| 中文摘要: |
| 按标准在双帽型薄壁梁件的前端设计了V型诱导结构,并根据非线性有限元法的基本理论,运用非线性有限元软件ANSYS/LS-DYNA,针对原双帽型薄壁梁件和已经设计了诱导结构的双帽型薄壁梁件,在受轴向冲击载荷状态下的耐撞性能进行了数值模拟对比,验证了典型薄壁梁件中诱导结构对提高耐撞性的重要性. |
| 英文摘要: |
| Abduction structures of V slot in the front of the double-cap girder have been designed according to the basic theory of non-linear finite element analysis method.By using the non-linear finite element software ANSYS/LS——DYNA,the crashworthiness of thin girder with the abduction structures of V slot and without the abduction structures under the condition of axial impact load are computed.Compared with each other,the abduction structure in type thin girder is very important which can effectively control the peak force. |
