简介:采用计算机仿真和试验相结合的方法,根据ECER129法规在多刚体动力学分析软件(MathematicalDynamicModel,MADYMO)中建立Q3儿童测试假人和Facet儿童人体模型的正碰和侧碰仿真模型[1]。通过台车碰撞试验验证所建仿真模型的有效性,研究在侧碰情况下,Q3儿童测试假人和Facet儿童人体模型动态响应的差异性。仿真结果发现,在侧面碰撞时,Q3儿童测试假人回弹过程中侧倾角度明显大于Facet儿童人体模型,二者头部加速度曲线以及伤害值较为吻合,但胸部3ms合成加速度相差较大。研究结果表明,Q3儿童测试假人胸椎相比Facet人体模型刚度较大,Q3儿童测试假人胸椎、腰椎生物仿真度有待进一步提高。

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.
