摘要
对行人与汽车碰撞中头部保护研究方法进行了分析,建立了行人头部与发动机罩碰撞的数学模型和有限元模型,并进行了试验验证。利用该模型研究了发动机罩参数的变化对行人头部伤害的影响。
Based on the introduction and analysis of research methods about pedestrian head protection, this paper builds the mathematics equations and FEA models and compares the calculating results with the test results about the collision models between the pedestrian head and the engine hood. The hood factors affecting the head injury were analyzed, which include the position of impact, the thickness of the hood, curvature radius of the hood, the length of the hood and the material of the hood and so on, and the ameliorating methods for the head protection were given.
