| 中文摘要: |
| 基于有限元分析进行一种塔形结构的轨道车辆用变刚度横向止档（简称横向止档）的结构设计。横向止档的橡胶部分采用两段式流线形型面组合，可以优化橡胶部分受载后的形态，避免橡胶部分弯折；通过改变横向止档的底部孔洞大小和形态以及金属底板的侧壁高度，可以灵活调整横向止档的刚度拐点位置，较好地满足设计要求。型式试验验证了横向止档的塔形结构的可靠性。本设计可为横向止档的结构开发提供参考。 |

| Structure design of a variable stiffness lateral stop for railway vehicle（referred to as lateral stop） with tower shaped structure was carried out based on finite element analysis.The rubber part of the lateral stop adopted a two-stage streamlined surface combination，which could optimize the shape of the rubber part after being loaded and avoid the rubber part breakage.By changing the size and shape of the bottom hole of the lateral stop and the height of the plate sidewall of the metal bottom，the position of the stiffness inflection point could be flexibly adjusted to better meet the design requirements.The type test verified the reliability of the tower shaped structure of the lateral stop.This design could provide reference for the structure development of lateral stop. |
