車輛撞擊曲線是碰撞測試中一個可以代表車輛撞擊運動過程的重要量測數據，由反應車輛碰撞過程的撞擊曲線著手探討，除可清楚了解車輛在撞擊過程中的動態反應與能量變化外，並可研判乘員在撞擊過程中的損傷程度。本論文針對車輛的正面撞擊曲線進行研究，分析車輛撞擊測試中所量測的撞擊曲線特性，包含曲線形狀、振幅及時間歷程等參數，來探討撞擊曲線之形狀趨勢對乘員損傷程度的影響，進而提出可有效減少乘員損傷的撞擊曲線趨勢。撞擊曲線形狀趨勢之研究可提供應用於車輛安全性評估與抗撞設計的參考。

The vehicle crash pulse is an important measured data which can represents a time history response of a vehicle during an impact test. To investigate the crash pulse not only can realize the dynamic response and energy change of the impact process, but also able to assess the severity of occupant injury during a crash. The frontal vehicle crash pulse was investigated in this study. The characteristics of the measured crash pulse of vehicle impact test can be analyzed to discuss the effect of the crash pulse shape on the occupant injury. The shape, amplitude and duration characteristics of pulse were discussed herein. Furthermore, a better pulse shape to effectively reduce occupant injury was proposed. The pulse shape obtained in this study could help evaluate vehicle crash safety and guide the future development of safety technologies.
