Q3 Child Dummy

Model

    Q3

Use

    As the successor of P series, the Q differs considerably from the P-dummies. It is not only advanced in terms of its biomechanical and anthropometric characteristics, it is also developed to be used in both front and side impact testing, making it the first "multi-directional" (child) dummy. The Q series can be equipped with accelerometer, angular velocity transducer, load cell, displacement transducer, etc. to evaluate the injuries suffered in crash tests. The instrumentation is interchangeable within the dummy and between other members of the Q-series.

Features

         In order to make the child dummies easy to assemble and disassemble, SAF has optimized the structure of the dummies which can be quickly assembled and disassembled. SAF has also minimized the impact of the transducers on the movement of the dummies, and protected the transducers and cables in good working condition.

    As the successor of P series, Q3 child dummy is the earliest developed dummy among Q series. Its potential application areas (including side impact test), biofidelity and injury assessment ability are all much better than TNO and P3 child dummy.

头部--主要由聚氨酯合成材料制成,在头颅内可以安装线性加速度传感器和角速度传感器。
颈部--柔性颈部允许在所有方向上的剪切和拉伸,分段设计可以防止翘曲,并允许适当的旋转。颈部中心装有钢丝绳,可以防止高负载下失衡。六轴测力传感器可以安装在颈部-头部和颈部-胸部的连接界面。
胸部--由聚氨酯骨架及皮肤组成。胸部位移情况由位于肋骨上的位移传感器来测量。柔性肩部连接到胸部,允许产生一定的形变。加速度传感器安装在胸椎,用于测量线性加速度。此外,还可以更换肩部来实现侧面碰撞测试。
腹部--腹部用PVC皮肤覆盖并由泡沬填充,腹部刚度由儿童的生物力学数据来确定。
腰椎--腰椎是一根柔性橡胶柱,腰椎可以在所有方向上承受剪切力和弯曲力。六轴测力传感器安装在腰椎和盆骨之间。
骨盆--Q系列假人骨盆有可移动的髋关节。加速度传感器可以安装在骨盆中。特殊的髋关节结构可使假人站立。
腿部--膝关节可以在任何位置锁定,该特征便于将假人定位在站立位置。注意:假人不能在无支撑的情况下站立。
手臂--手臂由上部和下部组成,通过肘部关节相连。肩关节是球形结构,允许一定范围内自由转动。
