Collision Performance Analysis of Composite Anti-collision Fender for Bridges

  • 摘要: 采用试验和计算机仿真相结合的方法,研究复合材料防撞护舷在冲击荷载作用下的动力学特性。首先进行防撞护舷试样冲击试验,获得试样不同工况下的动力学响应;然后采用有限元法对试样进行数值模拟,通过与试验结果对比,获得相对精确的有限元计算模型,为实际结构参数的合理选取提供依据;最后运用ANSYS/LS-DYNA平台进行显式非线性分析,研究防撞护舷实际结构在碰撞过程中能量变化、接触响应和损伤变形等特征,得到了防撞护舷能量吸收和变形响应特性,各项数据均达到国家技术要求,为今后防撞护舷结构的优化设计提供理论支持。
