衛生署於民國97至101年的統計資料顯示事故傷害為1至14歲兒童的主要死亡原因。事故傷害致死的類型中，跌倒墜落發生率僅次於交通運輸事故。為研究兒童墜落行為進一步加以預防及保護，本研究使用廣泛在汽車工業中用以進行安全性測試的碰撞人偶進行兒童墜落行為的研究。
由於跌倒墜落時頭部與地面碰撞容易造成傷害甚至死亡，故頭部一直以來都是人體傷害研究的重點，為進一步探討墜落行為對頭部的傷害，使用現有的海伯三世六歲兒童人偶的頭頸部，搭配人體資料進行設計並製作具有軀幹、腰部、骨盆及大腿的台灣地區六歲實體人偶，人偶的各部位必須滿足重量、質心位置及轉動慣量要求，腰部也需通過靜態彎矩測試。
使用驗證後的人偶進行兒童墜落實驗，重現兩種兒童在家中可能發生的墜落情況，分別為由床上墜落以及由椅子上滑落，另外加上與床上墜落相同高度但不同身體傾斜角度的墜落情況進行比較。實驗過程中於頭部質心位置放置三軸加速規，並將墜落過程使用高速攝影機記錄。根據量測之資料，可以分析頭部可能的傷害及整個墜落運動過程。
實驗結果顯示新設計兒童人偶之特殊功用，使用此一新設計從事墜落測試，可以從中了解兒童運動過程，也可以預測可能發生的傷害。

According to statistics data of Department of Health, Executive Yuan, R.O.C., shows that falling and car accident are two major types of child fatal- injury. To analyze the child biomechanical response in falling can help to lessen the injury. Child anthropomorphic test device (ATD) is commonly used in automobile industries to improve the safety of vehicle. In this study, child ATD was design and chosen as an experimental device to analyze the children falling behavior.
Head impact might lead to serious injury or even death, so the head injury always is a focus point for researchers. To further explore the behavior of falling, a new child dummy which has the head and neck of Hybrid Ⅲ 6-year-old child dummy, featured with 6-year-old Taiwanese child’s torso, lumbar, pelvis and thigh, was developed in this study. All part of dummy is certificated in this study.
Two experiments, falling from bed and chair were conducted to demonstrate the performance of the newly designed dummy. Falling from bed and chair was two common accidents from children. Therefore, experiments based on these two situations were designed and conducted to demonstrate the performance of the newly designed child dummy. In both falling situation, the experiments from the different impact angle and height were also performed. The dummy head is instrumented with a 3-axis accelerometer to collect the head linear acceleration data in three directions during falling. In addition, a high speed camera was filming the process. Based on the acquired data, the possibility of the head injury and kinematic of falling can be analyzed.
In conclusion, the experiment results demonstrate the capability of the new child dummy developed in this study. By utilizing this dummy, kinematics of the child during falling can be realized and the possibility of injuries can be predicted.
