| 中文摘要: |
| 基于两款汽车前保险杠原型，利用CATIA软件构建其三维几何模型，导入Hypermesh软件划分有限元网格构建有限元模型，利用50百分位成年男性行人下肢有限元模型，应用PAM CRASH软件进行碰撞求解。结果表明，侧碰时车型V2的前保险杠对行人造成的损伤较严重。所建模型各具代表性，能够应用于行人下肢模型的验证试验，同时为汽车前保险杠的结构材料及安全性设计提供了科学的基础数据。 |

| Based on prototypes of two kinds of front bumper,the geometric models were built by CATIA,the models were meshed by Hypermesh.Utilizing the simulated lower limbs model of 50th percentile male,the simulation collision tests were conducted with front bumper system and calculated by PAM CRASH.The test results indicate that front bumper of V2 does more harm to pedestrian if side impact happens.The built models are not only typical for applying to verification tests of simulated lower limbs models,but also providing a scientific basic data for the structural material and safety design of front bumper. |
