摘要
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.
