to the driver. The index system of the vibration comfort of automobile is proposed, and an overall evaluation on the vibration comfort of automobile is carried out, using the fuzzy estimate method. The method has overcome the shortcoming of ISO2631, figured out the problems of different speed, different testing position and different road situation, which make the vibration comfort of automobile difficult to evaluate and compare. Provided a kind of effective method for the valuation on the vibration comfort of automobile.
