摘要:
刨削式防爬器的防爬性能直接影响其吸能的稳定性。基于EN 15227:2020《铁路应用铁路车辆车体的耐撞性要求》，采用LSDYNA软件的大变形碰撞仿真分析技术建立有限元模型，对刨削式防爬器的吸能特性和防爬性能进行研究，再通过刚性墙碰撞试验验证刨削力与压缩行程的关系，通过垂向加载试验测量残余塑性变形进而验证防爬器的防爬性能。研究表明：刨削式防爬器的吸能特性及防爬性能良好；仿真分析与试验结果误差在20％以内，具有较好的一致性，仿真分析结果真实可信，防爬性能研究方法实用可行。
Abstracts:
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.
