简介:在L车型开发过程中,用ES-2型假人分别进行了FMVSS214和E-NCAP侧面撞柱试验.FMVSS214试验柱壁障从车辆碰撞侧偏前位置斜向侵入,E-NCAP试验柱壁障从碰撞侧垂直侵入.两种柱壁障侵入方式最终造成FMVSS214中假人向碰撞侧倾斜不明显,上半身受力时序依次为身体的上、中、下,且试验中座椅侧翼阻尼作用小,侧面安全气囊腹部位置易发生触底;E-NCAP中假人上半身有明显向碰撞侧倾斜现象,上半身受力时间比较接近,且座椅侧翼起到一定保护作用.试验结果表明,与现在执行的E-NCAP相比,在用ES-2型假人碰撞下,FMVSS214试验中假人胸部伤害相对偏小,腹部伤害相对偏大;在2015版E-NCAP侧面撞柱试验调整方案实施时,约束系统开发需要提高对腹部的保护作用.
简介:采用柱前衍生法和柱后衍生法测定紫芝药材中氨基酸成分,分析氨基酸分析仪(离子交换色谱分离-柱后衍生)和高效液相色谱仪(柱前衍生-反相液相色谱分离)在氨基酸测定上存在的异同。结果表明两种方法在测定同一样品时,在丝氨酸、异亮氨酸和脯氨酸等组分检测上的差异显著。
