在側撞事故的比例不斷增加及提升乘員安全的要求下，側撞防護氣囊將成為車輛被動安全裝備最佳考量之一。為能充分有效設計安全的空氣囊糸統，氣囊的展開與相關影響參數對乘員安全的探討與分析更不可少，以能有效降低車輛碰撞時乘員之損傷。並且有效運用CAE的技術於車輛撞擊模擬與試驗的分析研究上，可達到增進產品設計開發之品質與效能，故為建立CAE模擬技術在車輛側面碰撞被動安全防護裝置的研發能量，本研究將以防側撞簾幕式氣囊為研究對象，首先依據CAE氣囊設計流程建構氣囊數值模型，並利用美規FMVSS201U頭部自由運動(FMH)進行簾幕式氣囊安全性的評估，並探討防護氣囊數值模型之氣囊袋型式、厚度及充氣器質量流率等參數對乘員安全防護的影響，以提供車輛防側撞簾幕式氣囊研發的參考。

As the accident of side impact increases and in order to raise the requirement of safety of occupant, the side airbag will become one of the best equipments of passive safety of vehicle. To efficiently design a safe airbag system, the discussion and analysis of the effect of deployment of airbag and relative parameters on safety of occupant must be implemented. Thus, the injury of occupant during vehicle impact can be reduced. Moreover, effectively use CAE techniques to study vehicle impact can increase the quality and efficiency of product development. Therefore, to construct the research and development energy of CAE techniques on protection equipment of passive safety in vehicle side impact, side curtain airbag was investigated in this study. First, the numerical model of curtain airbag was constructed according to the design procedure of CAE. The safety of curtain airbag was estimated according to FMH of FMVSS 201U, and the effect of parameters, such as type of cushion, thickness and mass flow rate of inflator on safety protection of occupant were investigated. The suitable design of mass flow rate of inflator of curtain airbag and thickness of curtain airbag were implemented to provide information for research and development of side curtain airbag.
