摘要：

研究3 岁儿童乘员模型的差异性对儿童安全约束系统（CRS）防护性能评价的影响，基于ECE R129 法规正面台车碰撞试验方法，采用Q3儿童假人和THUMS 3YO儿童人体有限元模型，建立不同类型的儿童约束系统（CRS）约束的正面碰撞台车试验仿真模型。对比分析了Q3 和THUMS 3YO 有限元模型的运动学响应以及头部、颈部和胸部损伤物理参数。结果表明：在前护板式CRS中，Q3 绕前护板向上翻转运动，THUMS 3YO 整体呈下潜运动。在相同CRS 约束条件下，THUMS 3YO 模型在颈部弯曲角度、胸部压缩量和胸部合成加速度均大于Q3。结果表明：相比于Q3 模型，THUMS 3YO 的颈部与胸部更具有柔韧性，生物逼真度更高。本研究可为儿童假人的发展提供依据。

Abstract:

The influence of the deference of the 3-year old finite element (FE) model on the evaluating performance of the Child Restraint System (CRS) was analyzed. Q3 dummy FE model and THUMS 3YO Human FE model were used to develop front sled test FE simulations with different types of CRS based on ECE R129 regulation. The kinematic behaviors of the FE models were compared, as well as the injury parameters of neck bend angle, chest deflection and chest resultant acceleration. The results show that in front-impact- shield CRS, Q3 were flipped upward, while THUMS 3YO with a motion of declination. The injury parameters of neck bendingangle, chest deflection and resultant acceleration of the THUMS 3YO were larger than Q3. The study shows that the neck and chest of THUMS 3YO FE model are more flexible and less stiffness than Q3 dummy FE model.This conclusion can be as reference for the future application and development of child dummies.
