摘要:
应用Newmark β法,对汽车碰撞半刚性护栏进行简化计算,解决碰撞过程中的非线性问题.分别对不考虑汽车转动和考虑汽车转动建立了简化模型,对汽车碰撞护栏进行时程分析.通过与LS-DYNA有限元模拟结果对比表明,考虑汽车转动的简化计算方法能较准确地对碰撞过程进行时程分析,帮助护栏设计人员更清楚了解碰撞过程和碰撞作用机理,有利于护栏的优化设计.
Abstract:
A simplified calculation method on the basis of Newmark β is used to solve the nonlinear problem during the car crashing wave-beam semi-rigid barrier process. Time-history analysis is carried out by the simplified models with and without considering rotational in-plane degree-of-freedom. Compared with the LS-DYNA finite element simulation, it shows that the simplified calculation method can provide accurate time-domain analysis for the collision process by considering two translational and one rotational in-plane degree-of-freedom. The simplified calculation method helps the barrier designer to understand the collision process more clearly and make the barrier design more reasonable.
