摘要/Abstract

摘要： 根据联合国欧洲经济委员会制定的UN R129法规儿童约束系统（CRS）台车侧面碰撞条件，提出了2种台车侧面碰撞仿真试验方法，并验证了其可行性。基于该试验方法，采用Q3儿童假人，建立3种不同CRS（五点式-成人安全带固定（三点式CRS），五点式-ISOFIX固定，前护板型-成人安全带固定）的侧面碰撞数值分析模型。分析了儿童乘员的运动学响应和头、颈部及胸部的损伤物理参数。结果显示：儿童乘员在不同类型的CRS中的运动学响应不同。ISOFIX固定条件下儿童头部损伤风险较大，除三点式CRS约束条件下的儿童乘员损伤物理参数接近耐受极限值外，其他2种工况下的儿童乘员的胸部合成加速度（3ms）和上颈部弯矩值均超过儿童乘员耐受极限值，可见在侧面碰撞中儿童乘员的胸部和颈部损伤风险较大。

Abstract: According to the side impact conditions of UN R129 children restraint system, 2 kinds of simulation test methods were developed and the feasibility was verified. Based on the validated test method, the numerical simulation of side impacts in 3 different restraint systems (five-point-car seat belt, five-point-ISOFIX and shield-car seat belt) with Q3 child FE dummy model was adopted. The kinematic response of the child occupants and the physical parameters of head, neck and thorax were analyzed. The results show that the child occupant kinematics is different in various types of CRS. The injury physical parameters of child head in the ISOFIX CRS are the highest. Chest acceleration (3ms) and neck bending moment value of child occupants in the ISOFIX CRS and shield CRS are much higher than children's injury tolerance limit. The chest and neck of a child occupant in a side impact are subjects to high injury risks.

Key words: UN R129;side impact;test simulation method, injury risk, child restraint system（CRS）
