Abstract
The movement of track rope which was impacted by broken line was relatively complicated, it was difficult to get accurate analytical expression. In this paper, the simulation model of track rope was established by LS-dyna, the model analyzed the impact dynamic response of track rope and accurately determined the tension and sag of track rope. The expression of impact load was established based on the collision theory, and the impact dynamic process was analyzed based on a specific case, the results were compared with engineering calculation results. The results show that tension and sag of track rope which was calculated by the LS-dyna all meet the requirements. Compared with engineering calculation results, the error value within the scope of the permit, the simulation analysis was feasible and it could improve the level of safety construction.
