Deformation space is affected by compartment packaging. The improvement suggestions are proposed to solve the problems existed in the current vehicle struc- ture and compartment packaging based on the areas that influence performance of automobile offset deformable barrier impact, such as the side rail, mounting, storage battery packaging,etc. It is proved that dO % offset crash simulation result of one certain car is well-correlated with the physical test. Optimization cases meet the crash performance requirements. The objec- tive of the analysis is to guide structural design and improves a car＇ s crash safety performance.展开更多
64 km/h 40%正面可变形壁障偏置碰撞是中国新车评价规则(C-NCAP)和欧洲新车评价规则(Euro-NCAP)测试重点考核的项目。为解决某车型在这种碰撞中存在的踏板侵入量严重超标问题,该文使用整车碰撞仿真模型,计算了踏板安装区域的变形程度,...64 km/h 40%正面可变形壁障偏置碰撞是中国新车评价规则(C-NCAP)和欧洲新车评价规则(Euro-NCAP)测试重点考核的项目。为解决某车型在这种碰撞中存在的踏板侵入量严重超标问题,该文使用整车碰撞仿真模型,计算了踏板安装区域的变形程度,分析了机舱纵梁的变形模式,优化了车身结构,增大机舱左纵梁的吸能效果和优化变形模式,加强中央通道区域的强度。仿真验证的结果表明:优化后碰撞中,油门踏板后移量降低了48.5%,上移量降低了29.1%;降低了踏板安装区域结构的变形,降低了踏板侵入量。因此,该优化方案解决了踏板侵入量超标问题,提升了整车安全性能。展开更多
