文章首先利用Hyper mesh软件建立了列车双级式吸能防爬装置的有限元模型,并基于该有限元模型对蜂窝结构强度对双级式吸能防爬装置耐撞性的影响进行了研究分析。结果表明,该吸能结构可以形成有序的变形模式。初始峰值力和平均撞击力随着蜂窝A强度或蜂窝B强度的增加而增加。该结构能量吸收量主要受蜂窝A强度影响,而蜂窝B强度则对初始峰值力有较大影响。
In this paper, the finite element model of double-stage energy-absorbing anti-climbing device is established by using Hyper mesh software. Based on the finite element model, the influence of the strength of honeycomb structure on the crashworthiness of two-stage energy-absorbing anti-climbing device is analyzed. . The results show that the energy-absorbing structure can form an orderly deformation mode. The initial peak force and the average impact force increase with the increase of the honeycomb A strength or the honeycomb B strength. The energy absorption of the structure is mainly affected by the strength of the honeycomb A, while the strength of the honeycomb B has a greater impact on the initial peak force.
