转向架是保证高速动车组平稳、安全运行的基础。它是车辆的重要组成部分之一，所以它的可靠性影响整个列车的平稳运行。这就需要对转向架结构进行分析了解，掌握转向架零件的实体造型方法和虚拟装配方法。 本文主要在对CRH380B动车组转向架进行结构分析的基础上，了解转向架的基本结构及其主要功能。完成了转向架的主要零部件的三维实体模型及虚拟装配，掌握三维实体仿真设计在铁路机车车辆产品的开发中的应用。 1、以SolidWorks为基础，建立转向架零件三维实体模型并进行虚拟装配。 2、运用有限元软件ANSYS WORKBENCH对车轮、车轴进行有限元分析，依据JIS-E-4501标准车轴静强度满足设计要求。根据UIC 510-5标准表明车轮静强度满足设计要求。 3、对一系弹簧悬挂装置的外簧进行静强度分析，结果表明其静强度满足设计要求。 关键词：转向架；CAD；静强度；有限元 ABSTRACT With the developme
