Comfort evaluation for aircraft seat cushion based on finite element model

  • 摘要: 鉴于飞行员对飞机座椅的舒适性要求越来越高,针对人与座椅之间的应力分布这个座椅舒适性评价指标,建立了包括骨盆在内的人-座椅坐垫有限元模型,对坐姿下人与坐垫的应力分布进行了仿真计算.通过比较1g重力环境下仿真和实验坐垫上应力分布,验证模型的有效性,在此基础上开展了不同过载下的仿真计算.分析可知仿真模型在坐应力分布和应力值大小方面与实验数据具有较高的一致性;不同过载下体内以及坐垫上应力最大值与施加的过载加速度直接呈线性关系.结果表明,建立的人-座椅坐垫有限元模型是有效的,可以用于评估不同坐垫或不同过载环境下的舒适性.
