摘要

車輛安全設計是希望能減少因行車事故所造成的各種傷害，本研究應用人偶傷害指數值，對車輛的安全性能做評估和改良。
因為前碰撞是所有事故發生率最高的，故論文主要考量前碰撞，應用Hybrid III人偶以及市售轎車模型進行前碰撞模擬分析，分析結果先與文獻做對照，確認分析模型預測評估值的合理性，再對車體重要結構、人偶傷害指數，進行最佳化，使其改善車體的碰撞安全性能。
研究結果顯示，車前潰縮樑的厚度和形狀都對車體的碰撞安全性能有很大的影響，在最佳化設計後，有效地改善人偶頭部傷害指數(HIC36) 10% 以上，並降低損傷級數(AIS)的等級由1級到最小、最好的0級。

Designing for the vehicle safety is intent to reduce the severity of injury to passengers or to the vehicles. The study uses injury index of dummy as a design criteria to improve the vehicle safety.
Among all the crashes, the frontal impact has one of the highest occurrence rates; therefore, the frontal impact is used as the major functional performance considered for the design improvements. In the study, dummy Hybrid III is used. The analysis results are compared with those in the literature to verify the accuracy of the analysis model, and then the analysis model is further used for optimization to improve the crashworthiness of the vehicle using injury index of the dummy.
The results from the study show the thickness and shape of the front rail have great effect on the vehicle crashworthiness. After the optimization, the dummy head injury index is reduced more than 10%, and the injury scale is improved from level 1 to a smaller and better scale of level 0.
