Abstract: The anti-climbing performance of planing anti-climber directly affects the stability of its energy absorption. According to EN 15227:2020 Railway Applications—Crashworthiness Requirements for Rail Vehicles, the large deformation collision simulation analysis technology of LS-DYNA software is used to establish the finite element model, the energy absorption characteristics and anti-climbing performance of plan-ing anti-climber are studied. Then, the relation between plan-ing force and compression stroke is verified by the rigid wall crash test, and the residual plastic deformation is measured by the vertical loading test to verify the anti-climbing performance of anti-climber. Research shows that the anti-climbing performance and energy absorption characteristics of planing anti-climber are good. The error between simulation analysis and test is within 20% and has good consistency. The simulation analysis results are credible, and the research method of anti-climbing performance is practical and feasible.
