摘要

本文首先论述了国内转向架的发展概况及其构成特点，由于车辆的用途不

同、运行条件的差异、制造维修方法的制约和经济效益等具体因素的影响，对转向架的性能、结构、参数和采用的材料及工艺等要求就有差异，因而转向架的造型方法各有其特点。其次，本文基于模块化技术、参数化技术及高级配合技术，利用SolidWorks 软件设计出SS 4型机车转向架各零部件的三维实体造型，通过高级配合技术完成转向架轮对、轴箱、轴箱悬挂装置、构架等各部件的装配，最后装配成为一台完整的SS 4机车转向架，为后续工程图的生成、强度分析提供所需的参数与几何实体模型。最后，本文通过有限元分析方法对转向架各零部件的强度进行分析，得到的结果，根据转向架的结构特点，采用局部修正方法调整转向架各零部件的基础模型至最终模型，并确定了相应的零件尺寸。在完成上述过程之后，可对转向架的所有零件外形及其装配顺序有很彻底的认识，从而为今后更深层次的分析研究打好基础，具有重要的学术价值和工程实际意义。

Abstract

This thesis starts with a general survey of the development of the bogie in domestic and its constitutional characteristic. Some factors such as vehicle s’ different purposes, operating conditions, manufacturing or maintenance methods and economic benefits lead to different requirements of bogies’ properties , structures, parameters and technology. So the bogies are characterised by various modeling methods .Then, a three-dimensional solid model for bogie of SS 4 locomotive was designed ,using SolidWorks software ,based on the modularization techniques,the parameterization technology and the advanced coordinate technology. This model provides the required parameters and geometric solid model for further study of engineering drawings generation, strength and analysis.Finally, the strength of bogie’s each component and part is analyzed using finite element analysis ,and the final model and each parts' dimensions are determined .These works mentioned above lay the foundation of further research, have important academic value and actual engineering significance.
