兰州交通大学车辆工程专业毕业论文30t轴重货车转向架摇枕的结构及设计

摘要

随着我国铁路运输向高速和重载方向发展，转向架摇枕的运用条件日趋苛刻。因此，研究重载运输条件下的摇枕结构及其性能变得尤为重要。本文通过国内外重载运输的发展现状的了解,分析了国内外现有重载货车转向架的结构特点和性能。首先对我国30t轴重转向架进行了结构选型，初步确定了适应我国国情的30t轴重货车转向架的基本结构型式。重点对该转向架的摇枕的结构进行自主设计与分析。

运用SolidWorks建立30t轴重货车转向架摇枕的三维模型，并且详细介绍了该转向架摇枕的结构特点及设计步骤，其中包括了外壁和内部筋板厚度、排水口、漏沙孔等工艺孔、摇枕斜楔、15旁承台座、16弹簧承台、心盘部位、摇枕吊耳。然后对该摇枕进行了有限元应力分析，然后根据分析结果确定摇枕的薄弱地方并进行改进，最终设计得到满足强度要求，并有足够抗疲劳性能的转向架摇枕。
