最新的C-NCAP测试工况包含了64 km/h的偏置碰及50 km/h的全正碰,对安全气囊的设计要求更高。基于某款从B级车平台开发的电动车,利用虚拟设计及CAE分析设计出满足C-NCAP碰撞5星目标要求的乘员侧气囊。通过气囊概念设计—车内爆炸模拟—静态展开试验—整车碰撞仿真的研究方法,获得整车碰撞优化配置参数,碰撞试验结果与仿真耦合理想。此项虚拟设计采用与物理验证相结合的方法,有助于高效地定义乘员侧气囊的设计参数。
The latest C-NCAP test conditions include a 64 km / h offset touch 50 km / h full nose, the design of the airbag higher requirements. Based on a certain type of electric vehicle developed from a B-class vehicle platform, a passenger-side airbag that meets the 5-star target requirement of C-NCAP collision was designed by means of virtual design and CAE analysis. Through the concept design of airbag - explosion simulation in vehicle - static unfolding test - the research method of vehicle crash simulation, vehicle collision optimization configuration parameters are obtained, and the result of crash test and the ideal of simulation coupling are obtained. This virtual design, combined with physical verification, helps to efficiently define the design parameters of the occupant’s side airbags.
