基于3D打印的吸能式防爬器方案对比分析

Comparison and Analysis of Anti-Climber Schemes Based on 3D Printing

为抑制列车碰撞时的相互爬车程度,列车端部均安装集吸能与防爬功能于一体的吸能式防爬器。然而,现有防爬器的吸能结构大多采用传统工艺制成,其质量较大,设计空间较小,落后于现代轨道交通车辆轻量化的发展理念。近年来,随着3D打印技术的发展,能够通过材料层层累加的方式实现结构的制备。这种独特的制造方式可以实现高度复杂结构的自由生长成形,极大地拓宽了设计空间,为新型防爬器吸能结构的制备提供了强大的工具。

In order to restrain the train overriding in case of train collision,an energy-absorbed anti-climber with integrated energy absorption and anti-overriding function is installed at the end of the train.However,the existing energy absorption structure of anti-climber is mostly made by traditional technology,which has heavy quality and small design space,which lags behind the development concept of lightweight modern rail transit vehicles.In recent years,with the development of 3D printing technology,the structure can be prepared by adding layers of materials.This unique manufacturing method can realize the free growth and forming of highly complex structure,greatly broadens the design space,and provides a powerful tool for the preparation of energy absorption structures of new anti-creepers.
